A cold shower that turns into a trickle—then nothing—has a way of rearranging your plans. When your well pump dies, every faucet, toilet, and appliance in the house goes quiet. I’ve taken those Saturday morning calls for decades. In most cases, the root cause wasn’t the water; it was incorrect pump sizing. Undersized pumps short-cycle and burn up motors. Oversized pumps waste power, hammer plumbing, and pull wells down faster than they can recover.
Meet the Delgados—Ariana (36), a K-8 teacher, and Marco (38), an electrician—who live on 6 acres outside Las Vegas, New Mexico with their kids, Emiliano (8) and Sofia (5). Their 240-foot private well feeds a 2-bath home, a small garden with drip irrigation, and a barn with two frost-free hydrants. Their 3/4 HP Hallmark Industries submersible lasted just 3 years. First came gritty water, then the dreaded on-off cycling, and finally a seized motor. The installer had sized off a guess, not a pump curve. After two days hauling water, Ariana called PSAM and asked for a system that wouldn’t strand their family again.
In this guide, I’ll show you how I sized the right Myers pump for the Delgados—and how you can do the same. We’ll cover: estimating flow demand, calculating total dynamic head (TDH), matching horsepower to pump curves, choosing between 2-wire and 3-wire configurations, the benefits of 300 series stainless steel, why Pentek XE motors matter, staging for pressure performance, installation best practices, warranty and serviceability advantages, and real-world comparisons versus other brands. If you rely on a private well, these 10 steps will keep your taps running, your energy bills sensible, and your pump out of the truck for at least a decade.
Before we dive in, a few reasons I spec Myers Pumps through PSAM for critical water systems: an industry-leading 3-year warranty, 80%+ hydraulic efficiency near BEP, Made in USA construction, NSF/UL/CSA listings, and the Predator Plus Series’ 300 series stainless steel build that simply shrugs off corrosive water. Add the Pentek XE motor with thermal and lightning protection, and you’ve got durability with brains. That’s my kind of well partner.
Now, let’s size your pump like a pro.
#1. Start with Real Water Demand — GPM and Fixture Count Using Pump Curve Reality, Not Guesswork
Your pump must meet peak household demand without short cycling. Size GPM first, then match TDH and horsepower to a pump curve; anything else is gambling with your water.
Why it matters: Peak demand is when your pump works hardest—washer fills, someone showers, a hydrant runs. If your pump can’t meet that moment at the required pressure, pressure drops and cycling ramps up. I target 6–10 GPM for most homes, 12–20 GPM when irrigation or livestock are part of the equation.
Technically: Count fixtures and expected concurrent use. A 2–3 bath home with laundry and kitchen typically requires 7–10 GPM. Add drip irrigation at 2–4 GPM and a hydrant at 5 GPM, and you’ll want a 10–12 GPM rating. For the Delgados, we set 10 GPM peak based on two simultaneous showers (2.5 GPM each), a washer fill (2 GPM), and a drip zone (3 GPM). With a pressure switch at 40/60 PSI, the system needs to deliver that flow at roughly 60 PSI at the tank tee.
Ariana’s old pump was rated 7 GPM at 100 feet. At 240 feet plus friction and pressure, it never had a chance.
Fixture Audit and Demand Profile
List fixtures and typical overlaps. Dishwashers and front-load washers draw less, but showers and hose bibs drive peaks. Add a small buffer (1–2 GPM) for reality. Keep it pragmatic.
Use Conservative Irrigation Estimates
Sprinklers can be piggish. Drip is predictable. If you blend the two, size for the heaviest zone plus household baseline. Don’t promise the moon; just keep the showers steady.
Rick’s Recommendation
For most rural homes: start at 10 GPM and adjust up/down based on irrigation and hydrants. Then match to the right Myers Predator Plus curve. Meeting demand beats chasing pressure problems later.
Key takeaway: Define GPM before horsepower. Pumps don’t care about square footage; they care about flow and pressure.
#2. Calculate Total Dynamic Head (TDH) — Depth, Pressure, and Friction in One Clean Number
A pump doesn’t lift just water—it fights gravity, friction, and pressure. Get TDH right, and you’ll pick the right Myers submersible well pump every time.
Technically: TDH = vertical lift (pumping level to pressure tank) + pressure requirement (convert PSI to feet: PSI × 2.31) + friction loss in pipe and fittings. For the Delgados: pumping level at 180 ft (their static is 140 ft and tested drawdown puts pumping level at ~180 ft), plus 20 ft elevation to the tank, equals 200 ft of lift. Pressure at 60 PSI adds 138 ft (60 × 2.31). Friction at 10 GPM through 1" poly over 250 ft adds ~15–25 ft depending on fittings. TDH ≈ 200 + 138 + 20 = 358 ft (including friction). Round to 370 ft for safety.
