Introduction: Stop the Banging Before It Destroys Your System
Cold shower. Hot anger. A violent bang in the pipes that rattles the walls—followed by a dead-silent faucet. That’s the sound of water hammer taking a bite out of a well system. I’ve seen a single slam spike above 150 PSI at the manifold, split a copper tee like it was balsa wood, and send a submersible into early retirement. In rural homes that rely on private wells, you don’t have a city water crew on standby. You have your pump, your pressure tank, and the decisions you make today.
Two weeks ago, I took a call from Alex Carraway (38), a remote software engineer, and his wife Lila (36), a school nurse. The Carraways live on four acres outside Silverton, Oregon, with their kids Owen (8) and Maya (5). Their 185-foot private well ran a 3/4 HP pump that popped a relief valve twice in six months, scared the kids at every nighttime flush, and finally failed outright after a hard bang that rattled the basement. Their previous Goulds unit had an external check valve mounted at the tank; the clapper stuck, the column reversed, and the shock battered the line. When Alex found the motor cycling with almost no draw, it was a classic water hammer aftermath—air-lost tank, sticky check valve, pipe whip.
If that’s familiar, you’re in the right place. This list is your playbook to tame water hammer with the right hardware, tuned controls, and proven Myers Pumps engineering—especially the Predator Plus Series submersibles paired with intelligent plumbing components. We’ll cover stainless construction and Teflon-impregnated staging, the stabilizing role of a correctly sized pressure tank, the right check valve strategy, pressure switch cut-in/out tuning, constant pressure options, drop-pipe best practices, and the upgrades that keep your system quiet and healthy for years. We’ll show exactly how Alex and Lila solved their hammer problem with a Myers well pump and avoided another midnight plumbing disaster.
By the end, you’ll know how to size and configure a submersible well pump properly, choose between 2-wire and 3-wire configurations, read a pump curve, protect the system from shock waves, and leverage Pentair-backed reliability that’s worth installing once and enjoying for a decade or longer. Let’s get your lines silent and your home back to normal.
#1. Diagnose the Source of Water Hammer First – Column Reversal, Valve Slam, and Pressure Switch Timing
Water hammer isn’t magic—it’s physics. When flow stops suddenly, the moving water column slams to a halt and creates a pressure spike. In well systems, that’s often driven by sticky or poorly placed check valves, undersized or airlogged pressure tanks, and pressure switch settings that force short, abrupt pump cycles. With a Myers Pumps submersible—particularly the Predator Plus Series—you’ve got precise flow and head control on your side. But the connected controls and piping layout make or break hammer suppression.
- Alex and Lila Carraway’s hammer came from a stuck external check valve near the tank. The reversed column rebounded when the pump stopped, and the shock hammered the manifold. We fixed placement and settings, and the banging stopped that day.
Identify Your Hammer Pattern
A bang when a faucet closes points to fixture-level issues; a bang when the pump stops points to system-level timing. Listen near the pressure switch and tank at pump off—if you hear a thud, start with check valves and tank sizing.
Measure, Don’t Guess
Put a liquid-filled gauge at the tank tee and one at a hose bib 50+ feet away. If you see a spike of 20+ PSI at pump off, you have system hammer. A data point beats speculation—tune to it.
Key takeaway: Diagnose first, then spec the Myers well pump and components to match. Quiet systems begin with clear data.
#2. Upgrade to Stainless and Composite Durability – 300 Series Stainless Steel and Teflon-Impregnated Staging
Hammer doesn’t just make noise. It shreds marginal components. This is where the Myers Predator Plus Series shines: full 300 series stainless steel shell, discharge bowl, shaft, and wear ring, plus Teflon-impregnated staging with self-lubricating impellers that shrug off the micro-hammer events cheaper pumps don’t survive. Add the Pentek XE motor—a high-thrust, thermally protected design—and you’re buying the rugged core that tolerates real-world pressure spikes without deforming or seizing.
