A cold shower, then a hard stop. The kitchen tap coughed air, the laundry stalled mid‑cycle, and the pressure gauge sat flat at zero. That’s how most well emergencies start: not with a warning light, but with silence when you need water the most. Here’s the blunt truth I’ve seen for decades—if you don’t size the pump for both flow and head, you invite early failure, poor pressure, and sky‑high utility bills.
Two nights ago, the Ribera family near Laramie, Wyoming lived that nightmare. Diego Ribera (39), a licensed electrician, and his spouse, Hana (37), a nurse working night shifts, rely on a 380‑foot private well for their rural home and a handful of goats. Their previous 1 HP Red Lion submersible cracked at the housing seam after repeated pressure cycles and grit exposure. With two kids (Marco, 9; Lila, 6), school lunches to prep, and livestock to water, they needed water restored fast—and sized right this time.
In this guide, I break down exactly how to match flow rate to pressure (head), simplify horsepower decisions, and choose the right Myers Predator Plus model for the job. We’ll cover stainless steel durability, motor efficiency, 2‑wire vs 3‑wire decisions, pump curves, total dynamic head math, and more. We’ll also show how Diego and Hana moved from “no water” to a right‑sized Myers system that handles their depth and daily demand without breaking a sweat.
Here’s the roadmap:
- Item 1 explains why materials and staging dictate lifespan and pressure. Item 2 shows how to read pump curves and calculate real‑world total dynamic head. Item 3 simplifies horsepower and staging choices for common depths. Item 4 covers motors, efficiency, and cutting energy costs without losing pressure. Item 5 breaks down 2‑wire vs 3‑wire—what actually matters on site. Item 6 details installation components you must get right for stable pressure. Item 7 maps typical household GPM needs to the right Myers Predator Plus. Item 8 shows how to beat grit and sand problems before they beat your pump. Item 9 compares Myers to Franklin, Goulds, and Red Lion where it counts. Item 10 gives a field‑tested start‑up checklist and maintenance cadence.
Awards and proof? Myers brings an industry‑leading 3‑year warranty, 80%+ efficiency near BEP, and U.S. Manufacturing under Pentair’s R&D umbrella—all UL/CSA certified. At PSAM, I curate Rick’s Picks so you get proven models, same‑day ship on in‑stock pumps, and real sizing help. If you depend on well water, this is the playbook.
#1. Myers Predator Plus Series Stainless Steel Construction - 300 Series Lead-Free Build, Teflon-Impregnated Staging, and Real Pressure at Depth
When water has to rise 200–400 feet, flimsy housings and soft impellers turn into pressure loss, vibration, and early failures. Structure, staging, and materials decide whether you hit target PSI year after year.
Here’s what sets the Myers design apart. The Predator Plus is a submersible well pump built around 300 series stainless steel from shell to suction screen—no shortcuts. Inside, Teflon-impregnated staging uses self-lubricating, engineered composite impellers that stay dimensionally stable in grit and micro‑silt. That stability keeps clearances tight, staging efficient, and pressure consistent. The diffuser and wear surfaces resist scoring, which means less drag, less heat, and fewer amp spikes under load.
For Diego and Hana’s 380‑foot well, stainless and composite staging weren’t just talking points—they were the difference between living with chronic pressure sag and maintaining steady 55–60 PSI inside the home, showers and laundry running at once.
Stainless Where It Counts
When you’re pushing hard against high head, corrosion eats performance first. Stainless fights iron, acidic pH, and mineral‑rich water so your pump stays efficient and quiet over time. Less scaling on wear rings equals cleaner flow paths, and that equals pressure you can feel at fixtures.
Staging That Doesn’t Quit
Stage count produces head. Composite impellers with Teflon impregnation limit abrasive wear, so the pump’s “as‑new” head stays closer to nameplate longer. Expect fewer nuisance callbacks and longer intervals between pull jobs.
