Introduction
The sprinklers sputtered, the pressure dropped, then silence. For any rural homeowner in midsummer, that’s more than an inconvenience—it’s brown patches on a once-green lawn, thirsty gardens, and frantic calls for help. A well system that can’t keep up with irrigation is either mis-sized, mis-installed, or simply built from cheaper components that never belonged in a well in the first place.
Meet the Saldivar family. Javier Saldivar (41), a forestry technician, and his spouse, Priya (39), a remote CPA, live on 3 acres outside Klamath Falls, Oregon with their kids—Rhea (10) and Mateo (7). Their 165-foot private well fed the home and four irrigation zones until a plastic-bodied 3/4 HP Red Lion submersible cracked under pressure cycling last July. With mounting repair bills and water restrictions looming, Javier needed a real solution. We sized them into a Myers Pumps Predator Plus submersible with a Pentek XE motor, 300 series stainless steel build, and staging matched to their TDH and sprinkler demand. Water came back strong, consistent, and affordable to run.
In this guide I’ll show you, step-by-step, how to plan and set up a Myers Pump for lawn sprinklers—precise GPM rating and pump curve sizing, stainless construction advantages, motor efficiency and wiring choices, controls that stabilize irrigation pressure, best-practice installation components, irrigation integration essentials, long-term protection and maintenance, troubleshooting, and how PSAM ships what you need fast.

Let’s get your irrigation back to lush and leak-free.
#1. Sizing the System for Sprinklers and Home Water — Matching GPM, TDH, and Stages with Pump Curve Analysis
Oversizing wastes electricity; undersizing starves zones. Reliable sprinklers start with an honest calculation of sprinkler demand and TDH from your well to the yard, then aligning it with a pump curve for a submersible well pump that hits the mark without straining.
Here’s how I frame it in the field. Start by totaling your zone flow: count heads per zone, multiply by each head’s nozzle GPM, and add 10–15% for friction and seasonal tweaks. For most lawns, a 10–14 GPM target at 50–60 PSI is typical. Next, calculate TDH: static water level to ground elevation, plus friction loss in the 1-1/4" NPT drop pipe, lateral runs, filters, and valves, plus your desired pressure at the sprinkler. That number drives the staging and horsepower—often 1 HP for medium wells and 1.5 HP for deeper or high-pressure turf nozzles.
For the Saldivars, four zones averaged 3.2–3.8 GPM each with rotors needing 55 PSI at the farthest head. Their static level sits at 95 ft in a 165 ft well. Factoring elevation, friction, and desired pressure, I sized them into a Myers Predator Plus Series 1 HP, multi-stage build that delivers 12 GPM at 58 PSI right on the curve—steady, quiet, and efficient.
Sprinkler Demand and Pressure Targets
- Identify design pressure at the head (rotors often 50–55 PSI; sprays 30–40 PSI). Multiply nozzle GPM by head count per zone; use the highest-flow zone as the system target. Add 10–15% overhead for filters, tees, backflow, and seasonal growth of the system.
A properly set target pressure means even coverage and green corners—no dry crescents or misting waste.
Total Dynamic Head (TDH) and Friction Reality Check
- TDH = static lift + elevation + pressure conversion (PSI x 2.31) + friction. Use conservative friction factors: older poly lines, elbows, and aged valves add resistance. Pipe size matters; upsizing laterals trims friction and stabilizes pressure at distant heads.
Get TDH wrong, and your pump works too hard. Get it right, and it coasts in its efficiency sweet spot.
Aligning with the Myers Pump Curve
- Match your TDH and required GPM to the pump curve for the selected HP and stage count. Keep operation near BEP for 80%+ hydraulic efficiency and longest service life. Validate that the shut-off head exceeds your well’s maximum lift and system losses.
Rick’s recommendation: size the pump to the highest-demand zone, then throttle lesser zones with zone valves and pressure regulation. Your lawn doesn’t need a fire hydrant; it needs consistent, design-matched water.
