A cold shower that turns to a dribble, then nothing, has a way of convincing you that “monitoring” isn’t optional. When a deep well pump stalls, every faucet becomes a pressure gauge—and every minute without water reminds you that your well system is the backbone of your home. As PSAM’s technical advisor, I see this weekly: great families stuck with no water because no one tracked the simple performance markers that warn you months before a failure.
Meet the Tavares family—Luis (39), a high school ag-science teacher, and his spouse Brienna (37), a veterinary tech. They live on 6 acres outside Prosser, Washington with two kids, Mateo (9) and Elia (6), and a pair of stubborn goats that treat water buckets like negotiation tools. Their 320-foot basalt well had a 1 HP budget-brand submersible when they bought the place. After two summers of low pressure and sand spitting from the laundry tub, that pump finally died during a heat wave. A rushed replacement with a used Red Lion kept them afloat for a season, then cracked housings and a fried motor sent them back to square one.
When Luis called PSAM, we sized a Myers Predator Plus 1.5 HP, 12-stage, 10 GPM unit paired with a 44-gallon pressure tank and 230V single-phase power. Now water is stable—but here’s the truth: even the best pump—especially a Myers—performs longest when you monitor it right. Below, I’ll show you the exact performance checks I teach homeowners and contractors so your Myers deep well water pump hits that 8-15 year mark, with a realistic path to 20+.
We’ll cover: baseline flow/pressure benchmarking, amp draw profiling with the Pentek XE motor, pressure tank precharge and cycling control, pump curve comparisons, TDH and BEP targeting, grit and sand mitigation with Teflon-impregnated staging, seasonal drawdown checks, control box and pressure switch health, warranty documentation, energy monitoring, serviceable threaded assembly inspections, and practical alarm/backup strategies. If you rely on your well, this list can save you a lot more than cold showers.
#1. Establish Your Baseline – Flow, Pressure, and Electrical Profile Using a Predatory Plus Pump Curve
Reliable monitoring starts with a baseline. Without it, small degradations hide until your kitchen sink tells on you.

Baseline means documenting three things for your Myers submersible well pump: flow at a fixture, stable system pressure, and motor electrical draw. For a Predator Plus Series 10 GPM model at 1–1.5 HP, record flow at an outside spigot or laundry tub, log average operating pressure at the gauge, and measure motor amperage under steady demand. Reference the pump curve for your model against your TDH (total dynamic head) to confirm you’re running near BEP (best efficiency point)—that’s where Myers’ 80%+ hydraulic efficiency shows up in your power bill.
The Tavares family’s baseline: 9.6 GPM at the hose bib, 52 PSI cut-out, and 8.6 amps at 230V on their Pentek XE motor. That’s right on spec for their depth and elevation. We saved those numbers in a binder and phone notes.
How to Capture Flow and Pressure Correctly
- Install a Y-hose adapter with a simple GPM gauge at the hose bib nearest your pressure tank. Open one fixture at a time during the test. Record the flow for a full minute. Log pressures at cut-in and cut-out to the nearest PSI using your tank tee gauge. Normal residential settings are 40/60, but 30/50 and 50/70 are common. Record both points.
Motor Amps and Voltage—What “Healthy” Looks Like
- A properly loaded single-phase motor should draw near its nameplate amps under steady flow. Measure hot, after 5 minutes of run time. Abnormally high amps suggest blockage or excessive head; low amps may indicate partial dry-run or flow restriction. Track voltage drop under load. A sag more than 5% can point to wire gauge issues or tired breakers.
Baseline File—Your Lifespan Insurance
- Keep a single-page sheet: date, flow, pressures, amps, voltage, and noise/vibration notes. Compare quarterly. You’ll catch declines early, when fixes are cheap.
Key takeaway: Monitoring begins the day you install your Myers, not when the shower sputters. Baseline numbers are your warning lights—and the fastest way to protect your investment.
#2. Track Pressure Tank Health – Precharge, Cycling Rate, and Pressure Switch Coordination
Pressure tanks keep your submersible well pump from short-cycling to death. If you don’t measure precharge and cycle counts, you’re flying blind.
Your target is 30–90 seconds of run time per cycle under a typical draw, with the tank sized to absorb peak fixture usage. For a 44-gallon tank at 40/60 PSI, set precharge to 38 PSI (2 PSI below cut-in) with no water pressure on the system. A faulty precharge causes rapid cycling, pounding the motor’s thermal overload protection and shortening bearing life.