Key takeaway: Structure is pressure. Myers builds for head, not hope—exactly what deep and mid‑depth wells demand.
#2. Flow Rate vs Head—Reading a Pump Curve - Matching GPM Rating to TDH and Your Home’s Best Efficiency Point (BEP)
Confused by pump curves? You’re not alone. Matching flow to pressure means reading the curve where your GPM rating, TDH (total dynamic head), and best efficiency point (BEP) intersect.
Start with TDH. Add static lift (water level to tank), friction loss in drop pipe and house plumbing, plus your desired pressure in feet (PSI × 2.31). Example: Diego’s static level sits around 320 feet; adding 50 PSI target (= 115 feet) and 10–15 feet in friction/valves puts his TDH near 445–450 feet at 8–10 GPM. The right Predator Plus model places that duty point near its BEP—where hydraulic efficiency tops 80%, heat stays low, and motors sip amps.
A curve read right means fewer problems: stable pressure during irrigation overlap, less cycling against the pressure switch, and reliable shower flow with the washer running.
How to Calculate TDH, Quickly
- Static level: measure or pull well log. Add 2.31 feet per desired PSI (50 PSI ≈ 115 feet). Add 10–20 feet for fittings/pipe length. Now pick a pump that produces your target GPM at that TDH—on the curve, not at shut‑off.
Why BEP Protects Your Wallet
Running near BEP cuts energy costs and heat load. That’s longer bearing life, fewer nuisance trips, and quiet, steady pressure in the home. It’s how you make a pump pay for itself.
Bottom line: Curves aren’t theory—they’re your blueprint for the right Myers model the first time.
#3. Getting Horsepower Right - Sizing 1 HP vs 1.5 HP with Stages for Real-World Shut-Off Head and Reserve
Undersize a pump and you starve showers; oversize it and you chew up motors and cyclers. The balance comes from horsepower paired to stage count and desired shut-off head.
In the Predator Plus line, a 1 HP model can be excellent for 160–260 feet TDH at 10–12 GPM. Jump to 1.5 HP when TDH exceeds ~300 feet at 10 GPM or when you want reserve for seasonal drawdown. Reserve matters because your static level moves—hot summers can sink it by 20–60 feet. With the right staging, Myers lets you sit comfortably below shut‑off head while staying on the efficient portion of the pump curve.
For the Ribera home, a 1.5 HP Predator Plus staged for 10–12 GPM at ~440–460 feet TDH keeps house and small livestock taps pressurized without flirting with shut‑off. That “headroom” is what ends late‑night troubleshooting.
Stages Build Pressure
More stages equal more head—simple as that. Myers balances impeller geometry so each stage contributes predictable lift without cavitation or runout. Match the stage count to your TDH plus margin.
Reserve for Drawdown
No well is static. Plan 10–15% extra head at your target GPM for seasonal dips, filter changes, and minor expansion (like a future garden zone). It’s cheaper to size once than pull a pump twice.
Pro tip: When in doubt between models, choose the curve that places your duty point at or just left of BEP. That’s long‑game thinking.
#4. Motors and Efficiency - Pentek XE High-Thrust Motor, 230V Single-Phase, and Real-World Energy Savings
Motors are where pumps quietly win or lose. Myers couples Predator Plus hydraulics to the Pentek XE motor, a high‑thrust, 230V single‑phase design with strong starting torque, smooth running amps, thermal overload protection, and integrated surge hardening.
Here’s why that matters: high thrust handles axial loads from multi‑stage impellers under head. Efficient windings and rotor design keep heat low at duty point, protecting insulation and bearings. Under lightning‑prone conditions common in the Mountain West and Plains, voltage transients are less likely to finish an otherwise healthy pump.
For Diego and Hana, an efficient motor shaved peak amps during irrigation overlap and cut kWh draw by an estimated 15–20% versus their previous unit—while delivering higher head at the same GPM.
