A cold shower that cuts to a trickle, faucets sputtering like a bad camp stove, the pump whirring longer every day—air leaks in a shallow well system announce themselves loudly. Let them go, and you’ll burn out seals, overheat motors, and shorten pump life by years. Ignore a jet pump ingesting air, and it will cavitate and lose prime, forcing repeated priming and eventually scoring the impeller and diffuser.
Two Saturdays ago, I got a call from a rural family near Geneva, Ohio. Meet the Cebriáns. Luis Cebrián (38), a high school math teacher, and his wife, Marta (36), a home-based bakery owner, live on seven acres with their kids—Sofía (8) and Nico (5). Their 38-foot shallow well had been running a 1/2 HP jet pump from a budget brand for three frustrating years. After the third priming session in one week and a midnight sputter that shut off the dishwasher, Luis discovered his system wasn’t just losing prime—it was pulling air somewhere between the well cap, the foot valve, and the suction fittings. A cracked thermoplastic housing on his old pump didn’t help.
We installed a Myers shallow well system the following Monday, sized correctly, with upgraded suction plumbing and a systematic leak check. Their system has run silent since. This checklist is the process I used to find and eliminate air leaks—precisely the kind of method that keeps a properly installed Myers shallow well pump delivering steady pressure for a decade or more.
Here’s what we’ll cover:
- #1 pinpoints air leaks by symptom mapping and pressure behavior. #2 focuses on prime retention and foot valve diagnostics. #3 zeroes in on suction-side fittings and vacuum testing. #4 addresses well seals and cap gaskets as hidden culprits. #5 explores pressure tank/pressure switch misreads that mimic air leaks. #6 shows the soapy water and smoke trick—properly executed. #7 explains vacuum gauges and clear section tubing for visual diagnostics. #8 details how Myers jet pump tolerances help you isolate problems faster. #9 compares Myers vs Goulds and Red Lion in corrosion resistance and casing integrity. #10 lays out repair-grade sealing and piping upgrades that outperform quick fixes. #11 walks you through post-repair validation and BEP-friendly operating checks.
Along the way, I’ll give you exact parts, specs, and pro tips. As PSAM’s well pump specialist, I’ll also explain why Myers jet pumps—designed with the same engineering DNA found in the Predator Plus Series—save money over the long haul, and how PSAM gets you what you need fast with same-day shipping on in-stock pumps, fittings, tank tees, and sealants.
Let’s keep your well water steady, quiet, and clean.
#1. Start With Symptom Mapping – Pressure Switch, Gauge, And Suction Line Behavior Under Load
A quick scan of system behavior tells you where air is getting in and how bad it is. Air leaks don’t hide for long under a pressure switch cycle.
- A pump that hits 30 PSI slowly but never climbs to a 50 PSI cut-out? That’s classic suction-side air entrainment causing cavitation. Frequent cycling every 20–60 seconds with no obvious water use points to trapped air in the pressure tank or a leak on the suction side. A gauge needle that twitches or drops rapidly when the pump stops suggests a failing check valve or foot valve letting the suction line drain back, pulling air.
Luis noticed his pressure switch repeatedly clicked at 32–34 PSI and never reached his 50 PSI cut-out. That gave away a suction-side air breach. We confirmed with a shutoff at the tank tee and a vacuum test.
Visual Clues That Narrow the Hunt
- Sputtering at faucets plus milky or cloudy water = air ingestion. Pump runs hot and noisy with a gravelly sound = cavitation at the jet assembly. Pressure gauge jumping during flow = air passing the gauge port.
What to Log Before You Touch Wrenches
- Current cut-in/cut-out settings (commonly 30/50). Static pressure drift over 15 minutes with pump off. Time to reach cut-out (if it ever does). Any visible drips on the suction line.
Key Takeaway
Start with behavior, not guesses. A $10 notebook and 15 minutes of logging can cut diagnosis time in half.
#2. Prime Retention Test – Foot Valve, Drop Pipe, And Check Valve Integrity
When a shallow well system won’t hold prime overnight, air is entering from the water source or seeping backward through a faulty foot valve or check valve. In a 38-foot shallow well like the Cebriáns’, a stuck-open foot valve drained the suction line and introduced air into the jet assembly. Result: first run every morning sounded like a blender.