- In the Carraway well (185 ft, static 90 ft, dynamic 130 ft), we sized a 1 HP Myers Predator Plus at a 10 GPM curve to keep the TDH (total dynamic head) in the sweet spot. Quiet operation starts with the right staging and a motor that doesn’t hunt.
Why Material Choices Matter
Thin thermoplastics flex during surges; worn bearings let stages wobble and chatter. Stainless steel and engineered composites hold tolerances under load, which keeps pressure transitions smoother and extends life in systems that aren’t perfect.
Match the Curve to the House
A stable pump curve at your operating point (flow, elevation, friction losses) avoids rapid transitions when the switch opens. Myers’ 80%+ efficiency near BEP also trims electric bills while keeping the motor in a comfortable load band.
Key takeaway: Superior materials reduce the damage each hammer event can do. Start with a Myers water pump built to take a hit and keep running.
#3. Compare the Real-World Choices – Myers Predator Plus vs Franklin Electric and Red Lion (Detailed Analysis)
Material, motor, and serviceability determine how a system survives water hammer. The Myers Predator Plus Series uses 300 series stainless steel throughout the wet end with engineered composite impellers. Paired with the Pentek XE motor, you get tight axial tolerance, high thrust bearings, and thermal overload protection. Efficiency routinely clears 80% near BEP, easing motor heat. Franklin Electric submersibles are respected, but many configurations push proprietary control boxes and dealer-only parts streams. Red Lion relies on more thermoplastic in the wet end; under chronic hammer, I’ve seen housings spider-crack around the discharge.
On-site, this matters. When I tune a system, I want field-accessible parts and a threaded assembly that comes apart without special tooling. Myers gives exactly that. Installation is straightforward: match GPM rating, check the discharge size (often 1-1/4" NPT), and set the pressure switch. In hammer-prone lines, durable staging and bearings translate to fewer callbacks and stable pressures that don’t “hunt” on start/stop.
Bottom line: On stainless content, composite impeller durability, and motor thrust capacity, Myers beats budget plastics and sidesteps proprietary headaches. With PSAM stocking and same-day shipping, the lifetime value and uptime make Myers “worth every single penny.”
#4. Place and Select Check Valves Properly – Internal Check Valve Plus One at the Tank (Not Both Ends of the Line)
Bad check valve strategy is the number one source of preventable water hammer I fix in the field. A Myers submersible well pump includes an internal check valve to prevent backspin and backflow at the pump. What it doesn’t need is a second inline check halfway up the drop pipe. That split placement creates a trapped water slug that slams when the pump shuts off. The correct approach is simple: use the internal check at the pump and, if needed, add one high-quality spring-loaded check at the tank tee—never in between.
- For Alex and Lila, we removed the in-line mid-pipe check and installed a spring check at the manifold. The slam disappeared instantly, and pressure stabilized within one second of pump off.
Spec the Right Valve
Choose a stainless or brass spring-loaded check with a low cracking pressure. Swing checks are prone to chatter. A quiet close equals a quiet line.
Respect Vertical Columns
In deep wells, water columns store serious kinetic energy. Let the internal check stop backspin at the pump and the manifold check absorb minor reversals where piping is braced and supported.
Key takeaway: One check at the pump, one at the tank at most. Clean layout equals reduced hammer and longer Myers well pump life.
#5. Size the Pressure Tank and Tune the Switch – Larger Drawdown, Softer Stops
Nothing slams a line like a pump that short-cycles into a tiny tank. With Myers water well pumps, you get smooth hydraulics—so give the pump time to ramp and settle by installing a properly sized pressure tank and adjusting the pressure switch thoughtfully. A larger tank increases drawdown (usable gallons per cycle), which lengthens runtime and softens the transition when the switch opens.
- The Carraways had a 20-gallon tank delivering only 6 gallons drawdown at 40/60. We upgraded to an 80-gallon tank with ~24 gallons drawdown. Result: the submersible well pump ran longer, stopped less often, and the whole system quieted down.
