A silent house is a bad sign. No hum from the pressure switch, the shower sputters, and by the time the coffee maker calls for water—nothing. For private well owners, a power outage doesn’t just mean lights out. It means toilets don’t refill, livestock goes thirsty, and laundry stops mid-cycle. I’ve seen it hundreds of times on service calls, and the preventable part is always the same: no backup power plan matched to the well pump.
Two Saturdays ago, the Peraltas—a new family in my service area—hit this wall. Carlos Peralta (38), a high school math teacher, and his spouse, Ana (36), a nurse, moved with their kids Mateo (9) and Lila (6) to eight acres outside Cortland, New York. Their 220-foot private well with a 1 HP, 10 GPM system had been fine until a late-spring storm cut grid power for 18 hours. Their previous pump, a budget model from a big box, failed last year after grit chewed up the impellers. The replacement—a Myers Predator Plus Series 1 HP paired with a Pentek XE motor and Teflon-impregnated staging—has been flawless. But without backup power, flawless doesn’t pump water.
This guide walks you through the 10 decisions I use to size and install backup power that plays perfectly with Myers water well pumps, with a focus on the Predator Plus submersible line. We’ll calculate starting loads, choose generator and battery geometry, address surge and harmonics, prevent control box surprises, and protect the system with proper switching. Along the way, I’ll show how the Peraltas landed on the right setup, why the Myers design makes backup easier, and how you can avoid the classic, costly mistakes.

Awards, achievements, and why it matters: Myers Pumps, backed by Pentair, deliver 80%+ hydraulic efficiency near BEP and an industry-leading 3-year warranty. With 300 series stainless steel construction, field serviceable threaded assembly, and Made in USA consistency, they’re engineered for the long haul. As PSAM’s technical advisor, I curate “Rick’s Picks” to keep these installs clean, code-compliant, and worry-free. My goal here isn’t hype. It’s an on-the-ground, do-this-right-first-time blueprint, built around what works in storms, ice, and heat waves.
#1. Know Your Starting Surge – Calculating Inrush for 1/2–2 HP Myers Submersibles Using BEP and Pentek XE Motor Characteristics
Backup power succeeds or fails on startup surge. A multi-stage pump may run at 1,100–1,500 watts, yet demand 3–5x that for milliseconds at startup.
The Pentek XE motor used on Myers submersible well pump models is designed with high-thrust bearings and efficient windings that pull lower inrush than commodity motors. Typical 1 HP, 230V submersibles with clean power see 6–8 amps running at load (1,300–1,800W), with inrush peaking 30–40 amps for a fraction of a second. At steady-state near best efficiency point (BEP), a Predator Plus 10 GPM stack operates at 80%+ hydraulic efficiency, so real-world watt draw is often lower than the “rules of thumb” from big-box charts. Still, size backup for worst case: deep head, cold water, full pressure rise.
The Peraltas’ 1 HP Myers holds system pressure at 50–60 PSI with a 44-gallon tank. We measured running draw at 1,420W and a surge that briefly touched 6,800–7,200 VA on a clamp meter with inrush capture. That data drove our generator and inverter spec.
Determine Surge the Right Way
Use a meter with inrush capture on a normal start cycle. If you can’t, multiply running amps by 3.5–5x for surge estimation. Consider TDH lift, friction loss, and pressure setpoint. Higher TDH pushes running amps up. Build 20–30% headroom into generator/inverter specs for summer heat, aging windings, and voltage sag.
Why BEP Matters in Backup
Operating near BEP stabilizes current draw, eases startup, and reduces heat. Myers’ curve data lets you choose staging to align with demand. Oversizing the pump increases watt draw and surge. Right-size horsepower, save fuel and cash.
Rick’s Takeaway
Document surge before you buy backup. For most 1 HP Myers, target backup capable of delivering 7–8 kVA for clean starts.
#2. Choose the Right Generator – 230V Split-Phase Output, THD Under 5%, and Ample kW for Myers Predator Plus
A 230V submersible on a single-phase motor expects clean sine power. Cheap open-frame units with high THD distort waveforms and stress insulation. Look for inverter generators or premium alternators rated under 5% THD.
For a 1 HP Myers, I specify 6–7 kW continuous with at least 9–10 kVA surge. That gives cushion for the pump plus fridge/freezer and control loads without significant voltage sag. A 1.5 HP pump typically needs 8–9 kW continuous with 12–14 kVA surge.