The Overnight Static Test
- Kill power to the pump. Prime the pump fully and verify the casing is full. Close a service valve at the tank tee so the house side is isolated. Note pressure. Wait 8–12 hours. If pressure drops and the pump housing empties, your foot valve or line is bleeding off.
Confirm With a Temporary Cap
If possible, cap the suction port at the pump and pressure test to 15–20 PSI. If it holds, the leak is down-hole: foot valve, drop pipe, or well seal. If it doesn’t, the leak is at the pump casing or immediate fittings.
When To Replace Parts
- Foot valves older than 5–7 years in iron-rich water are suspect. PVC drop pipe with sun-checked threads or stress cracks needs swapping. Upgrade to a brass or stainless steel foot valve where possible for longevity.
Key Takeaway
A prime that won’t hold almost always means a suction-side leak. Start at the bottom: foot valve first, then come up the line.
#3. Suction Fittings And Vacuum Test – NPT Threads, Sealants, And Micro-Leaks Under Suction
Most “mystery” air leaks happen within three feet of the pump on the suction side. That’s where a lot of DIY installs lose the plot: misapplied pipe dope, Teflon tape stacked wrong, or mixed materials with mismatched thermal expansion. Myers jet pumps are forgiving, but no pump wins against a sloppy suction joint.
Vacuum Gauge Method
- Install a vacuum gauge on a tee between the pump’s suction port and the first fitting. Run the pump with an outlet valve partially closed to create strong suction. A stable vacuum with normal draw is good. A dropping or fluctuating vacuum indicates a small leak bleeding air in.
Threaded Joint Best Practices
- Use Schedule 80 PVC or brass on the suction side; avoid thin-wall fittings. Apply two wraps of PTFE tape followed by a non-hardening anaerobic thread sealant on male threads only. Keep joints aligned—no cross-threading, no unions under stress. Support the suction line—no cantilevered weight hanging off the pump housing.
Luis had a hairline crack on a PVC elbow right at the pump. Under suction, it pulled air; under pressure, no water showed. The vacuum gauge told the truth in five minutes.
Key Takeaway
Air leaks act different than water leaks. A vacuum test beats a flashlight every time.
#4. Well Cap, Well Seal, And Conduit – The Overlooked Entry Points For Air And Contaminants
Aging well seals and caps cause endless misdiagnoses. When the seal dries out or the conduit isn’t properly sealed, air—and worse, insects and surface contaminants—can enter the casing and travel to your suction point.
Inspect The Wellhead
https://www.plumbingsupplyandmore.com/1-2-hp-submersible-well-pump-9-stage-design.html- Look for a cracked cap, missing gasket, or non-UV-rated electrical conduit. Ensure the well seal compression rings are tight and the rubber isn’t brittle. Verify wire entries use watertight cord grips; no duct tape “solutions.”
Sanitary Concerns
Beyond air, a compromised well cap risks bacteria and debris. If you’re seeing sudden air plus odd tastes or sediment, address the wellhead immediately and consider a shock chlorination after sealing.
Luis And Marta’s Fix
Their conduit elbow had an open gap where it meets the cap. We replaced the cap, installed a proper seal with cord grips, and secured conduit with an exterior-rated fitting. Air and ants—problem solved.
Key Takeaway
Seal the top of the system as carefully as the bottom. A sanitary well cap is non-negotiable.
#5. Pressure Tank And Pressure Switch Checks – Don’t Confuse Short-Cycling With Air Leaks
Air leaks and pressure tank issues look similar at the faucet. But a failed bladder or wrong precharge in the pressure tank causes rapid cycling that mimics suction leaks. Diagnose the tank correctly before tearing apart the suction line.
Bladder and Precharge Test
- Kill power and drain the system to zero PSI. Measure air precharge at the Schrader valve. It must be 2 PSI below cut-in (e.g., 28 PSI for a 30/50 system). If water comes out the Schrader valve, the bladder is ruptured—replace the tank.
Pressure Switch Reality Check
- Dirty or pitted contacts cause delayed cut-in/cut-out. Clean or replace. Verify the pressure gauge is accurate. A $12 liquid-filled gauge from PSAM eliminates guesswork.
Why It Matters
A short-cycling pump runs hotter, invites cavitation, and exaggerates any small air leak. Fix the tank and switch, then reassess. For the Cebriáns, a proper 28 PSI precharge steadied the cycle and made the air leak diagnosis obvious.