Setpoints That Work
Common residential: 40/60 PSI with the tank precharge at 38 PSI (2 PSI below cut-in). For multistory homes, 50/70 can help; just confirm your pump curve supports the higher head without leaving BEP.
Run Time Target
Aim for 60–120 seconds per cycle under steady draw. Longer is often better for motor cooling and line stability. If your run time is 15 seconds, you’re begging for hammer.
Key takeaway: Bigger tanks and smart switch tuning protect lines and make a Predator Plus Series install whisper-quiet.
#6. Stabilize Piping from the Wellhead to the Manifold – Drop Pipe, Pitless, and Support Spacing
Water hammer intensifies in poorly supported piping. The drop pipe inside the casing, the pitless adapter, and the horizontal line into the basement must be stable and aligned. Choose schedule-rated drop pipe, use a torque arrestor above the pump if your well is known for startup twist, and mount the manifold with steel brackets. Soft transitions fight shock.
- Alex’s manifold was hanging off a single strap. We replaced it with a rigid bracket, added cushioning at contact points, and spaced supports every 4–5 feet. The system stopped “walking” at pump off.
Drop Pipe Choices
For 185 feet, SDR-rated poly with proper insert fittings and double stainless clamps works; for hammer-prone or deeper wells, consider sch 80 PVC or galvanized with dielectric isolation. Keep joints square and tight.
Wellhead Assembly
Secure the well cap, use a proper pitless adapter, and align the discharge to avoid side-load on the manifold. Add a torque arrestor and cable guards to keep the motor leads from slapping the pipe.
Key takeaway: Solid mechanical support is cheap insurance for any Myers water pump install. Don’t let your system flex and amplify the shock you’re trying to eliminate.
#7. Pentek XE Motor Control and Wire Choices – 2-Wire Simplicity vs 3-Wire Control and What It Means for Hammer
The Pentek XE motor paired with a Myers wet end is built for clean starts and controlled thrust. Start strategy matters for hammer: a hard, snappy start into a minimal tank is a recipe for “thunk.” A 2-wire well pump integrates start components in the motor—simplifying installation and reducing points of failure. A 3-wire well pump uses an external control box, which can be advantageous for serviceability and certain start profiles.
- For the Carraways, I specified a 230V 1 HP 2-wire setup to avoid extra components and wiring. The XE’s high-thrust bearings and lightning protection add resilience without added complexity.
When 2-Wire Wins
Shallower or mid-depth wells (up to ~300 feet TDH), straightforward wiring, and fewer accessories. It’s often quieter on start and costs $200–$400 less than a 3-wire plus control box.
When 3-Wire Helps
Very deep wells or specialized control needs can favor 3-wire for diagnostic ease and swap-friendly components. Still quiet when combined with a big tank and tuned switch.
Key takeaway: Select the configuration that simplifies your system without sacrificing control. With Myers Pumps, both paths are robust, efficient, and hammer-friendly when installed right.
#8. Myers vs Goulds (and Why Stainless Wins on Hammer) – Detailed Comparison for Corrosive and Shock-Prone Systems
Goulds builds capable pumps, but many models rely on cast iron components in the discharge or staging that don’t love acidic or high-mineral water—especially when hammer cycles flex tolerances at each stop. Myers Predator Plus Series leans into 300 series stainless steel throughout the wet end and engineered composite impellers that resist micro-chipping from sand and grit. When you combine that with a tight pump curve match and a high-thrust Pentek XE motor, you get a machine that survives thousands of starts and countless micro-shocks without developing slop or chatter.
For homeowners like the Carraways—who live with slightly acidic Oregon water (and some seasonal fine grit)—the all-stainless approach removes a whole category of failure. Stainless is both corrosion resistant and structurally consistent under spike pressure. Service-wise, the threaded assembly on Myers is field-friendly, and PSAM can ship same-day if you ever need parts.