Key takeaway: Sizing to the curve is non-negotiable. Do it once, do it right, and your Myers system will reward you for years.
#2. Stainless Durability Where It Counts — 300 Series Stainless Steel, Engineered Impellers, and Threaded Assembly
Lawn irrigation punishes materials: mineral-rich water, daily cycling, grit. A 300 series stainless steel pump shell, discharge bowl, shaft, and suction screen resist corrosion and pitting for the long haul. Add Teflon-impregnated staging and self-lubricating impellers, and you’ve got a pump built to shrug off abrasives that chew up lesser brands.
In practical terms, stainless protects critical tolerances. Corrosion blooms or scaling inside cast components degrade efficiency, warp impeller channels, and shorten bearing life. Myers’ stainless internals and self-lubricating engineered composite impellers keep clearances tight and flow smooth. When you’re watering a lawn at dinner time and running a dishwasher, tight tolerances equal steady pressure and fewer nuisance callbacks.
The Saldivars fought sand fines every August. Their prior thermoplastic housing scarred, then cracked at the volute from pressure cycling. With a stainless Predator Plus and proper filtration, the family’s sprinklers now blanket evenly—no sudden dips, no angry zones starving the far heads.
Why Stainless Steel Wins on Wells and Irrigation
- Stainless resists acidic pH and high-iron conditions common in many private wells. Structural strength handles pressure fluctuations from zone changes and start/stop cycles. Cleanability matters: stainless responds to acid clean-outs if iron fouling ever appears.
Real durability is invisible when it’s working—no leaks, no flex, no creep.
Teflon-Impregnated Staging Built for Abrasion
- Self-lubrication reduces wear on bearings and wear rings when fines sneak past your intake screen. Stable performance curve over time; less edge rounding on impellers means consistent pressure. Lower friction equals lower amperage draw for a given flow—savings you’ll see on the meter.
Grit happens. Build for it, or budget for replacement.
Threaded Assembly = Field Serviceable
- Myers’ threaded assembly allows stage replacement and repair without junking a whole pump. Contractors save time; homeowners save money on the life-cycle of the system. If a seal or wear ring needs attention, you’re back online fast—no weeks-long downtime.
Pro tip: Pair stainless durability with a proper intake screen and a spin-down filter upstream of irrigation valves. That’s how you keep a great pump great.
Key takeaway: Stainless and self-lubricating staging are the quiet heroes behind long service life—exactly what an irrigation system needs.
Detailed Comparison: Myers vs Goulds and Red Lion in Irrigation Duty
From a materials standpoint, Myers Pumps leverage 300 series stainless steel from shell to suction screen, while many Goulds Pumps residential models retain cast components that can pit in acidic or iron-laden water. On the abrasion front, Myers’ Teflon-impregnated staging and self-lubricating impellers minimize wear from grit and fines. Thermoplastic-heavy Red Lion models simply don’t have the structural stiffness to hold tolerances under pressure cycling; micro-cracks propagate until a mid-season failure stops the show.
Applied in the yard, this plays out as real coverage. A stainless, multi-stage Myers holds pressure steadier when zones switch, keeping rotors from drooping. Cast or thermoplastic housings flex more under rapid changes, so pressure hunts; head-to-head spacing goes off, and the lawn shows it in dry streaks. Service life follows: we see 8–15 years from Myers irrigation duty when sized right and filtered. Goulds can do decent years in “clean” water, but corrosion hotspots shorten the curve. Red Lion thermoplastic units often present cracks or seal issues by year 3–5 in real irrigation use.
Value over time? A single Myers install with PSAM support beats two or three budget replacements, slashes emergency calls, and anchors consistent turf health. If you want coverage that doesn’t quit, the Predator Plus is worth every single penny.