The Peraltas went with a 7.5 kW inverter generator, 240V capable, bonded neutral, and automatic idle disabled for cleaner starts. Result: smooth startups, no nuisance trips, and stable pressure cycles.
Voltage, Frequency, and Harmonics
Maintain 230V ±5% and 60 Hz. Frequency drift can increase motor temperature and reduce thrust bearing life. Keep THD <5% for submersible motors; <3% is ideal. </ul> Receptacle and Breaker Strategy Use a 30A or 50A 240V twist-lock depending on unit rating. Protect with a 2-pole breaker sized for motor and other essential loads. Don’t cheat on wire gauge; 10 AWG copper for 30A is the minimum.
Fuel Burn Reality Expect 0.5–0.8 gallons/hour at light household load, 1+ gallons/hour with well cycling and appliances. Plan fuel storage accordingly.
Rick’s Takeaway A 7–9 kW low-THD generator is the sweet spot for most 1 HP Myers installations. Quality power in equals long motor life out. #3. Battery Backup and Inverter Hybrids – When a 48V System Makes Sense for a 10 GPM, 230V Submersible Battery backup protects water access at night or when fueling is risky. Website link The catch? Starting a deep well pump off batteries requires a robust inverter with high surge capacity. Think 48V, 6–12 kW inverter/charger with 2–3x surge for a few seconds. A 1 HP submersible isn’t an easy battery load. The right hybrid inverter plus generator auto-start solves it: the inverter handles steady power and short surges; the generator kicks in if runtime or surge exceeds limits. For the Peraltas, I set a 48V, 8 kW hybrid inverter with 16 kWh of LiFePO4. It carries the Myers pump, lights, and router for several hours. If outage stretches, the generator autostarts to recharge. Sizing the Battery Bank Aim for 2–4 hours of domestic duty: 6–10 pump cycles/hour at ~1–3 minutes per cycle. For a 1 HP pump averaging 1.4 kW during run, 16 kWh gives a safe buffer with other loads considered.
Inverter Specs That Matter Surge: At least 2.5x continuous rating for 5 seconds. Split-phase 120/240V output. Charger current strong enough to recover battery in 2–4 hours with generator assist.
Rick’s Takeaway Battery backup works if surge is solved and runtime is realistic. Pair a stout inverter with a right-sized generator for a seamless system. #4. 2-Wire vs 3-Wire Under Backup Power – Control Boxes, Starting Circuits, and Myers Compatibility Backup power shines brighter when startup is simple. A 2-wire well pump integrates the start components in the motor; a 3-wire well pump uses an external control box with start capacitor and relay. Both work on generators and inverters, but 2-wire simplifies installation and eliminates one failure point. Myers offers both options. For many homes, I recommend 2-wire up to 1 HP for reduced complexity, especially on backup systems. Where heads are deeper or where diagnostic access is valuable, 3-wire with a quality control box is fine. The Peraltas’ 1 HP Myers is a 2-wire, which made their transfer setup cleaner—fewer boxes to protect, fewer harmonics issues, one less enclosure to winterize. Starting Behavior Differences 2-wire: Clean, integrated start; slightly higher inrush in some cases; fewer connections to fail. 3-wire: External components are serviceable; start capacitors can be upsized if needed for tough starts (with manufacturer guidance).
Supply Voltage and Leads Confirm 230V configuration and wiring integrity all the way to the pressure switch, tank tee, and drop-pipe splice.
Rick’s Takeaway If you’re planning backup power, a Myers 2-wire is often the easiest, most reliable path—simple, robust, and generator-friendly. #5. Transfer Switches, Interlocks, and Neutral Bonding – The Safe, Code-Compliant Way to Power a Well Circuit No shortcuts here. An improper backfeed can injure a lineman or fry your control box and motor. Use a listed transfer switch or panel interlock that switches both hot legs and respects neutral bonding. For the Peraltas, we installed a 30A, 240V manual transfer switch feeding a subpanel: well pump, refrigerator, lighting, and internet. The generator’s neutral is bonded at the unit; we opened the service bonding screw per code using a switched neutral kit. Always follow local codes and manufacturer instructions. Switching Options Whole-house automatic transfer switch: seamless, but more costly. Manual interlock kit: economical; ensure the main and generator breakers cannot be on simultaneously. Dedicated well circuit transfer switch: simplest for pump-only backup.