In short: corrosive water and occasional hammer? Myers stainless plus composite staging holds up better than cast iron in the long run, and the quiet operation you gain at home is worth every single penny.
#9. Constant Pressure Options and Flow-Control Tricks – Taming Hammer with Softer Ramps and Smoother Stops
Hammer lives in sharp transitions. Constant pressure solutions smooth the whole show. Pair a Predator Plus Series with a properly sized booster or a variable-speed control to hold a set pressure (say 60 PSI) during varying demand. Even without a full VFD, a smart flow-control valve or a soft-close fixture valve can shave the spike.
- The Carraways wanted simplicity, so we stuck to a big tank and tuned switch. For clients with irrigation zones or long plumbing runs, I recommend constant pressure to keep startup and stop events predictable and soft.
Choose Your Tools
- Constant pressure kits: stable setpoint, fewer on/off cycles. Flow-control valve at the manifold: limits maximum flow ramp rate. Soft-close fixture valves: stop the local slam at the source.
Balance Complexity and Payoff
Not every home needs a VFD. If your pressure pattern is tame, a quality tank and an internal check valve plus one spring check outperform extra electronics for less money.
Key takeaway: Smooth transitions cut hammer. Whether you choose constant pressure or just better hardware, Myers pumps respond beautifully to a well-tuned system.
#10. Install and Protect for the Long Haul – PSAM Kits, Warranty, and Quick-Ship Support
You don’t have time for repeat failures. Myers Pumps offer an industry-leading 3-year warranty, Made in USA quality, and NSF/UL/CSA certifications. With PSAM stocking drop pipe, tank tee kits, wire splice kits, pitless components, and pressure tanks, we ship complete solutions fast—often same day. That means fewer trips, fewer surprises, and less downtime.

- For Alex and Lila, we shipped a complete kit: 1 HP Predator Plus, 80-gallon tank, stainless spring check, manifold kit, and supports. Start to finish, water was back on in 24 hours—and it’s been silent ever since.
Rick’s Picks for Hammer-Prone Installs
- Predator Plus 10 GPM at the right head 80–120 gallon pressure tank for most 3–4 bath homes Spring check at tank tee Rigid manifold bracket and spaced supports Precharged tank 2 PSI below cut-in
Key takeaway: Put proven parts behind a proven pump. With Pentair backing, PSAM logistics, and my field support, your investment will be quiet, efficient, and long-lived.
FAQ: Water Hammer and Myers Water Well Pumps
How do I determine the correct horsepower for my well depth and household water demand?
Start with your system’s TDH (total dynamic head) and required flow. TDH combines vertical lift (water level to highest fixture), friction losses in pipe/fittings, and desired pressure at the house. A typical 3–4 bed home needs 8–12 GPM at 40–60 PSI. If your dynamic water level is 130 feet and you want 50 PSI at the house, your TDH may land around 200–230 feet once you include friction. Cross that with the pump curve for a 1 HP or 1.5 HP Predator Plus Series to find the best fit near BEP. Example: For the Carraways’ 185-foot well and 10 GPM demand, a 1 HP 10 GPM Myers model hit 60 PSI comfortably with headroom. My rule: size for your peak usage (two showers + laundry) without running the motor at the end of its curve. PSAM can run the numbers for you if you provide depth, static/dynamic levels, and pipe size.
What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
Most households function well at 8–12 GPM. Larger homes with irrigation zones can need 15+ GPM. Pressure is created by stacked stages in a multi-stage pump; each stage adds head. A 10 GPM submersible well pump with 10–15 stages can create 250–490 feet of head depending on model. That translates to 110–210 PSI at shutoff—plenty to maintain 50–70 PSI at the house after losses. The trick is matching stage count to your TDH so the pump runs near its efficient window. Myers Predator Plus Series pairs engineered composite impellers with tight tolerances for consistent head per stage, which stabilizes pressure and reduces the “surge and dip” feeling that can trigger hammer.