When Brienna noticed the laundry sink pulsing, we checked the tank: precharge at 29 PSI, cut-in/cut-out drifting to 37/57, and 18-second cycles at 1.5 GPM. A quick precharge correction and switch adjustment brought cycles back to 58 seconds.
Precharge—The Make-or-Break Number
- Turn off power, drain system to zero PSI, then set precharge with a digital tire gauge. Re-check seasonally; air migrates.
Pressure Switch—Small Device, Big Consequences
- A sticky switch or burned contacts causes late starts and overheats. Inspect contacts annually. Replace the switch if you see blackened points or erratic cut-in. Standard 40/60 is fine for most homes.
Cycle Counting—Your Wear Tracker
- Use a cheap tally counter or smart plug to estimate cycles/day. Big spikes point to leaks, running toilets, or tank issues. Your Myers pump loves long, fewer cycles.
Key takeaway: Most early pump failures trace to cycling abuse, not the pump itself. Keep the tank and switch in tune and your Myers runs cool and steady.
#3. Compare Real Performance to the Myers Pump Curve – TDH, Staging, and BEP Alignment
If you want to know whether your Myers deep well pump is happy, overlay your real TDH on the pump curve and check where your operating point sits.
TDH includes static lift (water level to ground), pressure converted to feet (PSI x 2.31), and friction loss through pipe, fittings, and components. For deep wells, static lift dominates. Use your well log or measure drawdown to get the working water level. Then plot your measured GPM and PSI against the curve. You want to ride the BEP hump, not the far left or right.
The Tavares system runs a 1.5 HP, 10 GPM Predator Plus. At 320’ depth with 60 PSI at the tank (138 feet of head), plus friction, their TDH lands around 420–440 ft under typical flow. Their operating point sits near BEP—explains the quiet motor and low amp draw.
Calculating TDH—Simple, Not Scary
- TDH = Static lift (ft) + Pressure head (PSI x 2.31) + Friction loss (estimate 5–20 ft for residential runs). Adjust for seasonal drawdown; deeper water in late summer adds lift.
Stages and Shut-Off Head—What It Means
- More stages increase head capability. Your Myers 10 GPM stacks efficiently, with shut-off head ratings up to 490 ft depending on model. Keep your normal operating point below 85% of shut-off to avoid heat and stress.
BEP Matters—Efficiency and Heat
- At or near BEP, you’ll see the best power factor and least heat. Straying far left (too much head) spikes amps; far right (too little head) risks cavitation.
Key takeaway: A 10-minute TDH check prevents a 10-hour pull. Your pump curve is a health chart—use it.
#4. Listen and Look—Noise, Vibration, and Water Quality as Early Warning Sensors
Your senses are underrated diagnostic tools for a Myers water pump. Unusual vibration at the tank tee, rhythmic pulsing at faucets, or metallic fines in aerators are early signs of trouble downstream.
A Predator Plus running true is nearly silent topside. If you’re hearing hammer or feel the drop pipe “kick” when the pump starts, check the check valve at the tank or the pump’s internal valve. In the Tavares home, a faint click-thud at shut-off turned out to be a snappy check valve at the tank tee. A high-quality inline check smoothed it out.
As for water quality, the intake screen and engineered composite impellers resist abrasion, but gritty water still scars plumbing. Sediment spikes are worth testing and filtering.
Vibration—Where It Shows Up
- Touch the copper or PEX near the tank tee. A smooth hum is fine; a rhythmic “bump” merits a check valve inspection and a torque arrestor review during the next pull.
Water Clarity—What’s Normal
- Brief cloudiness from aeration is normal. Persistent silt or orange tint suggests aquifer disturbance or iron bacteria. Install sediment filtration and sanitize the well if needed.
Air-in-Water Symptoms
- Spitting faucets or uneven pressure can indicate a drop in water level and intermittent entrainment. Log the timing; it often matches heavy irrigation periods.
Key takeaway: No tool beats a trained ear and a clean glass. Your pump tells on itself long before it fails.
#5. Amp Draw Trends—Pentek XE Motor Profiling and Thermal Protection Checks
What’s the most objective way to monitor a motor? Watch the amps. The Pentek XE motor on a Myers well pump is designed for high thrust with tight efficiency bands. When load changes, amps respond.
Create a simple log: ambient temperature, run duration, amp draw under a steady fixture flow, and any thermal trips. If amps creep up seasonally while flow stays constant, your head requirement likely increased (water level dropped), or a filter is clogging. If amps bounce, look for voltage issues or a degrading control box (for 3-wire models).