Grounding and Surge Devices Install UL listed surge protection at the panel and on the well circuit. Bond the well cap, casing, and panel ground.
Rick’s Takeaway Get the switching right the first time. Safe, code-compliant transfer preserves your pump warranty and keeps everyone safe. #6. Bigger Pressure Tank, Smaller Generator – Using Drawdown to Reduce Start Cycles and Fuel Burn A well-sized pressure tank is backup power’s best friend. More drawdown means fewer pump starts per hour, which saves generator fuel and reduces stress on windings and bearings. Rule of thumb: design for 1–2 starts per hour under backup power. That usually means at least 2–3 minutes of runtime per cycle and generous drawdown at your pressure setting. For a 1 HP, 10 GPM system at 40/60 PSI, a tank with ~14–16 gallons drawdown is the starting point; 20–30 gallons is even better. We upsized the Peraltas from a 44-gallon shell to a 62-gallon pressure tank. During outages, the generator runs less often and the pump cycles smoothly. Pressure Switch and Drawdown A 40/60 PSI setting increases drawdown compared to 50/70. Balance shower feel with backup efficiency. Set precharge 2 PSI below cut-in. Check annually.
Piping and Check Valves Use a single, high-quality check valve at the pump or tank tee; avoid stacking checks that can trap pressure and hammer.
Rick’s Takeaway Double your tank drawdown and your generator will thank you. Start cycles, not running watts, are what kill backup plans. #7. Surge, Lightning, and Motor Protection – Shielding Pentek XE Motors and Control Gear from Dirty Power Outages and storms travel together. When grid power returns, voltage sags and spikes chew up electronics. Protect your Myers water pump investment with a layered approach: whole-house SPD, well-circuit SPD, and motor thermal protection. The Pentek XE motor includes thermal overload protection and lightning protection, but external SPDs clamp high-energy transients before they reach windings and the pressure switch contacts. The Peraltas added a Type 2 SPD at the main panel and a DIN-rail SPD in the well subpanel. Their generator has built-in AVR; the inverter outputs low-THD sine. Belt and suspenders. SPD Placement Main service: Type 1 or Type 2 SPD. Well circuit: secondary SPD near the breaker feeding the pump. Bonding: Tie the well casing, panel ground, and any lightning rods to a common grounding electrode system.
Wire and Splices Use a proper wire splice kit with heat-shrink and adhesive. Moisture intrusion is the silent killer.
Rick’s Takeaway Protection is cheap compared to a deep pull job. Stack your defenses and keep the pump curve, not lightning, running the show. #8. Fuel Strategy, Cold Starts, and Maintenance – Keeping Backup Ready for the Long Outage A generator without fuel is just a loud lawn ornament. Plan for at least 48–72 hours of intermittent runtime. Store stabilized fuel, rotate it every six months, and test under load quarterly. Cold weather adds load. Oil thickens, surge rises, and small alternators struggle. I often specify cold-weather kits and keep idle control off during pump starts. The Peraltas keep 25 gallons of stabilized gasoline on hand, with a rotation log taped to the can rack. Their generator gets a 20-minute, full-load test on the first Saturday of every month. When outages hit, they’re not troubleshooting. They’re taking showers. Maintenance Checklist Change oil per hours or annually. Test transfer switch operation under load. Exercise the generator with the pump cycling. Inspect pitless adapter, torque arrestor, and safety rope on scheduled well maintenance intervals, not just when things break.
Rick’s Takeaway Backup power is a system, not a purchase. Fuel, testing, and seasonal prep make the difference between theory and showers. #9. Why Myers Pumps Play Nicer with Backup – Stainless Steel, Teflon Staging, and Field-Serviceable Threaded Assemblies Backup power exposes weak pumps fast. Voltage dips turn marginal bearings and brittle plastics into burned motors and seized impellers. Myers Predator Plus Series solves this with 300 series stainless steel construction—shell, discharge bowl, shaft, coupling, wear ring, and suction screen—and Teflon-impregnated staging that tolerates grit and sand. The threaded assembly design is field serviceable, so your contractor can repair on-site if needed. Carlos had grit in his well after spring runoff. Where budget pumps shred, his engineered composite impellers brushed it off. During backup testing, starts were crisp and amperage stayed stable, even under the 60 PSI setting. Component Quality that Reduces Backup Risk Stainless structure resists flex and creep during hot restarts. Self-lubricating staging keeps current draw predictable. Pentek XE high-thrust bearings handle vertical load without inrush drama.