How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
Efficient hydraulics come from impeller geometry, smooth passageways, and tight mechanical tolerances. Myers uses Teflon-impregnated staging and precision-molded impellers to reduce leakage and turbulence, while the Pentek XE motor converts more electrical power into usable shaft work. At or near BEP, many Predator Plus models exceed 80% hydraulic efficiency, trimming electric bills by up to 20% over less efficient setups. That efficiency matters for hammer too: a motor running cool and steady is less prone to abrupt behavior at start/stop. Compared to thermoplastic-heavy pumps that flex under load or units with looser stage tolerances, Myers holds its line—literally and figuratively.
Why is 300 series stainless steel superior to cast iron for submersible well pumps?
300 series stainless steel resists corrosion in mineral-rich or slightly acidic water and keeps its shape under pressure spikes. Cast iron can pit, rust, and grow rough internally, which increases friction and disrupts laminar flow. Under repeated water hammer, cast iron interfaces can loosen or even fracture at thin sections. Stainless components—shell, discharge bowl, wear ring—maintain alignment so the impellers spin true. That translates to stable pressure and longer bearing life. In the field, I’ve pulled stainless Myers pumps after a decade of service that looked ready for another five. In the same wells, mixed-metal or cast-heavy pumps showed scale, pits, and worn fits after half that time.
How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
Fine grit works like liquid sandpaper. Teflon-impregnated staging creates a low-friction interface that sheds abrasive fines rather than embedding them. Self-lubricating impellers ride on a thin film that limits direct wear and keeps the impeller edges crisp, maintaining head per stage across years of service. Pair that with a screened intake and correct pump elevation (at least 10–15 feet above the well bottom), and you’ve set up your pump to survive seasonal sediment without the “grind and squeal” that destroys cheap gear. In Oregon and across the Midwest, I’ve seen Myers units outlast budget pumps by 2–3x in sandy aquifers.
What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
The Pentek XE motor is a single-phase, high-thrust design engineered for submersible duty. It employs optimized windings for low amperage draw, robust thrust bearings for multi-stage axial loads, and thermal overload protection with lightning protection baked in. That means cleaner starts, less heat, and fewer nuisance trips. Efficiency shows up as cooler operation and longer insulation life. In practice, XE motors start decisively and settle fast—no drama at the pressure switch, which reduces hammer risk. For 230V installs at 1 HP and 1.5 HP, the XE combines power and poise in a way that’s immediately noticeable at the tap.
Can I install a Myers submersible pump myself or do I need a licensed contractor?
A skilled DIYer can install a Myers submersible well pump, but only if you’re comfortable with electrical work, hoisting 100–300 feet of drop pipe, and sealing pitless connections. You’ll need a proper wire splice kit, torque arrestor (if recommended), and safe handling for a 230V AC electric pump. The stakes are high; a dropped pump or Additional hints bad splice is an expensive mistake. I advise homeowners to handle the trenching and manifold prep and hire a pro for the pull and set. PSAM can bundle everything—pump, pitless, pressure tank, tank tee, fittings—and ship it same day so your contractor can get you back online fast.
What’s the difference between 2-wire and 3-wire well pump configurations?
A 2-wire well pump contains the start components inside the motor—no external control box required. It’s simpler, cheaper up front, and perfect for many residential depths and flows. A 3-wire well pump uses an external box for start capacitors and relays. Advantages include easier above-ground troubleshooting and component replacement. Performance-wise, both run beautifully when matched to head and flow. For the Carraways, a 1 HP 2-wire reduced parts count and cost, and the Pentek XE motor handled starts smoothly. For deeper wells or advanced controls, 3-wire is a smart option. PSAM will steer you to the right choice based on depth, amps, and service preferences.
How long should I expect a Myers Predator Plus pump to last with proper maintenance?