#3. Motor and Efficiency That Pay Back — Pentek XE High-Thrust, BEP Operation, and Energy Savings
When irrigation runs 4–6 evenings a week, motor quality shows up on your electric bill. The Pentek XE motor on Myers Predator Plus delivers efficient torque across the stages, protected by thermal overload protection and hardening against surges with integrated lightning protection. Keep the duty cycle in the BEP neighborhood, and you’ll see 80%+ hydraulic efficiency in real-world flow.
In practice, that’s fewer amps for the same water—and cooler windings. High-thrust motor design resists axial loading from multi-stage impellers when you’re pushing 50–60 PSI for rotor heads. Everything stays straighter, cooler, and quieter. Pair it with balanced staging, and you’re not fighting vibration or thrust bearing fatigue.
At the Saldivars’, a 1 HP Predator Plus running ~12 GPM at 58 PSI averaged 7.4–7.9 amps at 230V. The old pump pulled similarly on paper, but its friction and slippage drove higher currents under load. Their summer bill dropped by roughly 12% compared to the previous two years—same watering schedule, more even coverage.
Why High-Thrust Matters for Sprinklers
- Rotor zones impose continuous pressure; axial loads stack on bearings over hours. High-thrust motors keep shaft deflection in check; less wobble means less wear. Smooth startup torque reduces water hammer risk in marginal systems.
It’s not just about starting—staying strong for two hours straight is the real https://www.plumbingsupplyandmore.com/convertible-shallow-well-jet-pumps-1-2-hp.html test.
Operating Near BEP = Measurable Savings
- Align flow and TDH so the pump works where the curve is fat and efficient. Expect up to 20% annual operating cost reduction vs off-BEP or bargain builds. Cooler operation extends insulation life and bearing service intervals.
Electricity prices won’t trend down. Efficiency is the hedge.
Protection Built In
- Thermal overload protection stops spiral-of-death heat events in low-flow or dry conditions. Lightning protection helps preserve windings during distant strikes and spikes. Thoughtful winding design and coatings help survival through adverse events.
Rick’s recommendation: Pull a fresh amp reading at each zone once a season. If amps are climbing with no change in flow, you’ve got friction or fouling to tackle early.
Key takeaway: Better motors do more than “run.” They run cooler, straighter, and cheaper—season after season.
Detailed Comparison: Myers vs Franklin Electric in Controls and Maintenance
Motor tech is only part of the equation. On the control side, Franklin Electric submersibles commonly integrate with proprietary control boxes and, in many markets, specialized dealer networks for troubleshooting. Myers Predator Plus Series, by contrast, offers field-serviceable threaded assemblies and flexible 2-wire or 3-wire options that any qualified contractor can maintain. Efficiency-wise, Myers harnesses Pentek XE high-thrust motors designed to hold 80%+ hydraulic efficiency near BEP, while many standard-motor setups lose efficiency under high-pressure irrigation duty.
In application, that means less downtime. With Myers, we can open, service, and reassemble without replacing the entire stack; installers in rural regions appreciate parts availability through PSAM rather than waiting on a dealer gatekeeper. From zone pressure checks to torque arrestor adjustments, the Myers platform respects the contractor’s time and the homeowner’s wallet. Lifespan comparisons favor Myers when cycle counts rise due to irrigation schedules—self-lubricating staging and practical serviceability keep the system in spec.
Over years, the cost curve is clear. Avoiding dealer-only constraints, reducing part-swaps, and running cooler with efficient staging equals fewer service calls and smaller energy bills. For independent installers and rural homeowners alike, Myers’ openness and reliability are worth every single penny.
#4. Controls that Make Sprinklers Happy — 2-Wire vs 3-Wire, Pressure Switch, and Tank Strategy
Watering systems hate pressure swings. Zoned irrigation amplifies short cycling if your controls aren’t set up right. Myers supports both 2-wire configuration (capacitor internal to motor) and 3-wire configuration (external control box), giving you options to fit budget and service preferences. Add a properly sized pressure tank and a tuned pressure switch, and you’ll keep runtime long and starts minimal—good for turf and motors alike.