Now you know the real number that matters on the pump curve.
Measure, Don’t Guess, Pumping Level
Static water isn’t pumping water. If you’ve got drawdown data, use it. If not, assume 30–60 ft more than static in deeper wells. Field-testing during a pump pull is even better.
PSI-to-Feet Conversion
Want 60 PSI at the tank? That’s ~138 ft of head. For 50 PSI, use 115 ft. Your pressure switch setting dictates this number.
Friction: Pipe Size Is Your Friend
Upsizing drop pipe to 1-1/4" can shave head and improve efficiency. I calculate friction using manufacturer charts and add a buffer for elbows, tees, and the pitless adapter.
Key takeaway: TDH is non-negotiable. With TDH locked in, you can select the right stages, horsepower, and flow.
#3. Match TDH to the Right Myers Predator Plus Curve — Choose Horsepower and Stages for Best Efficiency Point (BEP)
A pump chosen at the Best Efficiency Point (BEP) runs cooler, lasts longer, and saves energy. This is where Myers Predator Plus shines.
Technically: On the curve chart, find your TDH on the Y-axis (feet) and your GPM on the X-axis. Where they cross—choose the model that hits that point near the middle of the efficiency island. For the Delgados at 10 GPM and ~370 ft TDH, a Myers 1 HP Predator Plus, multi-stage, 230V, with a shut-off head near 430–450 ft fits perfectly. It provides margin without oversizing. A 3/4 HP would ride the right edge of the curve (hotter motor, shorter life). A 1.5 HP would push too much flow and cost more to run.
For most 150–280 ft wells at 7–12 GPM, start your evaluation at 3/4 HP to 1 HP. Deeper than 300 ft, 1–1.5 HP often wins on curve placement.
Staging and Shut-Off Head
More stages = more head at a given flow. Select staging that gives at least 10–15% headroom above your TDH. That keeps pressure steady during minor drawdown increases.
Amperage Draw and Voltage
At 230V, the Pentek XE motor runs cooler with lower amperage than 115V equivalents in higher HP. Cooler motors live longer. It’s that simple.
Check the Curve for 40/60 Performance
Make sure the curve shows 10 GPM at 60 PSI (≈138 ft) plus your lift and friction. Don’t size off 30/50 if you’re running 40/60.
Key takeaway: Curve-first sizing is how you earn 8–15 year pump life, not 3–5 years.
#4. Choose 2-Wire or 3-Wire Configuration — Simplicity vs. Serviceability in Real-World Wells
Configuration affects installation, troubleshooting, and cost. 2-wire pumps simplify installation. 3-wire pumps put capacitors and relays in a control box above ground.
Technically: A 2-wire well pump (actually two power leads plus ground) contains start components in the motor, reducing external parts and wiring. Faster to install, fewer points of failure topside. A 3-wire well pump uses an external control box—handy for diagnostics and replacement of start gear without pulling the pump. Both options exist across Myers Predator Plus models, and both are reliable.
For homeowners with straightforward wells and clean power, I often recommend 2-wire for simplicity. For contractors or wells with known cycling issues or marginal power, 3-wire can make service faster.
The Delgados chose a 2-wire configuration at 230V with a quality surge suppressor—clean install and fewer components to mount at the tank tee.
Control Box Considerations
A control box adds cost and a part to mount, but it can save a pull if start components fail. For https://www.plumbingsupplyandmore.com/1-2-hp-submersible-well-pump-9-stages-for-deep-wells.html rentals or critical uptime, 3-wire has merit.
Voltage and Breaker Sizing
Most 1 HP and above should run 230V. Confirm amperage draw against breaker and wire size—voltage drop kills pumps.
Pro Tip: Surge Protection
Lightning happens. The Pentek XE motor includes lightning protection, but a panel-mounted surge protector adds a cheap layer of insurance.
Key takeaway: Both configurations work. Pick based on serviceability preference and your electrical reality.
#5. Specify Materials that Survive Your Water — 300 Series Stainless, Self-Lubricating Impellers, and Corrosion Resistance
Wells don’t fail in a lab; they fail on bad water. Build matters. 300 series stainless steel and Teflon-impregnated staging keep pumps alive when grit and acidity try to chew them up.