Rick’s Takeaway When you feed clean power to a well-built pump, you get quiet, predictable starts. That’s the Myers advantage under backup stress. #10. Field-Proven Install Checklist – Everything I Verify Before Calling It Storm-Ready Details win outages. Here’s my list for every Myers well pump backup job: Pump: Correct HP and staging from the pump curve, aligned to TDH and GPM demand Electrical: 230V verified, correct amperage draw, snug splices, drip loops, and strain relief Protection: Dual SPDs, correct breaker sizing, good grounds, dry well cap Plumbing: Proper pressure tank sizing, clean tank tee, one check valve, no leaks Transfer: Listed switch/interlock, labeled circuits, documented neutral bonding Generator/Inverter: Low THD, surge margin proven by live test with pump cycling Fuel/Testing: Stabilized supply, rotation schedule, quarterly runtime under real load Documentation: Pump model, serial, wire gauge, static/dynamic water levels, pressure settings
For the Peraltas, this checklist turned their outage from chaos to manageable. Water kept flowing, and their Myers pump never missed a beat. Rick’s Takeaway If it’s not tested under load, it’s not ready. Simulate the outage now, not at 2 a.m. in freezing rain. Detailed Brand Comparisons You Can Use to Make the Call Compared to Goulds Pumps and Red Lion in real backup scenarios, Myers delivers a measurable edge. Technical performance: Myers’ 300 series stainless steel assemblies resist corrosion, critical when generators return with fluctuating voltage that can accelerate electrochemical wear on mixed-metal pumps. Teflon-impregnated staging keeps impeller clearance stable, so surge and running amps water pump myers don’t drift over time. Pentek XE motors exhibit strong starting torque at lower inrush than many standard motors, which eases generator sizing by 1–2 kVA in some 1 HP setups. Real-world differences: In service calls where Goulds cast components faced acidic water, we saw premature wear and rising startup current—bad news for small generators. With Red Lion’s thermoplastic housings, pressure-cycle fatigue sometimes cracked volutes after a couple of seasons, especially when tanks were undersized and pumps short-cycled during outage tests. Myers systems, by contrast, tolerate grit and heat better, start consistently on inverter generators, and maintain curve performance longer between pulls. Value proposition: For a rural household that must run on backup a few days each year, Myers’ reliability reduces replacement cycles, keeps surge predictable, and safeguards your fuel plan—worth every single penny. Another practical head-to-head—Myers vs Franklin Electric—through the backup lens: Technical performance: Franklin submersibles often tie you to proprietary control boxes and dealer networks. On backup installs, that means one more component to protect and diagnose when power is dirty. Myers Predator Plus uses a field serviceable threaded assembly and offers both 2-wire and 3-wire flexibility, paired with Pentek XE motors that start strong on the low-THD power you’ll get from a quality inverter generator. Hydraulic efficiency near BEP tops 80%, so running watts trend lower, easing inverter sizing. Application differences: A contractor with a truck stock can service a Myers assembly on-site, minimizing downtime when an outage exposes a weak link. Franklin setups sometimes require specific parts and control logic that slow repairs in rural areas. When you’re rationing generator fuel, fewer start retries and stable current draw matter. Value: Between the 36-month 3-year warranty, Made in USA build, and PSAM support, the Myers pump reduces total ownership cost and generator size stress—worth every single penny. Finally, budget brands: Everbilt and Flotec look attractive upfront, but outages are unforgiving. Technical performance: Budget motors and thermoplastic internals struggle with high inrush and heat during repeated starts. Efficiency is lower, so running watts creep higher—adding generator load and fuel burn. Bearings and impellers wear quickly, increasing surge and risking nuisance trips on small generators. Real-world differences: On two sites last winter, Everbilt 1 HP pumps failed within three years—one seized after surge events during an ice storm. Both homeowners upgraded to Myers Predator Plus and immediately saw cleaner starts and reduced generator labor. Value: Over a 10-year window, Myers’ reliability, 3-year warranty, and energy performance beat multiple budget replacements, extra fuel, and emergency labor—worth every single penny. Frequently Asked Questions: Backup Power for Myers Pumps 1) How do I determine the correct horsepower for my well depth and household water demand? Start with your Total Dynamic Head (TDH): static water level + drawdown + friction loss + pressure converted to feet (PSI x 2.31). Cross-reference the TDH and desired flow on the Myers pump curve to select