For 10–14 GPM sprinkler zones, a classic 40/60 switch can work well if the tank is larger (think 60–86 gallons total volume), or you can use a 50/70 for taller rotors. The more drawdown the tank provides, the fewer starts per hour, which protects bearings and windings. If you want even tighter pressure regulation, a constant-pressure valve controlled system can hold a set PSI and limit cycling, but it requires correct bypass and thermal considerations.
Javier and Priya opted for a 2-wire Predator Plus to simplify wiring—no external box to mount or troubleshoot—and a 62-gallon tank with a 50/70 switch. The result? Smooth transitions between zones, minimal pump starts, and rotors that throw a consistent radius across the property.
2-Wire vs 3-Wire in the Real World
- 2-wire: Fewer components, easier DIY-friendly swap, lower upfront cost. 3-wire: External box offers service flexibility and start component access. With Myers, both are supported, giving you a choice without locking into proprietary gear.
Installation should match your comfort level and service plan.
Pressure Tanks and Switches for Irrigation
- Larger pressure tank volume reduces starts; aim for <10 starts/hour during irrigation. Set <strong> pressure switch ranges to the nozzle’s ideal pressure plus upstream losses. Keep pre-charge 2 PSI below cut-in; verify annually.
A calm, long-running system keeps turf green and motors cool.
Optional Constant Pressure Strategy
- A properly sized control valve can hold set PSI for rotors; great for even throw. Ensure bypass and minimum flow to keep the pump cooled and within curve limits. Anti-cycling controls prevent bang-bang starts on small zones.
Rick’s recommendation: For most residential lawns, a right-sized tank and dialed 50/70 switch on a Myers 2-wire is the sweet spot of performance and cost.
Key takeaway: Control the starts and you control the costs. Myers gives you wiring flexibility and pressure stability to run irrigation right.
#5. Installation That Lasts — Pitless Adapter, Check Valve, Drop Pipe, and Proper Wiring
Permanent reliability is built during install day. Use a pitless adapter to get below frost, add a spring-loaded check valve above the pump if not integrated, choose the correct drop pipe size, and run proper gauge wire. It’s the quiet workmanship that keeps you out of trouble five summers from now.
Most Predator Plus submersibles include an internal check valve; I like a second external check 10–20 feet above the pump in deep sets to prevent backspin on service. Use 1-1/4" drop pipe for 10–14 GPM irrigation demand to keep velocity and friction losses in check. Install a torque arrestor, cable guards, and an abrasion-resistant wire splice kit with heat-shrink butt splices. Seal the well with a corrosion-resistant well cap and document set depth for future maintenance.
On the Saldivar job, we set the Myers at 140 ft with 1-1/4" SDR drop, torque arrestor, and a brass pitless. The previous pump had no torque control and undersized poly, which added friction and shortened throw on their far rotors. After the upgrade, zone three finally reached the back fenceline.
Drop Pipe, Velocity, and Friction
- Keep pipe velocity ≤ 5 ft/s to limit friction and water hammer. Size laterals to reduce head loss; upsizing a single run can stabilize an entire zone. Minimize elbows and tees near the tank tee to smooth flow.
Small changes upstream pay big dividends at the nozzle.
Electrical Done Right
- Follow 230V single-phase specs and match amperage draw to the panel rating. Protect splices with dual-wall adhesive heat shrink; moisture is the silent enemy. Grounding and surge protection matter—especially in lightning-prone regions.
Electric reliability is irrigation reliability.
Hardware That Prevents Callbacks
- Pitless adapter keeps connections accessible and frost-proof. Secondary check valve placement prevents spin-back and start-up stress. Torque arrestor and cable guards protect against start torque chafe.
Key takeaway: Use the right hardware, installed cleanly, and you’ll stop 90% of common failures before they start.