Technically: The Myers Predator Plus uses 300 series stainless for shell, discharge bowl, shaft, coupling, wear ring, and suction screen—all lead-free and corrosion resistant. The impeller stages are an engineered composite with self-lubricating impellers designed to resist abrasion. Add an internal check valve and threaded assembly for field service. Compare that to cast iron components or thermoplastic housings—which I routinely see crack, pit, or swell under thermal and pressure cycling.
Ariana’s previous pump came out with worn vane edges, loaded with sand scoring. The Myers stages handle that far better, extending life while maintaining flow.
When Your Water is Hard or Acidic
Acidic pH attacks cast iron. Hard water leaves scale that drags on inefficient designs. Stainless and smooth composite staging reduce that drag.
Grit and Sand Tolerance
No pump loves sand, but Teflon-impregnated contact surfaces and engineered composite impellers don’t erode like cheap plastics.
Cable Guard and Intake Screen
Protect the motor leads and block debris early. I install cable guards at intervals and check the intake screen for damage during pulls.
Key takeaway: Material quality is not marketing fluff; it’s your pump’s life insurance.
#6. Pressure, Tanks, and Cycle Control — Protect Your Motor and Plumbing for the Long Haul
Pressure isn’t just a number; it sets the stage for cycling. Correct pressure tank sizing, pressure switch setting, and check valve placement keep your Pentek XE motor out of the danger zone.
Technically: Short cycling cooks motors and hammers plumbing. A properly sized tank provides at least one minute of run time at pump output. At 10 GPM, that’s a minimum of 10 gallons of drawdown. A 44-gallon tank offers about 12–14 gallons drawdown at 40/60 PSI—adequate for many homes. Add a cycle stop valve if pressure stability across variable demand is critical, but always verify the pump curve can handle the backpressure.
The Delgados upgraded to a 62-gallon steel tank for added buffer—longer cycles, cooler motor, quieter system.
Set 40/60 or 50/70 Intentionally
Higher cut-out means higher head. If you’re going 50/70 PSI, revisit your TDH and pump curve. Don’t steal your own capacity.
Check Valve Strategy
The internal check is standard. Add a line check at the tank tee only if the vertical column is long or the drop pipe is elastic. Too many checks invite water hammer.
Air Charge and Annual Checks
Tank air plumbingsupplyandmore.com precharge should be 2 PSI below the cut-in. Verify yearly. A waterlogged tank destroys pumps—fast.
Key takeaway: Pressure and cycling control cost less than a single motor replacement. Protect the investment.
#7. Installation Details that Decide Reliability — Drop Pipe, Pitless, Splices, and Safety Gear
A great pump can be undone by a bad install. Use quality drop pipe, seal the pitless adapter, make bulletproof wire splice kits, and secure a torque arrestor and safety rope. The details pay you back.
Technically: For 200–300 ft wells, 1-1/4" drop pipe (poly or SCH 80 PVC) minimizes friction and reduces head. Use stainless clamps—double them and oppose the screws. At the wellhead, a sealed well cap and carefully set pitless keep groundwater and pests out. All electrical splices should be heat-shrink, adhesive-lined, rated for submersible use. A torque arrestor prevents startup spin from chafing wire; I also secure the cable every 10–20 feet with stainless bands, plus a dedicated safety rope.
We redid the Delgados’ splices and switched to 1-1/4" poly. Friction dropped, and pressure stabilized at high flow.
Wire Gauge and Voltage Drop
Run wire sized to limit voltage drop to 3% or less. Undersized wire overheats motors and erodes torque.
Pitless Adapter Alignment
Crooked pitless = leaks and freeze risk. Set it square, grease the O-rings, and pull-test before backfilling.
Discharge Size and Tank Tee Layout
Use 1-1/4" NPT where possible to the tank tee. Tee, gauge, relief valve, drain, and switch should be accessible and leak-free.
Key takeaway: Don’t lose a premium Myers Pump to a $3 clamp or a cheap splice.
#8. Warranty, Serviceability, and Real ROI — Why Myers Predator Plus Pays You Back
When it comes to warranty and serviceability, Myers Predator Plus is engineered for ownership, not just the sale.
Technically: An industry-leading 3-year warranty beats the short coverage common in the market. The threaded assembly allows field service of stages and nitrile rubber bearings without replacing the entire unit. Add Pentek XE motor protection—thermal overload and built-in lightning protection—and you reduce nuisance failures. With field serviceable design, PSAM or your contractor can keep you running with a fraction of the cost of full replacement.