For Luis, summer irrigation downstream drops water levels and adds lift; his amps rise 0.6–0.8 A. That’s acceptable. We verified voltage stayed within 3% under full load.
Reading Nameplate vs Reality
- Compare measured amps to nameplate FLA. Expect to be within 5–10% under normal conditions. Above 110%? Investigate load or wiring.
Thermal Overload and Lightning Protection
- The motor’s built-in thermal overload protection should never be your routine savior. If it trips, something’s wrong: dry run, locked rotor, or severe voltage sag. The lightning protection helps, but add a quality surge protector at the panel.
When to Call It
- Rising amps + falling flow = pump wear or a partial blockage. Rising amps + steady flow = increased TDH. Falling amps + falling flow = supply/drawdown issue. Trend lines matter.
Key takeaway: If your amp curve stays flat, your pump lasts longer. It’s the closest thing to a crystal ball you’ll get.
#6. Grit Management—How Teflon-Impregnated Staging and Intake Screening Extend Service Life
Sand chews lesser pumps alive. Myers addresses it with Teflon-impregnated staging and self-lubricating impellers that shrug off fine grit. Even so, grit is a wear item; monitor and mitigate it.

Check faucet aerators monthly in new or disturbed wells. If you collect more than a teaspoon of fines in a month, consider a 60–100 micron spin-down filter upstream of the pressure tank and a finer cartridge downstream. Verify the intake screen integrity during service pulls and keep drop pipe straight with a quality torque arrestor.
The Tavares well sheds a bit of silt after big irrigation weeks. We added a spin-down and scheduled annual sediment checks. Their flow and amps stayed stable the following summer—good sign the impellers are unbothered.
Why the Staging Matters
- The engineered composite impellers and wear rings in Myers pumps resist abrasion scoring. Less drag equals lower amps and longer life. It’s the difference between running tight at year eight versus flopping around at year three.
Filter Placement—Don’t Starve the Pump
- Place sediment control after the tank unless you’re protecting a booster. Starving the suction side in a jet system is deadly; with submersibles, over-restricting outflow increases head and amps. Size filters to maintain adequate flow.
Monitor Post-Service Changes
- After well shocking or redevelopment, expect short-term debris. Log it. If it persists, consider a well screen evaluation.
Key takeaway: Myers built in grit resistance; your job is to keep the worst of it out of the lines.
#7. Seasonal Drawdown Audits—Measure Static and Pumping Water Levels to Protect Headroom
Water tables move. Your monitoring should, too. Twice a year—after spring rains and late summer—measure static level (pump off for 6–8 hours) and pumping level (pump running for 10+ minutes). This confirms your TDH assumptions and protects your pump from unplanned high head operation.
If your late-summer drawdown deepens by 20–40 feet, amps will rise and flow may dip. Plan irrigation schedules to avoid simultaneous household peak demand, or consider stepping up staging the next time you pull the pump.
For the Tavares well, static sits around 60 feet in May and 120–140 feet in August. Pumping level stabilizes near 220 feet under lawn watering. Well within the 1.5 HP model’s head room, but we watch it.
Simple Measurement Methods
- Use an electric water level meter or a chalked steel tape with a weight. De-energize, pull the well cap, and measure with care and clean technique. Log every reading.
Alarm Points—When to Act
- A year-over-year deepening trend of >40 feet may justify a re-evaluation of pump staging or household demand. Consider leak checks and irrigation changes first.
Pair with Energy Logs
- Rising kWh per gallon pumped often mirrors drawdown. Your energy bill becomes a drawdown proxy between measurements.
Key takeaway: Headroom isn’t academic. It’s your margin of safety when the aquifer takes a summer vacation.
#8. Pressure Switch, Control Box, and Wiring—The Small Parts That Make or Break Uptime
Monitoring isn’t just about the wet end. Electrical components steer your deep well pump and can create phantom “pump problems.”
Inspect the pressure switch quarterly: remove the cover, check for pitted contacts, verify clean spring action, and confirm the pressure setting with your gauge. For 3-wire well pump configurations, open the control box and visually inspect capacitor health (bulging or leaking is a fail). Use a non-contact thermometer to spot hot spots on lugs that indicate resistance.
The Tavares system runs a 2-wire configuration—simpler, fewer parts to fail, one reason I often recommend Myers 2-wire when specs allow. We still check lugs, breakers, and wire splices annually.