Why Efficient Motors Last
Cooler operation preserves varnish, reduces bearing wear, and prevents nuisance trips. Pair that with stainless hydraulics and you get 8–15 year service windows—often longer with good water chemistry and maintenance.
Match Motor to Curve
Choose the motor that holds your duty point in its sweet spot. Oversized motors cycling at short intervals kill savings; right‑sized motors running near BEP are quiet and cheap to run.
Recommendation: For most deep residential wells, 230V is the cleanest path to stable starts and lower line loss.
#5. Wiring Made Simple - 2-Wire Well Pump vs 3-Wire Well Pump, Control Boxes, and Real Install Choices
Electrical configuration changes installation time and future troubleshooting. Myers offers both 2-wire well pump and 3-wire well pump options across Predator Plus models, so you can choose the right setup for your depth and service preferences.
A 2‑wire integrates the start components within the motor—fewer parts on the wall, fewer connections to corrode, and faster replacements. A 3‑wire moves the start cap/relay to a control box topside—handy for diagnostics, preferred by some contractors on very deep or complex systems. Myers gives you real options either way without locking you into proprietary controls.
For the Ribera system at ~440–460 feet TDH, we specified a 3‑wire Predator Plus to give Diego easy access to start components at the panel. If Hana calls while he’s on a job, remote diagnostics are simpler with a box on the wall.
When 2-Wire Wins
Shorter installs, fewer points of failure in damp pump rooms, and cost savings on control gear. For wells under ~250 feet TDH, I often recommend 2‑wire Myers models for DIY‑friendly swaps.
When 3-Wire Shines
Deeper wells, complex systems, or clients who want quick diagnostic access. With Myers, you’re not paying a “brand tax” to change configurations, just choosing the smarter fit for the site.
Either way, you get the same stainless hydraulics and XE motor pedigree. That’s why I stock both at PSAM.
#6. The Installation Backbone - Pressure Tank, Pressure Switch, Check Valve, and Pitless Adapter Done Right
Hydraulics get headlines, but controls and fittings keep pressure steady. Undersized or worn parts make even a premium pump look bad. Build the backbone right.
Start with the pressure tank and pressure switch. Correct drawdown volume cuts cycling; accurate switch differentials prevent rapid on/off that hammers motors. Add a top‑quality inline check valve above the pump if code or site demands it, but never stack multiple checks through the drop—water hammer city. A clean pitless alignment keeps torque forces centered; a sturdy pitless prevents leaks at the wall in freeze/wind‑load zones.
In the Ribera install, a larger tank and properly set 40/60 switch stabilized run times. One high‑quality check at the pump and good alignment through the pitless stopped the nightly “bang” Diego heard with the old system.
Friction Loss Is Head
Tight elbows, undersized drop pipe, and crusty fittings add feet of head you didn’t plan for. Use sweep fittings, right‑sized pipe, and take the win on efficiency.
Protect the Wire Splice
A clean, heat‑shrinked, double‑walled splice with adhesive lining isn’t optional—it’s survival. Keep it above the pump, strain‑relieved, and guarded. Electrical failures look like hydraulic problems on day one.
Do the small things right and your Myers keeps its promise: quiet, steady pressure for years.
#7. How Much Water Do You Really Need? - Household GPM, Irrigation Overlap, and Picking the Right Myers Curve
Most homes need 6–10 GPM for comfortable living; add irrigation overlap or livestock and you’re into 10–14 GPM territory. The art is supplying that flow without sacrificing pressure at depth.
Match the home’s fixture count, simultaneous use, and any irrigation zones to a GPM rating that holds at your TDH. For a family of four with a modest garden, 10 GPM is typically perfect. For multi‑zone irrigation, consider 12–15 GPM or plan staggered watering to keep head stable.
Diego wanted a dependable 10–12 GPM while his goats’ trough autofilled. We sized the Predator Plus model that delivers that flow at ~450 feet TDH, right at its curve sweet spot—no “wheezing” when the washer and shower run together.