For Ariana and Marco, that warranty and the ability to repair on-site turned a “cross your fingers” purchase into a confident plan. That peace of mind matters when your home depends on a private well.
Made in USA, Certified, Factory Tested
With NSF, UL, and CSA listings and factory tested performance, you’re not guessing at quality. You’re ordering it.
Fast Shipping from PSAM
Emergency? PSAM can ship in-stock pumps same day. Panicked Pauls sleep better knowing water is hours—not days—away.
Documentation and Curves at Your Fingertips
Complete spec sheets, parts lists, and curves let you service smart. That’s how pros do it.
Key takeaway: A pump is a system decision. Myers builds it to be owned, maintained, and trusted for the long term.
#9. Honest Brand Comparison — Why Myers Predator Plus Outperforms Goulds and Red Lion in Real Wells
Comparison matters when your kitchen sink depends on it. Here’s the field reality I see on jobsites across the country.
Technical performance: Myers’ 300 series stainless steel shell and discharge components resist corrosion where Goulds Pumps often rely on cast iron elements that can pit in acidic or mineral-heavy water. The Teflon-impregnated staging and engineered composite impellers in the Predator Plus maintain efficiency in sandy wells better than many standard composites. Meanwhile, Red Lion units with thermoplastic housings can deform or crack under repeated pressure and thermal cycles—especially at higher shut-off heads in deep wells. The Pentek XE motor in Myers delivers high-thrust reliability with lower amperage draw, supporting 80%+ hydraulic efficiency near BEP.
Real-world differences: In the field, Myers units are easier to maintain thanks to threaded assembly and serviceable wear parts. I regularly observe 8–15 year service life on Predator Plus when sized correctly, compared to 3–5 years from economy thermoplastic submersibles I’ve pulled. With a true 3-year warranty, and fast parts availability through PSAM, downtime and ownership costs drop.
Value conclusion: For households living on private wells, resilience beats sticker price. Stainless construction, efficient motors, a real warranty, and field serviceability make Myers Predator Plus worth every single penny.
Use Case: The Delgados’ Corrosive Water
After a lab test showed slightly acidic water, stainless was non-negotiable. The Predator Plus’ materials eliminate the pitting we see on iron-heavy builds.
Irrigation + Household Balance
When sprinklers run, staged impellers maintain stable pressure lineside; flimsy thermoplastics can lose edge profile fast under grit.
PSAM Support
Need a control box or tank tee today? PSAM’s inventory keeps your project moving—no costly standby days.
Key takeaway: Materials and motors win over marketing. Myers delivers the goods you actually need.
#10. Put It All Together — A Step-by-Step Sizing Walkthrough Using PSAM Myers Pump Selection

Comparison Deep Dive: Myers vs. Franklin Electric and Grundfos — Installation, Efficiency, and Ownership
Technical analysis: Myers Predator Plus pairs 300 series stainless steel hydraulics with a Pentek XE high-thrust motor, achieving 80%+ efficiency when operated near BEP. In contrast, while Franklin Electric motors are respected, their submersible packages often depend on proprietary control boxes and dealer networks, which can complicate service. Grundfos offers premium performance but frequently leans into 3-wire or more complex control solutions that add upfront cost and require specific configuration knowledge. For homeowners and small contractors, Myers keeps horsepower, stages, and wiring simple without sacrificing performance.
Application differences: Myers’ field serviceable threaded build makes on-site repairs practical—replace stages, service nitrile rubber bearings, and get back online. Franklin’s ecosystem can tie you to dealer-only parts and procedures. Grundfos excels in specialized applications but introduces complexity that doesn’t always translate to value on a typical rural home. With Myers’ 3-year warranty, access to parts, and broad performance envelopes—from 7–8 GPM to 20+ GPM and 250–490 ft shut-off head—you cover most residential wells without hoop-jumping.
Value conclusion: For homeowners and contractors seeking reliable water without premium complexity, the Predator Plus equation—stainless hydraulics, efficient motor, simple service, and PSAM support—is worth every single penny.
FAQ: Expert Answers to Sizing and Ownership Questions
1) How do I determine the correct horsepower for my well depth and household water demand?