With correct sizing, myers water pump clean power, and a stable plumbing layout, Myers Predator Plus Series pumps typically run 8–15 years, with many systems crossing the 20-year mark. Maintenance is simple: keep the pressure tank charged, inspect the manifold annually, test pressure switch function, and verify the relief valve isn’t weeping. In hammer-prone areas, ensure supports stay tight and the spring check valve at the tank closes quietly. The 3-year warranty offers early-life assurance; the stainless/composite construction pays dividends in years 6–15. I’ve retired Myers units not because they failed, but because homeowners upsized during remodels.
What maintenance tasks extend well pump lifespan and how often should they be performed?
- Annually: Verify tank precharge (2 PSI below cut-in), check switch contacts, inspect for leaks, confirm gauge accuracy. Every 2–3 years: Pull and inspect the manifold check valve; replace if it chatters or sticks. After any lightning event: Confirm amperage draw and insulation health; XE motors have lightning protection, but verify. Ongoing: Keep the well cap sealed, protect wires with guards, and ensure the pitless adapter is tight.
Do this, and your Myers well pump runs cool, cycles smoothly, and avoids the cumulative abuse of hammer.
How does Myers’ 3-year warranty compare to competitors and what does it cover?
The 3-year warranty from Myers outpaces many competitors who stop at 12–18 months. Coverage addresses manufacturing defects and performance issues. In my experience, the combination of Pentair backing and PSAM support means fast answers and practical solutions. Compare that to brands with shorter warranties or dealer-only service paths and you’ll appreciate the ownership experience. When hammer is involved, warranty often reveals build quality—stainless stages, strong bearings, and composite impellers simply fail less. That’s why warranty length matters; it reflects confidence in real-world conditions.
What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Budget pumps can look attractive up front, but factor two replacements in a decade, higher kilowatt-hours due to lower efficiency, and emergency labor—and the math flips. A Predator Plus Series with 80%+ efficiency near BEP, a durable wet end, and a robust XE motor typically saves 15–30% in energy and 1–2 full pump swaps over 10 years. Add avoided drywall repairs from hammer-induced leaks and the numbers get clearer. PSAM’s competitive pricing and fast shipping already keep initial costs fair; reliability and silence are the dividends you notice every morning.
Comparison Spotlight: Myers vs Franklin Electric and Goulds Pumps (Serviceability and System Harmony)
Franklin Electric makes strong motors, no doubt. But in many layouts, their submersibles steer you into specific control boxes and proprietary parts trails. Goulds, while reputable, still integrates cast iron components across lines that don’t love mildly acidic or iron-heavy water, particularly when water hammer cycles flex tolerances. Myers Predator Plus answers with full 300 series stainless steel, engineered composite impellers, and broad availability of standard parts through PSAM—plus the Pentek XE motor with high thrust capability and thermal overload protection. Efficient hydraulics (80%+ near BEP) keep the motor cool and your power bills lower.
In living systems, field serviceability is everything. When I rebuild or tune, I want a threaded assembly I can open without hunting for dealer-only tools. I also want pumps that play well with bigger pressure tanks, spring checks, and tuned pressure switches—the hardware trio that silences hammer. Myers does. Franklin and Goulds can, but often at higher long-term service cost or complexity that isn’t necessary for most homes.
For rural families who can’t lose water for a week, the smooth integration, fast parts access, and corrosion resistance of Myers deliver measurable peace of mind—worth every single penny.
Conclusion: Quiet Lines, Reliable Water, One Smart Myers Decision
Water hammer is a symptom of system timing, component choices, and support details—not an inevitable headache. When you pair a Myers Pumps Predator Plus Series submersible well pump with stainless strength, Teflon-impregnated staging, a right-sized pressure tank, smart check valve placement, and tuned pressure switch setpoints, the slam goes silent. For Alex and Lila Carraway in Oregon, that meant moving from six months of pipe-banging chaos to a whisper-quiet, steady 60 PSI. The Pentek XE motor starts clean, runs cool, and stops without a thump. PSAM bundled the parts, shipped same day, and kept their home running.