Key Takeaway
Stabilize tank and switch first. Stable cycling makes air leaks stand out.
#6. Soapy Water And Smoke Test – Old-School, But Do It The Right Way
Nothing beats a soapy water test on accessible suction fittings—if you actually create suction while you test. A static test won’t reveal a micro-leak that only appears under vacuum.
How To Run It
- Mix dish soap with water in a spray bottle. Generous suds are your friend. With the pump running and a downstream valve partially closed, spray every suction joint from the well line to the pump volute. Watch for inward “sipping” of suds or subtle bubble movement. On vacuum, you’ll see bubbles pulled in rather than blown out.
Smoke Amplifier Trick
If you can safely introduce non-toxic smoke near joints (think incense stick), airflow will reveal the leak direction. Move slowly; tiny leaks need patience.
Luis spotted a faint ripple at a union thread using suds while I held the valve half-closed. We re-sealed with anaerobic sealant and corrected the misaligned union.
Key Takeaway
Create suction while testing. No vacuum, no proof.
#7. Clear Suction Window And Temporary Check Valve – Visual Confirmation Of Entrained Air
When diagnosis drags, I install a short section of clear PVC on the suction run as a temporary viewing window. See bubbles? You’ve confirmed entrainment. Combine this with a test check valve placement to isolate sections.
Two-Part Isolation
- Install a temporary check valve close to the pump inlet. If bubbles stop, the leak is upstream (toward the well). If not, the leak is at the pump or immediate fittings.
Flow Rate Control
Throttle a downstream valve to 1–2 GPM. Lower flow increases vacuum on the suction line and makes bubbles easier to detect. Don’t run throttled for long—this is diagnostic only.
The Cebrián Snapshot
We saw a steady stream of pinhead-sized bubbles during partial flow. After re-sealing a suspect elbow and replacing a fatigued union, the line ran clear under every test condition.
Key Takeaway
Don’t guess—watch. Visual confirmation stops the parts cannon approach.
#8. Why Myers Jet Pumps Make Leak-Finding Easier – Tight Housings, Real Gaskets, And Serviceable Design
A quality Myers shallow well pump gives you better diagnostic signals because the pump itself isn’t the source of “phantom” air. The machining on the volute and jet assembly, combined with proper gasket materials and a robust threaded assembly, means you can trust the housing. That focuses troubleshooting where it belongs: the suction side plumbing and the well.
Engineering That Matters
- Precision-mated jet and diffuser surfaces resist self-entrainment. Correct gasket compression eliminates “breathing” at the casing seam. Rigid cast components minimize distortion when threaded piping is over-tightened.
Field Serviceable
Myers’ serviceable design lets any qualified contractor replace gaskets, inspect the ejector, and reseal the casing without proprietary tools. You won’t be stuck waiting on a dealer network to check a simple leak path.
When I installed the new Myers 1/2 HP jet for Luis and Marta, I knew if we still saw air, the problem wasn’t in the housing. That confidence speeds up diagnosis and saves callbacks.
Key Takeaway
A tight, well-built pump narrows your search. Myers delivers that out of the box.
#9. Comparison Deep-Dive: Myers vs Goulds And Red Lion – Materials, Integrity, And Real-World Leak Resistance
Materials tell the story. In shallow well systems, suction leaks often masquerade as pump defects—especially with pumps that flex, distort, or corrode.
Technical performance: Myers uses 300 series stainless steel components in critical areas across its lineup and engineered housings that hold shape under suction stress. Precise gaskets and true flat mating surfaces keep the casing airtight. Red Lion, with common thermoplastic housings in many models, is more prone to hairline cracking and thread distortion under thermal cycling, which invites air. Goulds offers durable units, but cast iron sections can corrode in acidic or high-mineral water, compromising seal integrity over time. With Myers’ fit and finish, the pump housing stays out of the failure tree, and your leak hunt focuses where it should: fittings and well hardware.
Real-world differences: In the field, I see Red Lion housings fine on day one, then taking on micro-fractures that show up only under suction—baffling homeowners chasing invisible plumbingsupplyandmore.com leaks. Goulds lasts longer but picks up corrosion in borderline pH wells, making future gasket seals unreliable. Myers, backed by Pentair engineering, holds tight in varied water quality, and its field serviceable design means gaskets and ejector components can be reset with predictable results by any contractor.