#6. Marrying Pump and Irrigation — Filtration, Backflow, Pressure Regulation, and Zone Design
A stellar pump still needs a cooperative irrigation system. Start with sediment protection, a quality backflow preventer, and zone-by-zone regulation that matches nozzle specs. The result is even distribution, efficient watering windows, and a lawn that plays nice with your well’s recovery rate.
Install a spin-down or disc filter upstream of the irrigation manifold to catch fines before valves and rotors. Add a tested backflow preventer per local code to protect your potable lines. For rotors, regulate zones to 50–60 PSI; for sprays, drop to 30–40 PSI to avoid misting. Group heads by sun/shade and slope, and size laterals so the farthest head still sees design pressure.
The Saldivars reworked two zones with pressure-regulated heads and a master valve. Suddenly, the “mysterious” dry strip disappeared—pressure stabilized, nozzle precipitation rates matched, and runtime dropped by 12 minutes per zone.
Filtration and Water Quality
- A 100–200 mesh filter protects valves and rotors; clean it monthly during peak season. High iron? Consider periodic acid clean-outs or an iron filter upstream of irrigation. In sandy aquifers, filtration is non-negotiable to protect impellers and bearings.
Filter the cheap stuff to protect the expensive stuff.
Backflow and Code Compliance
- Use the correct backflow device (PVB, DCVA, RPZ) per code and hazard level. Test annually if required by your jurisdiction. Proper installation orientation and height prevent nuisance leaks and failures.
Water safety pairs with lawn success—never compromise here.
Pressure Regulation and Zone Balance
- Regulated bodies or zone PRVs hold each set of heads at design PSI. Balance precipitation rates; match heads/nozzles within a zone. Fine-tune runtime after observing coverage; small tweaks prevent overwatered patches.
Key takeaway: Great irrigation components make a great pump look even better. Build the manifold like you build the well—thoughtfully.
#7. Longevity Plan — Warranty, Protection Devices, and Seasonal Maintenance
Longevity isn’t luck. Myers’ industry-leading 3-year warranty anchors a quality platform, but protecting it with surge suppression, correct tank sizing, and routine checks is how you reach the 8–15 year service window—and beyond with good care.
At the panel, add a whole-house surge protector; out at the pump, the Pentek XE motor includes thermal overload protection and lightning protection advantages that help it ride out spikes and marginal flow conditions. Size the pressure tank to keep starts down, keep pre-charge set correctly, replace worn pressure switches, and flush filters routinely. Each item adds a little life; together, they add years.
Javier logs monthly checks: filter flush, zone pressure spot checks, and listening for chatter at start-up. Two minutes with a notepad, and his Myers runs quiet, cool, and predictable.
Warranty and Certifications
- Myers’ 3-year warranty outpaces the typical 12–18 months in the market. UL listed, often NSF and CSA certified builds verify safety and performance. PSAM stands behind the sale with accessible support and documentation.
Coverage is great; fewer claims are better. Build to avoid the claim.
Electrical and Hydraulic Protections
- Surge protection and clean grounding save motors from invisible abuse. Anti-cycling via proper tank sizing reduces bearing and contactor wear. Periodic amp-draw testing catches friction issues early.
Measure before it turns into a repair.
Seasonal Checklist
- Spring: Test backflow, flush filters, verify zone pressures. Mid-summer: Amp check under peak watering, inspect wire splices at the well cap. Fall: Drain or insulate exposed manifolds, verify well cap security.
Key takeaway: Thoughtful protections turn a good pump into a decades-long asset.
Detailed Comparison: Myers vs Red Lion for Real-World Irrigation Cycles
Irrigation is relentless on housings and seals. Under repeated start/stop cycles and pressure shifts between zones, thermoplastic pump bodies like many from Red Lion develop stress concentrations; micro-cracks at bosses and volutes become leaks or catastrophic failures. Myers Predator Plus, built with 300 series stainless steel casings and engineered composite stages, resists creep and holds alignment so impeller-to-diffuser clearances don’t wander. Pair that with a Pentek XE motor’s cooler operation at BEP, and Myers’ overall system stress is simply lower.