Irrigation Strategy
If you need 15+ GPM but your well is deep, stagger zones by timer. Let domestic water rule; let the yard take turns. It’s usually cheaper than upsizing to a bigger motor and higher electric bills.
Future-Proofing
Plan for a bathroom addition or a small shop sink? Add 10–15% to your target flow or stage selection. Reserve capacity costs little now and saves a pull later.
With PSAM, I’ll put your fixture and irrigation list against the curves and give you the right Myers pick—no guesswork.
#8. Fighting Sand and Grit - Intake Screens, Composite Impellers, and Operating Near BEP to Reduce Wear
Abrasives destroy clearances, score bowls, and hike amperage. Myers fights back with robust intake screening, engineered diffusers, and composite staging that shrugs off micro‑silt. Pair that with operation near BEP and you cut internal turbulence that “sandblasts” stages.
If your well produces fine grit seasonally, avoid overspeeding the hydraulics. Pumps run far right of their curves can churn sediment and scour internals. A correctly sized Predator Plus keeps velocity where it belongs—moving water efficiently without stirring the bottom of the well.
The Ribera well kicks up grit during late summer drawdown. The Myers staging handled the fines without chewing itself to pieces, and by keeping the duty point at BEP we reduced abrasive attack from inside the bowls.
Screen and Set Depth
Use the factory intake screen, verify set depth above known silt layers, and keep the pump off the bottom. More distance above the screen horizon equals cleaner water.
Filters After the Tank
Sediment filters belong after the pressure tank, not before the switch. Starving the pressure switch with a clogged pre‑filter creates cycling chaos.
Do abrasives right and you’ll see Myers’ durability advantage compound year after year.
#9. Real-World Brand Comparison - Franklin Electric, Goulds Pumps, and Red Lion vs Myers Predator Plus Under Pressure
Let’s compare where it matters for flow, head, and long‑term cost.
Technical performance: Myers Predator myers sewage pump submersible Plus uses all‑ 300 series stainless steel in wet‑end construction, composite bowls, and Teflon-impregnated staging for abrasion resistance, mated to the Pentek XE motor for stable thrust and low heat near BEP. Franklin Electric submersibles are solid performers but often pair with brand‑specific control components. Goulds Pumps employs cast iron in some assemblies that can corrode in aggressive water. Red Lion’s thermoplastic housings keep costs down but don’t love high head and frequent pressure cycling.
Applications and maintenance: Myers’ field‑friendly build and threaded assembly allow straightforward service, especially valuable for rural installs without a proprietary dealer in range. Stainless construction wins in mineral‑rich and slightly acidic wells. Self‑lubricating staging reduces the grit‑induced wear that sends many pumps to early retirement. In my files, Myers installs consistently deliver 8–15 years with routine care, while budget thermoplastic units average 3–5 in similar conditions.
Value proposition: If you depend on a private well, downtime costs more than hardware. With stainless construction, XE motors, PSAM stocking, and a rock‑solid 3-year warranty, Myers delivers lower lifetime ownership and fewer emergency Saturday pulls—worth every single myers shallow well pump penny.
Diego and Hana’s Outcome
Replacing a cracked Red Lion unit with a Predator Plus 1.5 HP model restored 10–12 GPM at ~450 feet TDH. Energy use dropped, pressure stabilized, and they regained normal life—showers, laundry, and goats included.
#10. Start-Up, Warranty, and Service - Factory-Tested, UL/CSA, and the 3-Year Safety Net That Actually Protects You
Even the best pump deserves a careful start‑up. Myers ships factory tested, UL listed and CSA certified units with clear start procedures: fill the system slowly, purge air, verify switch settings, and log amperage at steady state. Keep that record with your serial number—warranty gold.