Start with your required flow, typically 7–12 GPM for a single-family home. Next, calculate TDH: add pumping level to the pressure tank (feet), convert your desired PSI to feet (PSI × 2.31), and include friction loss. Plot that GPM/TDH point on the Myers Predator Plus pump curve. Choose the model that places your point near the best efficiency point (BEP), typically mid-curve. As a rough guide: 60–150 ft wells often fit 1/2–3/4 HP, 150–280 ft wells align with 3/4–1 HP, and 280–400 ft can justify 1–1.5 HP depending on flow. Always verify against the actual curve. For example, at 10 GPM and 370 ft TDH, I’ll select a 1 HP, 230V Predator Plus with adequate stages for a shut-off near 430–450 ft. Overpowering wastes energy and can cause valve chatter; underpowering shortens motor life. When in doubt, call PSAM—send your well report and fixture list, and I’ll walk you through it.
2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
A typical 2–3 bath home runs well at 7–10 GPM. Add irrigation or livestock, and you may need 12–15 GPM during peak use. Flow must be delivered at your desired pressure—usually 40/60 PSI. Multi-stage impellers allow a submersible to build higher head at the same flow by stacking stages. Each stage contributes head; together they meet your TDH requirements. On a Myers submersible well pump, adding stages increases the attainable pressure without sacrificing GPM at a given horsepower—within limits set by the pump curve. This is why a properly staged deep well pump can supply steady 60 PSI at the tank while lifting from 200–300 ft down. For instance, a 10 GPM, 1 HP Predator Plus with the right stage count will hold 10 GPM at ~370 ft TDH, giving showers, washer, and a hydrant stable pressure simultaneously.
3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
Efficiency comes from hydraulic geometry, materials, and motor pairing. The Predator Plus uses engineered composite impellers and precise diffuser design, minimizing turbulence and internal losses. The Pentek XE motor adds high-thrust capability with optimized amperage draw, keeping the motor in its sweet spot when the pump operates near BEP. Combine that with reduced friction from Teflon-impregnated staging and smooth 300 series stainless steel components, and you’ll see 80%+ hydraulic efficiency where many competitors sit lower at equivalent operating points. Efficiency isn’t abstract—it lowers your kWh per gallon. On a 1 HP unit delivering 10 GPM, expect noticeable savings over less efficient builds, especially when the pump runs for longer irrigation cycles. Proper sizing to BEP seals the deal; a great pump sized poorly won’t deliver its efficiency promise.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps?
Below ground, water chemistry matters. 300 series stainless steel resists corrosion from dissolved minerals and acidic water that will pit and weaken cast iron over time. Stainless maintains dimensional stability, which preserves clearances in the pump stack—critical for maintaining GPM rating and head. It also handles thermal expansion and repeated pressure cycles without cracking—something I’ve seen on cast composites. In shallow to deep wells with iron, sulfur, or low pH, stainless drastically extends service life. The Myers Predator Plus leverages stainless in the shell, discharge bowl, shaft, coupling, wear ring, and suction screen, ensuring the primary wetted parts stand up to harsh chemistry. That’s why I choose stainless in nearly every residential private well application—especially for long set depths where pull-and-replace is labor-heavy and expensive.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
Sand acts like sandpaper in a pump. Teflon-impregnated staging creates a low-friction, self-lubricating interface between impellers and diffusers. On the Myers Predator Plus, the self-lubricating impellers reduce wear as fines pass, maintaining the edge profile and spacing that produce head efficiently. The materials also tolerate brief episodes of dirty water, such as after heavy irrigation drawdown. While no pump thrives on sand forever, this design slows the erosion that leads to flow loss and poor shut-off head. Add proper well development and screens, and you’ll see a meaningful lifespan increase compared to standard composite staging. In the Delgados’ case, seasonal grit after monsoon storms previously chewed up impellers; the Predator Plus design will resist that abrasion much better, keeping their 10 GPM performance stable.
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
Two factors: thrust handling and electrical efficiency. A submersible motor must absorb axial loads from the multi-stage pump stack. The Pentek XE motor is engineered for high thrust, meaning it tolerates stage pressure without bearing failure. Electrically, the windings, rotor design, and thermal overload protection optimize torque at lower amperage draw, especially at 230V. Built-in lightning protection helps survive spikes that take out lesser motors. Efficiency shows up as cooler operation and longer life, particularly when the pump runs near BEP. Field translation: fewer nuisance trips, steady pressures, and lower energy bills. I pair XE motors with staged Predator Plus hydraulics because they complement each other; horsepower gets turned into water at pressure, not wasted as heat.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor?