On a residential yard with four to six evening cycles a week, we see a spread in service life: Myers commonly delivers 8–15 years in irrigation duty with basic filtration and correct sizing. Red Lion thermoplastic units? Many are limping by year three to five once pressure cycling takes its toll. Energy use trends the same direction—degrading tolerances raise amperage draw. Add in the Myers 3-year warranty (vs. Common 12-month coverage on budget lines), and downtime risk is unmatched.
Homeowners watering from private wells need predictability. Stainless construction, self-lubricating staging, and efficient motors that thrive at irrigation pressures translate to healthier lawns and fewer midnight runs to the breaker. For a yard that stays green and a bill that stays calm, Myers is worth every single penny.
#8. Troubleshooting Like a Pro — Pressure Loss, Cycling, and Flow Imbalances
Even great systems need smart eyes when something changes. A lawn that suddenly shows dry arcs or a pump that short-cycles is sending a message. Work through a simple diagnostic tree and most irrigation hiccups are solved without a pull.
Start with pressure at the tank tee: if the gauge hunts rapidly, suspect a failing check valve or air charge in the pressure tank. If pressure holds steady at the tee but the far heads droop, check zone regulators, clogged filters, or lateral leaks. Rising amperage at the same flow hints at fouling or stage wear; stable amperage with falling flow hints at a suction restriction or partially closed valve.
When the Saldivars noticed zone two falling off, a quick filter inspection found silt from recent well work. A 5-minute flush restored design pressure. No pump pulls, no drama.
Short-Cycling and Control Fixes
- Verify tank pre-charge (2 PSI below cut-in). Low air means tiny drawdown and rapid cycling. Look for leaking zone valves or faucets after-hours. A failed or sticky pressure switch can chatter; replace if pitted.
Cycling kills motors. Fix controls first.
Flow Loss and Coverage Issues
- Clean or replace the filter; check for debris at nozzle screens. Confirm PRV or regulated heads are set correctly. Listen for hissing at manifolds—buried leaks betray themselves.
Coverage returns when flow and pressure are back in harmony.
Electrical Clues
- Pull live amp-draw at irrigation zone flow; record baseline each season. A jump in amps at same flow = more friction in the pump; schedule maintenance. A drop in amps with weak flow = suction or line restriction.
Key takeaway: A gauge, an amp clamp, and 10 quiet minutes will solve most mysteries.

Frequently Asked Questions
1) How do I determine the correct horsepower for my well depth and household water demand?
Start with your sprinkler zone requiring the most water. Add up nozzle flows to get a GPM rating—often 10–14 GPM for typical lawns—and set a target pressure (50–60 PSI for rotors, 30–40 PSI for sprays). Next, calculate TDH: static lift plus elevation, friction losses, and pressure converted to feet (PSI x 2.31). Match that GPM/TDH point to a pump curve for the Myers Predator Plus Series. In many 120–200 ft wells, 1 HP handles 10–12 GPM at irrigation pressure; 1.5 HP fits deeper or higher-pressure needs. For example, a 12 GPM zone at 58 PSI with 100 ft static lift typically lands on a 1 HP multi-stage Myers. Rick’s recommendation: size to run near BEP for 80%+ hydraulic efficiency. If in doubt between sizes, pick the model that puts your duty point closer to BEP—not simply “more horsepower.” PSAM provides curves and quick calcs to nail it the first time.
2) What GPM flow does a household need and how do multi-stage impellers affect pressure?