Speaking of protection, Myers’ industry‑leading 3-year warranty is real coverage, not a brochure line. When matched to Pentair engineering support and PSAM stocking, you’ve got protection for manufacturing defects and performance issues that outclasses most of the field.
For the Riberas, documenting static level, pressure switch settings, running amps, and initial flow gives us a solid baseline. If something drifts, we’ll know why—and fix, not guess.
Maintenance Cadence That Works
- Annual: test switch cut‑in/cut‑out, check drawdown, inspect wiring, clean filters. Biannual in grit wells: flush sediment filters, inspect for pressure decay. After lightning: check amp draw and insulation resistance if available.
Do this, and a Predator Plus will easily hit its 8–15 year expectation—with many owners seeing 20+ years of service.
Detailed Comparative Notes (Deployed Across the Guide)
- While Franklin Electric submersibles often pair with proprietary or brand‑specific control boxes and service networks, Myers Predator Plus provides a flexible, field serviceable setup with threaded assemblies and contractor‑friendly diagnostics. In remote regions, that means faster repairs without waiting on a dealer queue. Coupled with the Pentek XE motor and stainless wet end, Myers holds its curve performance under load and resists water chemistry that eats lesser metals. For homeowners depending on well water day in and day out, the combination of easy serviceability, durable materials, and high efficiency is worth every single penny. Unlike Goulds components that include cast iron in certain models—vulnerable to corrosion in acidic or high‑iron wells—Myers’ all‑ 300 series stainless steel shell, shaft coupling, and screen maintain flow paths and resist scaling. Where Goulds may require more frequent internal cleaning in problematic water, the Myers staging stays cleaner, longer. Add in factory UL/CSA certification, a robust 3-year warranty, and PSAM’s same‑day shipping, and you have fewer interruptions, fewer emergency calls, and predictable ownership costs—worth every single penny. Compared to Red Lion’s thermoplastic housings that fatigue under repeated high‑head cycling, Myers builds for pressure with stainless shells and engineered diffusers that hold geometry at depth. That means your target PSI at the sink survives summer drawdown and winter demand. For homeowners who’ve suffered two‑year replacement cycles on budget pumps, a Myers Predator Plus that runs efficiently near BEP and shrugs off grit is worth every single penny.
FAQ: Field-Tested Answers from Rick
1) How do I determine the correct horsepower for my well depth and household water demand?
Start by calculating TDH (total dynamic head): static water level in feet + desired PSI × 2.31 + friction loss (10–20 feet for typical homes). Then choose a pump whose pump curve delivers your required GPM at that TDH near BEP. Example: If your static is 220 feet and you want 50 PSI (≈115 feet) with ~10 feet friction, TDH ≈ 345 feet. For 10 GPM at 345 feet, a Predator Plus around 1–1.5 HP is typically right, depending on staging. For 6–8 GPM at shallower TDH (under 250 feet), 1 HP often suffices. My recommendation: share your TDH and target GPM with PSAM; I’ll put your numbers on the curve and confirm the correct HP and stages so you don’t overspend or undershoot pressure.
2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
Most homes function well at 6–10 GPM. Add irrigation overlap or livestock and you’re closer to 10–14 GPM. Multi‑stage impellers stack pressure; each stage adds head. In the Myers Predator Plus, staging geometry and close tolerances maintain head under load with minimal recirculation. If you need 10 GPM at 320 feet TDH, pick a model whose curve shows that duty point comfortably left of center (near BEP). More stages = more head capacity; the right stage count prevents running at the ragged edge (near shut-off head) that risks heat and wear.
3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
Efficiency comes from precise hydraulic geometry, tight staging clearances, and the Pentek XE motor running the impellers in their sweet spot. Operating near BEP reduces turbulence and internal slip, translating into 80%+ efficiency on the right duty points. Pair that with stainless components that resist scaling and you maintain efficiency longer. Result: lower amperage at set pressure, cooler operation, and real‑world savings. In side‑by‑side installs, I routinely see 15–20% kWh reductions vs. Older or budget units at the same head.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps?