Capable DIYers can install with the right tools, safety practices, and understanding of local code. However, for wells deeper than 150 ft or where trenching, electrical, and pitless adapter work are required, a licensed pro is smart money. At minimum, you’ll need: lifting gear, 1–1/4" drop pipe, stainless clamps, wire splice kits (adhesive heat-shrink), a torque arrestor, safety rope, and a properly sized pressure tank and pressure switch. Verify voltage, breaker size, and wire gauge to control voltage drop. A contractor brings pull rigs, splice experience, and test instrumentation—helpful for setting correct precharge and verifying performance against the pump curve. If you DIY, PSAM will set you up with the correct Myers kit and accessories and I’ll review your sizing by phone or email.
8) What’s the difference between 2-wire and 3-wire well pump configurations?
A 2-wire pump integrates the start capacitor/relay in the motor can—fewer topside parts, faster install, and fewer external failure points. A 3-wire pump moves those parts to an external control box, making diagnosis and replacement easier without pulling the pump. Performance can be equivalent if the horsepower and hydraulics are matched correctly. For many homeowners, 2-wire at 230V is ideal for simplicity and reliability. For service-heavy locations, rental properties, or marginal power supplies, 3-wire’s serviceability appeals. Myers Predator Plus offers both, so pick based on how you want to maintain the system. Either way, add a surge protector and verify amperage draw at startup and run—clean power keeps motors healthy.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance?
In my field experience, 8–15 years is a realistic range, with well-cared-for systems running 20+ years. Key factors: correct TDH and GPM sizing near BEP, adequate pressure tank volume to prevent short cycling, correct voltage and conductor sizing to minimize drop, and smart materials (stainless and Teflon-impregnated staging). Annual checks—tank precharge, switch contacts, amperage verification, and leak inspection—extend life. In sandy or aggressive water, Myers’ materials buy you extra time before efficiency loss shows up. Compare that to budget thermoplastic pumps that often fail within 3–5 years due to worn stages, bearing failure, or housing cracks. With the Predator Plus and a good install, you’re building in years of service rather than months of luck.
10) What maintenance tasks extend well pump lifespan and how often should they be performed?
Annually: check pressure tank precharge (2 PSI below cut-in), inspect the pressure switch points, verify ground bonding, and confirm amperage draw is within motor spec at typical flow. Every 2–3 years: examine drop pipe and well cap if accessible; look for leaks at the tank tee and test relief valve. After major storms: confirm surge protector health and switch stability. Keep an eye on water clarity and pressure fluctuations; new grit or cycling signals developing issues. If you are irrigating heavily, consider staging zone run times to avoid deep drawdowns. And document everything—model, stages, install date. With Myers, parts are available and the threaded assembly simplifies repair if performance trends down years later.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers provides an industry-leading 3-year warranty on the Predator Plus Series that covers manufacturing defects and performance issues. Many competing submersibles carry only 12–18 months of coverage, and budget brands often just 1 year. I’ve seen this make the difference between a routine service call and an unexpected major expense. Combined with PSAM’s responsive support and parts availability, you get meaningful protection through the pump’s early life—where infant failures, if any, appear. Warranty doesn’t cover abuse, mis-sizing, or improper installation, so correct TDH sizing, proper pressure tank setup, and electrical compliance matter. In practice, Myers’ coverage reduces risk and ownership cost—exactly why I specify it for families like the Delgados.
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Upfront, a Myers Pump may cost more than budget thermoplastic options. Over 10 years, the math flips. With typical budget pumps failing in 3–5 years, you’re buying and installing two to three units—plus dealing with downtime, emergency labor rates, and higher kWh from lower efficiency. Myers’ 80%+ hydraulic efficiency near BEP, Pentek XE motor, and stainless hydraulics cut energy use by up to 20% annually and avoid repeat replacements. Add a 3-year warranty and field serviceable design that allows staged repairs, and lifecycle costs drop dramatically. For a 1 HP, 10 GPM residential setup, I routinely see Myers save $800–$1,500 over the decade compared to budget units—more if a high-head well is involved. Reliability that keeps your family’s water on is, quite literally, priceless.
Final Sizing Notes and a Quick Recap
- Define actual GPM demand with a fixture audit. Calculate accurate TDH: lift + PSI-to-feet + friction. Select a Myers Predator Plus model with your point near BEP. Choose 2-wire or 3-wire based on service preference. Prioritize 300 series stainless steel and Teflon-impregnated staging. Right-size your pressure tank and set your pressure switch intentionally. Install meticulously: drop pipe size, splices, torque arrestor, pitless adapter alignment. Leverage Myers’ 3-year warranty, field serviceable design, and PSAM’s fast shipping and technical support.