Most homes function well at 6–8 GPM; add irrigation and your peak demand jumps to 10–14 GPM per active zone. A multi-stage pump stacks pressure by adding impellers in series; each stage contributes head (pressure), so more stages equal higher pressure at a given GPM. The Myers design uses engineered composite impellers with tight tolerances, so you maintain pressure even as small abrasives pass through. With rotors, aim for 50–60 PSI at the head; with sprays, 30–40 PSI to avoid misting. The pump’s curve will show how many stages hit your target. In practice, a 1 HP Predator Plus might be 10–13 stages depending on the head needed. Rick’s tip: never spec pressure for the near head—always for the farthest head on the highest zone demand.
3) How does the Myers Predator Plus achieve 80% hydraulic efficiency compared to competitors?
Efficiency hinges on matching your duty point to the pump’s BEP and using low-loss materials and geometries. Myers Predator Plus employs Teflon-impregnated staging, slick self-lubricating impellers, and 300 series stainless steel flow paths that maintain smooth surfaces over time. Pair that with a Pentek XE motor that holds thrust alignment and resists heat rise under irrigation duty, and you convert more watts into water. Many competitors lose efficiency as components pit or as impeller edges wear from grit. At PSAM, we size your GPM and TDH to land near BEP on the curve; that’s where Myers hits 80%+ hydraulic efficiency in real lawns. The result is measurable: lower amperage draw at the same zone flow, cooler windings, and less money to paint your turf green.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps?
Submersible pumps live in a bath of minerals, gases, and shifting pH. 300 series stainless steel resists corrosion and pitting in environments where cast iron can suffer surface breakdown. Once cast surfaces pit, internal losses grow, impellers see higher friction, and efficiency falls. Stainless holds shape under cycling pressure loads common in irrigation—zone changes won’t flex it. On service day, stainless tolerates acid clean-outs for iron fouling far better than cast. Myers’ stainless shell, discharge bowl, shaft, and suction screen protect internal clearances that keep your pressure stable. In my field notes, stainless builds routinely survive 8–15 years; cast-heavy units in aggressive water often stumble earlier. For lawns relying on daily irrigation schedules, stainless is cheap insurance.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
Abrasion is the quiet thief of pump life. Teflon-impregnated staging provides a self-lubricating interface that reduces friction when fines slip past the intake screen. The engineered composite impellers in the Myers Predator Plus are formulated to resist edge rounding and maintain vane geometry, so the pump curve stays stable longer. Sand rounding an impeller translates into lower head and falling PSI at your rotors. With Myers, even when fines make an appearance, staging fights back, preserving both pressure and efficiency. Add a spin-down or disc filter upstream of your irrigation manifold, and you intercept the worst offenders before they reach valves and heads. I’ve seen gritty Great Basin wells keep a Myers humming a decade with this approach.
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
Two advantages: thrust handling and heat control. The Pentek XE motor resists axial loads from multi-stage impellers better than generic builds, keeping the shaft straight and bearing loads predictable. That alignment reduces internal friction, translating to lower amperage draw at the same flow. Second, superior thermal design—combined with thermal overload protection and surge hardening—keeps windings cooler. Cooler windings mean longer insulation life and fewer nuisance trips. In irrigation duty, where pumps run 60–120 minutes per zone set, that thermal advantage pays off immediately. Sizing your Myers to run near BEP compounds the benefit: you get both hydraulic and electrical efficiency in the same window.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor?
If you’re mechanically savvy and comfortable with electrical work, you can DIY a Myers submersible following code and safety practices. Use a pitless adapter, correct drop pipe sizing (often 1-1/4"), torque arrestor, cable guards, and a heat-shrink wire splice kit. Verify 230V wiring, grounding, and pressure switch settings; pressure tank pre-charge should be 2 PSI below cut-in. That said, pulling a pump is heavy, awkward work—many homeowners wisely hire a pro for set and seal, then handle manifold and irrigation tweaks themselves. PSAM ships the hardware and provides diagrams and curves. Rick’s recommendation: if your well is deeper than 150 ft or your wiring/panel is marginal, bring in a licensed contractor to ensure safe, code-compliant power and a leak-free pitless connection.