Below the waterline, cast iron corrodes in aggressive chemistry and scales in mineral‑rich wells. 300 series stainless steel shrugs off staining and pitting, keeps clearances close, and preserves flow paths. That’s head you don’t lose to rust and drag. In my service logs, stainless wet ends in Myers outlast mixed‑metal builds, especially past the five‑year mark where corrosion usually starts robbing pressure.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
Teflon-impregnated staging uses engineered composites that maintain shape under abrasion and heat. The self‑lubricating property minimizes friction where fines try to grind clearances. Compared to traditional plastics, this composite holds geometry far longer in sandy wells, preserving head and lowering amp draw. Pairing this with correct set depth and avoiding bottom churn keeps your pump’s internals looking almost new after seasons of use.
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
The Pentek XE motor uses optimized windings, robust thrust bearings, and rotor design tuned for multi‑stage axial loads. High starting torque, smoother running amps, and thermal overload protection deliver steady performance under deep‑well head. By holding current closer to nameplate at duty point, the XE keeps heat down and efficiency up—directly translating to longer life and lower bills.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor?
Many competent DIYers replace a submersible well pump safely with the right tools, a helper, and caution. That said, deep wells, 3‑wire control diagnostics, and pitless work can justify a contractor. The Predator Plus is field serviceable with threaded assembly, making on‑site repairs practical. If you DIY, use torque arrestors, secure splices with adhesive heat‑shrink, and verify switch settings before power‑up. PSAM can supply a complete kit and phone guidance.
8) What’s the difference between 2-wire and 3-wire well pump configurations?
A 2-wire well pump has internal start components—simpler install, fewer wall parts, faster swaps. A 3-wire well pump uses an external control box—easier diagnostics and preferred on some deeper or complex systems. Performance at the hydrant is the same when the curve and HP match. Myers supports both, so you choose what fits your site and service preference.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance?
With good water chemistry and annual checks, 8–15 years is typical, and I’ve seen 20+ on well‑kept installs. Protect against rapid cycling, keep filters clean (post‑tank), and maintain correct switch settings. Stainless construction and composite staging resist the slow losses that force early replacements.
10) What maintenance tasks extend well pump lifespan and how often should they be performed?
- Annually: test pressure switch cut‑in/out, inspect the pressure tank drawdown, check amperage at duty point, flush filters. Seasonally in sandy wells: inspect for pressure drops, consider a camera check at major drawdowns. After storms: verify surge protection and listen for bearing noise. These small steps keep you near BEP, reduce heat, and increase lifespan.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers’ 3-year warranty outstrips the typical 12–18 months you see elsewhere. It covers manufacturing defects and performance failures under normal use, backed by Pentair’s support network and PSAM’s documentation help. Log your start‑up readings and keep receipts—if something does go wrong, you’ll have the paperwork to move quickly.
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Budget thermoplastic pumps can cost less at checkout, but frequent replacements (every 3–5 years) add labor, downtime, and energy waste. A properly sized Predator Plus running 80%+ efficient near BEP usually wins the 10‑year math—fewer pulls, lower kWh, and stable pressure. Factor in the 3-year warranty, stainless durability, and XE motor efficiency; the long‑term curve bends decisively toward Myers.
Conclusion: Flow, Head, and the Myers Advantage—Sized Right, Built to Last
Flow without pressure is useless. Pressure without flow is frustration. The Predator Plus line from Myers balances both with stainless construction, durable composite staging, and the Pentek XE motor driving efficient curves—right where real homes live. You get flexible wiring choices, proven field serviceability, and an industry‑leading 3-year warranty that actually means what it says.
The Ribera family went from zero water to steady 10–12 GPM at roughly 450 feet TDH by matching their needs to the correct pump curve, staging, and controls—no drama, no guesswork.