Value verdict: For rural homes that can’t risk downtime, Myers’ materials, sealing surfaces, and serviceability reduce diagnostics, protect the motor, and extend life—worth every single penny.
#10. Sealant, Pipe, And Fitting Upgrades – The Fix That Ends The Leak Hunt For Good
Once you locate the air leak, fix it like a pro. Do it halfway, and you’ll be back to priming in a month. Myers pumps reward good piping practice with quiet, steady operation and peak efficiency at the best efficiency point (BEP).
Materials That Hold Vacuum
- Use Schedule 80 PVC or Type L copper on suction runs; no DWV fittings. Prefer full-brass unions and valves on the suction side. Keep the suction run as short and straight as possible—fewer elbows, fewer failure points.
Sealants That Don’t Quit
- Wrap male threads with two tight turns of PTFE tape. Follow with a high-quality non-hardening anaerobic thread sealant rated for potable water. Let it cure per spec before pressurizing.
Mechanical Support
- Add a proper mounting bracket to relieve weight from the pump volute. Strap vertical sections every 4 feet. Use a true well seal with compression rings—no improvising.
Luis and I re-piped his suction line in a clean sweep: Schedule 80 from the well seal to the pump, one long sweep elbow, brass union at the pump. It’s been whisper-quiet and airtight since.
Key Takeaway
Upgrade materials once, and you won’t be chasing bubbles again.
#11. Post-Repair Validation – Vacuum, Pressure, And BEP-Centered Performance Checks
After repairs, validate with the same rigor you used to diagnose. A Myers jet pump should pull quickly, build to cut-out within a reasonable time, and cycle calmly with no needle jitter.
Three-Point Confirmation
- Vacuum stability: Watch the vacuum gauge hold steady during a 2–3 GPM draw. Pressure rise: Time the climb from cut-in (30 PSI) to cut-out (50 PSI). Smooth and fast is the goal. Flow proof: Open a high-demand fixture and verify steady flow without sputter or milky water.
BEP And Efficiency
Match your pump’s curve to your system’s TDH and flow demand. Keep the operating point near BEP for quiet performance and motor longevity. Myers curves are straightforward, and we stock them at PSAM for quick reference.
Luis’ system now hits 50 PSI in under 30 seconds from 30 PSI, holds prime for days, and runs at a stable draw with zero vacuum fluctuation. That’s an airtight win.
Key Takeaway
Trust data, not hunches. If the numbers are right, the water will be, too.
Comparison Deep-Dive: Myers vs Franklin Electric – Control Simplicity And Serviceability That Speed Up Air-Leak Diagnostics
Technical performance: Franklin Electric builds capable pumps, but many setups lean on proprietary control boxes and tuning that complicate field work. Myers offers both 2-wire and 3-wire well pump options across product lines and keeps controls simple and accessible. For shallow well jet systems, Myers’ straightforward, field serviceable assembly and standard single-phase controls make diagnostics and air-leak detection faster. Less time deciphering controls means more time isolating the suction breach. Efficiency-wise, Myers’ jet designs and Pentair influence support strong operating efficiencies when the system is sized to the pump curve and cut-in/cut-out settings.
Real-world application: In service calls, I’ve lost hours waiting on specific control box components in Franklin setups, which pushes homeowners into extended downtime. With Myers, standard components, clear manuals, and ready parts from PSAM let me stabilize the system and run a full suction integrity test the same day. Faster restoration, fewer parts dependencies, and consistent sealing surfaces reduce callback risk.
Value proposition: For rural families who can’t wait, Myers’ open, contractor-friendly design shortens diagnosis and restores water faster, backed by PSAM’s same-day shipping when time matters most—worth every single penny.
Comparison Deep-Dive: Myers vs Goulds – Corrosion Resistance And Long-Haul Reliability In Shallow Well Environments
Technical performance: Goulds makes durable jet pumps, but models with cast iron components face corrosion risk in low pH or high-mineral water. Corroded mating surfaces can undermine gasket seals, introducing micro air leaks over time. Myers’ use of 300 series stainless steel in critical components across the brand’s lineup, plus precision casting and high-quality gasket materials, maintains housing integrity longer. Myers’ attention to sealing surfaces and threaded assembly quality holds vacuum reliably—a decisive advantage when every bubble matters.