8) What’s the difference between 2-wire and 3-wire well pump configurations?
In a 2-wire configuration, the start components (like the capacitor) are integral to the motor. Wiring is simpler—fewer external parts, faster install, and lower upfront cost. In a 3-wire configuration, start components live in an external control box, allowing easier replacement of capacitors and relays without pulling the pump. Performance can be similar when sized to the curve; the choice often comes down to service philosophy and installer preference. For irrigation-heavy duty, many homeowners appreciate the simplicity of 2-wire Myers units; contractors sometimes choose 3-wire for serviceability. Either way, the Predator Plus line supports both, avoiding proprietary control requirements. Rick’s rule: pick the path that keeps your system maintainable with local parts and your comfort level.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance?
In typical residential irrigation and domestic service, expect 8–15 years from a Myers Predator Plus—and I’ve seen 20+ with meticulous filtration and proper sizing. Keys to longevity: operate near BEP, control cycling through a right-sized pressure tank, maintain clean filters, and keep an eye on amp draw once each season. Address grit with a spin-down filter and consider an iron filter if staining appears. Electrical protection (surge suppression and grounding) further lengthens life. Compare that to many budget pumps failing in 3–5 years under irrigation cycling; stainless materials, self-lubricating staging, and Pentek XE motors make the difference.
10) What maintenance tasks extend well pump lifespan and how often should they be performed?
Seasonally, flush your irrigation filter and check zone pressures; clean nozzle screens if coverage dips. Semi-annually, confirm tank pre-charge (2 PSI below cut-in), inspect the pressure switch contacts, and listen for chatter. Annually, pull an amperage draw reading at irrigation flow and compare to your baseline; rising amps can mean fouling or stage wear. Every few years, test backflow devices and verify electrical connections in the control area are clean and tight. In abrasive wells, service or upgrade filtration; in iron-prone wells, plan periodic clean-outs. These light-touch steps keep a Myers running at curve and stave off the early failures that plague under-maintained systems.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers delivers a market-leading 3-year warranty, outpacing the 12–18 month standard from many brands. Coverage addresses manufacturing defects and performance issues on the pump assembly and motor when installed per instructions. Combine that with UL listed safety and Made in USA quality control, and you’ve got both strong paper coverage and lower claim likelihood. Contrast this with budget pumps and short warranties that put the risk back on you during the exact years when cycling wear shows up. PSAM assists with documentation, troubleshooting, and, when warranted, the claim process. Rick’s take: strong warranty plus fewer claims is the real win—Myers checks both boxes.
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Let’s run it straight. A properly sized Myers Predator Plus costs more on day one but commonly runs 8–15 years. Over 10 years, you’re typically at one install, low maintenance, and lower electricity thanks to 80%+ efficiency near BEP. Budget pumps often see a mid-life failure at year 3–5—sometimes two replacements in a decade—plus higher energy from degraded internals. Add service calls, emergency shipping, lawn recovery costs from watering gaps, and the math tilts further. In our tracking, homeowners save 15–30% in total ownership costs with Myers vs. Repeat buys of budget models. If turf health and schedule reliability matter, paying for stainless construction and a Pentek XE motor is simply smarter.
Conclusion
A lawn irrigation system is honest with you. If the pump is undersized, materials are flimsy, or controls are sloppy, coverage falters and bills climb. A Myers Pumps Predator Plus submersible, sized to your GPM rating and TDH, built from 300 series stainless steel with Teflon-impregnated staging, and driven by a Pentek XE motor, gives you quiet, durable pressure season after season. Set it up with proper 2-wire or 3-wire controls, a right-sized pressure tank, and clean filtration, and you’ll land right on the curve with 80%+ efficiency and the industry’s strongest 3-year warranty behind you.