horsepower and stages. A typical 3–4 person household needs 8–12 GPM; a 1/2 HP may handle shallow 60–100 ft TDH, while a 1 HP suits 150–250 ft TDH at 10 GPM. If your home has irrigation or livestock, consider 12–20 GPM using a 1–1.5 HP. Pumps running near BEP draw fewer watts and live longer. My recommendation: document water level recovery, measure actual friction loss (pipe size, length, fittings), and size to land your operating point on the efficient middle of the curve. When in doubt, call PSAM; we’ll run your numbers and match a Myers Predator Plus Series properly. Oversizing wastes energy and increases surge; undersizing invites pressure sag and rapid wear. 2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure? Most homes live comfortably at 8–12 GPM. Showers, laundry, dishes, and a hose bib can overlap, so 10 GPM is the workhorse target. A multi-stage pump stacks impellers to increase head (pressure capability) at a given GPM. More stages shift the curve upward, allowing a deep well pump to meet 50–60 PSI house pressure with margin for friction loss. On a 10 GPM Myers, a 1 HP with the right staging will deliver steady pressure and reduced cycling when paired with a correctly sized pressure tank. For irrigation or large families, consider higher GPM models to avoid long duty cycles. The key is placing your operating point on the pump curve where efficiency is high and NPSH (available) is adequate—less heat, less amp draw, more reliability on both grid and backup power. 3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors? Efficiency comes from precise impeller geometry, engineered composite impellers with Teflon-impregnated staging, and tight clearances maintained by 300 series stainless steel wear components. At the BEP, hydraulic losses are minimized, so for a given head and GPM, watt draw is lower. That translates to smaller generator/inverter requirements during outages. Pairing with a Pentek XE motor reduces electrical losses too—better windings, high-thrust bearings, and optimized starting circuits keep amps controlled. On a 1 HP, 10 GPM system, I routinely measure 1,300–1,600W running at 50–60 PSI, versus 1,700–2,000W for some budget pumps at the same duty. Lower watts per gallon pumped is real money saved and easier backup sizing. 4) Why is 300 series stainless steel superior to cast iron for submersible well pumps? Underwater, metals face minerals, acidity, and galvanic interactions. 300 series stainless steel resists corrosion, pitting, and scale adhesion better than cast iron. It also maintains dimensional stability under thermal cycling—important when backup power causes quick restarts and heat spikes. Cast iron components, as found in some competitor offerings, can corrode in acidic wells and shed oxides that worsen wear inside the staging stack. Stainless construction in the Myers Predator Plus—shell, discharge bowl, shaft, coupling, wear ring, and intake screen—protects tolerances and keeps impeller clearance consistent. Consistent clearance equals efficient pumping and predictable current draw, especially valuable when running on a generator or inverter with finite surge capacity. 5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage? Sand acts like valve grinding compound. Teflon-impregnated staging in Myers pumps creates a slick, wear-resistant interface, so particles pass with minimal abrasion. The self-lubricating impellers keep friction and heat down during micro-contact events. Over time, that means the GPM rating and amperage draw remain stable, extending motor life and easing backup starts. I’ve torn down budget pumps with gouged impeller eyes after one gritty season; the Myers staging, by contrast, shows light polishing but holds shape. If your well sees seasonal sediment, this material difference buys years and keeps your generator from fighting rising inrush as clearances degrade. 6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors? The Pentek XE motor pairs high-grade windings with thrust bearings designed for vertical load, reducing friction and electrical losses. Thermal design sheds heat efficiently, and integrated thermal overload protection safeguards against locked rotor events and brownouts—common during outages. In practice, a 1 HP XE draws fewer watts at the same head and flow than many standard motors, and it starts crisply on low-THD inverter generators. That’s why I can often spec a 7–8 kW generator instead of 10+ kW for a 1 HP setup—surge is tamed, and running watts are honest. 