Wire Splice and Drop Cable
- The wire splice kit at the pump head must be factory-grade and watertight. A poor splice wicks water, shorts under load, and cooks motors. If you ever pull the pump, redo the splice with heat-shrink and adhesive-lined connectors.
Conductor Sizing
- Long runs need heavier gauge to limit voltage drop to <5% under load. Measure voltage at the panel and at the well head while running. Oversized wire is cheap insurance. </ul> Control Box Indicators (3-Wire)
- Hard starts, “chatter,” or delayed starts point to start capacitors and relays nearing end-of-life. Replace proactively at the 7–10 year mark.
- Light polishing and minimal endplay. No melted plastic, no chewed edges. Bearings should feel smooth. Anything gritty is your grit story written in plastic.
- Verify the internal check valve seals cleanly. Replace if you see seep-through or crack lines. Water hammer often traces to failing checks.
- After service, redo your baseline tests. A “reset” set of numbers validates the work and sets the clock for the next cycle.
- Invoice with model and HP, serial number, install date, photos of wiring and tank tee, baseline metrics, and every maintenance event. Digital and paper copies.
- Third-party certifications aren’t stickers. They reflect safety testing, material compliance (lead-free), and performance standards that stand up in real homes.
- Same-day shipping on in-stock pumps, tech help from pros who’ve actually pulled drop pipe at dusk, and access to the full Myers line through trusted Myers pump dealers and Myers pump distributors.
- For a 1–1.5 HP 230V submersible at 8–10 GPM near BEP, a steady home shouldn’t see more than a 5–8% seasonal swing in energy per gallon. Higher? Investigate.
- Dirty cartridge filters and half-closed valves add head. If energy per gallon rises after filter changes, re-check valve positions and consider pipe scale.
- Water lawns when household demand is low. Lower peak overlap reduces cycling and motor heat, saving kWh over time.
- Tee in a 4–20 mA pressure transmitter with a Wi-Fi bridge or use a smart pressure switch rated for pump duty. Test quarterly.
- Keep a 50–100 gallon potable storage in the garage. For bigger homesteads, a small booster pump from storage can ride through a parts delay.
- Keep your PSAM order history and a local installer’s number handy. Fast shipping is great; faster installs are better.
- Technical: Myers’ 300 series stainless steel wet end and threaded assembly allow on-site servicing—impeller stacks, wear rings, and checks—without scrapping the entire unit. The Pentek XE motor consistently holds a tight amp pattern near BEP, resulting in lower heat and extended bearing life. Franklin Electric builds a solid pump, but many models lean on proprietary control components and specialized dealer networks for parts. Application: For rural owners like Luis and Brienna, that difference determines whether a local contractor can complete a same-day repair after a pull, or whether you’re waiting days for a proprietary box. Monitoring is only as good as your ability to act on what you learn. Value: Over 10–15 years, fewer service delays, lower part costs, and on-site repairability make Myers, backed by Pentair and PSAM, worth every single penny.
- Technical: Goulds uses cast iron elements in several assemblies; in water with acidic pH or high mineral content, corrosion can creep into wear surfaces, raising amps and lowering flow. Myers’ all- 300 series stainless steel shell, discharge bowl, and shaft components, paired with engineered composite impellers, resist corrosion and abrasion. Monitoring amp stability tells the tale—stainless stays steady longer. Application: In the Yakima Valley where the Tavares family lives, mineral profiles change seasonally. Stainless holds spec in ways cast iron can’t. Performance monitoring confirms it: flat amp lines, consistent GPM, low maintenance. Value: With fewer corrosion-related service calls and an industry-leading 3-year warranty, Myers avoids the drip-drip of “little fixes.” For homeowners and contractors, that reliability is worth every single penny.
- Technical: Red Lion’s use of thermoplastic housings on many models cannot match the thermal and mechanical resilience of stainless steel under repeated pressure cycles. Myers’ stainless shell and self-lubricating impellers ride out hot/cold transitions and frequent starts without micro-cracking or impeller edge wear. On a monitor, you’ll see Red Lion age as rising amps and falling flow. Application: Pressure cycling from undersized tanks or irrigation overlap punishes plastics. With Myers, correct monitoring and a quick tank fix keep the wet end intact. With plastics, hairline cracks become sudden failures. Value: Fewer mid-life replacements, rock-solid staging, and better energy profiles make Myers’ Predator Plus Series worth every single penny.