7) Can I install a Myers submersible pump myself or do I need a licensed contractor? You can DIY if you’re comfortable with electrical code, plumbing, and safe well handling. That said, many jurisdictions require permits, and mistakes are expensive 200 feet down. A pro brings a pull truck, hoist, wire splice kit, torque tools, and experience with pitless adapters, check valves, and pressure switch calibration. For backup systems, wiring the transfer switch or interlock and managing neutral bonding is code-critical. My middle-ground advice: let a contractor handle the pull, set, and electrical; you manage trenching, tank pad, and interior plumbing to save labor. PSAM can supply complete kits—pump, drop pipe, wire, tank tee, and switching gear—sized to your well. 8) What’s the difference between 2-wire and 3-wire well pump configurations? A 2-wire well pump integrates the start components inside the motor—fewer parts to mount and protect. A 3-wire well pump locates the start capacitor and relay in a control box above ground, enabling easier service of those parts. Under backup power, both work well, but 2-wire simplifies the system and slightly reduces points of failure. On deeper heads or marginal voltage situations, a 3-wire’s external start components can be tuned with manufacturer-approved parts. For most 1 HP residential systems, I favor 2-wire Myers models, especially when the backup source is a clean, low-THD inverter generator. 9) How long should I expect a Myers Predator Plus pump to last with proper maintenance? In my field experience, premium Myers deep well water pump installs see 8–15 years routinely, often longer in clean wells with correct sizing, minimal short-cycling, and good surge protection. I’ve inspected 20+ year Myers units still meeting curve after routine tank and switch maintenance. Lifespan killers: undersized pressure tanks (short-cycling), poor splices, lightning without SPDs, grit with cheap staging, and running at the edge of the curve. Keep starts under 10 per hour, test precharge annually, and verify running amps match the nameplate at your pressure setpoint. Do this, and 15 years is realistic. 10) What maintenance tasks extend well pump lifespan and how often should they be performed? Check pressure tank precharge yearly; set 2 PSI below cut-in (e.g., 38 PSI for 40/60). Inspect contacts in the pressure switch annually; replace if pitted. Exercise your generator quarterly under load; confirm pump starts smoothly. Test SPDs via indicator lights; replace if they’ve taken a hit. Pull and inspect at 8–10 years or earlier if amps rise or flow drops. Flush sediment filters regularly; grit shortens pump life. Do these simple things, and your Myers submersible well pump stays on curve longer, uses less power, and treats your backup gear kindly.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover? The industry-leading 3-year warranty exceeds the 12–18 months common with many brands. It covers manufacturing defects and performance issues under normal use, subject to installation meeting code and manufacturer guidelines. When paired with PSAM’s tech support, you get fast resolution and access to parts. In contrast, budget models often limit coverage to just a year and exclude key components. That extra two years matters; if anything crops up as your system cycles through seasons and outages, you’re covered. It’s insurance for your water supply during the period when most infant-mortality failures would appear. 12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands? Let’s run it. Assume a budget 1 HP pump at $450 with a 3–5 year life, plus two replacements in 10 years, emergency labor twice, and higher energy due to lower efficiency. You’re easily at $1,800–$2,400 in pumps, $800–$1,600 in labor, and $200–$400 extra in energy—$2,800–$4,400 total. A Myers Predator Plus at $900–$1,300, installed once, with 80%+ hydraulic efficiency and a 3-year warranty, plus better compatibility with a smaller, cleaner generator? Typically $1,800–$2,600 all-in over a decade. Add fewer emergencies and easier backup sizing, and the Myers solution wins on dollars and headaches. That’s why I call it the “buy once, cry once” pump. Conclusion: Your Water, On Your Terms—Even When the Grid Isn’t Backup power for Myers water well pumps comes down to honest numbers and quality parts. Size surge correctly, choose low-THD power, protect the circuit, and give the pump enough pressure tank drawdown to relax. When you marry those decisions to a Myers Predator Plus Series—with 300 series stainless steel, Teflon-impregnated staging, Pentek XE motors, field serviceable threaded assembly, and a 3-year warranty backed by Pentair—you get a well system that behaves under pressure and under outages. Carlos and Ana Peralta went from hauling buckets to taking hot showers during storms. Their 1 HP Myers starts clean on a 7.5 kW inverter generator, their 48V battery bank carries overnight, and their maintenance is a simple checklist. That’s the outcome I want for every rural homeowner, contractor, and emergency buyer. Need help sizing the backup for your Myers well pump? Call PSAM. I’ll run your pump curve, verify TDH, and spec the generator, inverter, transfer switch, and pressure tank so your system is worth every single penny the day the lights go out—and every day after.