Real-world application: In Northeastern systems like the Cebriáns’, water chemistry varies by season. I’ve revisited Goulds installs where a once-tight seam took in air after surface corrosion set in. By contrast, Myers units maintain consistent sealing and deliver stable priming behavior longer. For homeowners, that means fewer early-morning prime losses and fewer emergency calls.
Value proposition: Over a 10-year span, avoiding corroded seals and recurring air leaks saves repair costs and protects motor life. With Pentair’s backing and PSAM’s parts pipeline, Myers keeps systems airtight and dependable—worth every single penny.
FAQ: Expert Answers To Keep Your Myers System Airtight And Efficient
1) How do I determine the correct horsepower for my well depth and household water demand? Start with your depth-to-water, horizontal run, and required flow. For a shallow well (25–50 feet), a 1/2 HP Myers jet pump typically supports a small home at 6–8 GPM with a 30/50 pressure switch. Larger homes or irrigation zones may need 3/4 HP. Use the Myers pump curve to place your duty point near the BEP. Add friction losses from elbows and pipe length to your TDH, and confirm amperage draw fits your 115V or 230V circuit. In practice: a 38-foot shallow well with two baths and laundry usually runs perfectly on a 1/2 HP, 115V unit. Rick’s recommendation: choose the smallest HP that meets your GPM at pressure with 10–15% margin; oversizing can push you off BEP and magnify noise and cycling.
2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure? A typical three- to four-person home needs 6–10 GPM. With a shallow well jet pump, pressure is generated by the jet and diffuser combination; with a multi-stage pump (submersible), stacked stages add head per stage. For jets, pay attention to nozzle/venturi sizing and suction integrity—any air reduces effective pressure. For submersibles, more stages create higher head for deeper applications. Myers’ impeller geometry is optimized to hit pressure setpoints efficiently. Rick’s recommendation: aim for 7–8 GPM at 40–50 PSI for most homes; for irrigation, segment zones so your pump stays near BEP.
3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors? In the Predator Plus Series, optimized hydraulics, precision engineered composite impellers, tight wear rings, and a Pentek XE motor keep losses low. When operated near BEP, these pumps deliver 80%+ hydraulic efficiency. The motor’s high-thrust design, thermal overload protection, and lightning protection maintain electrical efficiency and protect windings. For homeowners, this means up to 20% annual energy savings versus less efficient builds. Rick’s recommendation: use PSAM’s curve charts to place your duty point within the flattened sweet spot—don’t oversize and run way left of BEP.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps? 300 series stainless steel resists corrosion from dissolved oxygen, acidic pH, and chlorides far better than cast iron. Components like the shell, shaft, and suction screen stay dimensionally stable, keeping seals true and reducing wear on bushings and bearings. In corrosive water, cast iron pits, which can shed rust scale and degrade sealing surfaces—leading to early failures or micro-leaks in housings. Rick’s recommendation: for variable or aggressive water chemistry, choose stainless-dominant pumps like Myers; your pump will hold tolerance and performance longer.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage? Myers uses Teflon-impregnated staging and self-lubricating impellers made from engineered composites. These materials reduce friction, shed fine grit, and resist abrasion that would otherwise erode vanes and wear rings. Result: sustained pressure, less amp creep, and quieter operation over time. In sandy wells or shallow sources with silt intrusion, this is a major life extender. Rick’s recommendation: if you’re seeing grit in filters, pair a Myers pump with a spin-down sediment filter and schedule annual checks; your impellers will thank you.
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors? The Pentek XE motor delivers higher starting torque and sustained thrust with lower heat rise. Features like improved winding insulation, balanced rotors, and built-in thermal protection and surge mitigation keep efficiency high and protect the motor during voltage fluctuations. In day-to-day use, this translates to smoother starts, less watt draw at set pressure, and longer bearing life. Rick’s recommendation: match voltage correctly (115V or 230V), check amperage draw against the nameplate, and keep wire gauge appropriate for run length to realize the motor’s efficiency.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor? A seasoned DIYer can install a Myers submersible well pump with the right tools and safety practices, but many states require permits and licensed work for potable wells. Key tasks include crimping a proper wire splice kit, setting an internal check valve where appropriate, using a pitless adapter, and verifying pressure switch and tank setup. If you’re replacing a shallow well jet pump, DIY is more common; for deep wells, hire a pro. Rick’s recommendation: call PSAM—my team will review your plan, parts list, and code requirements so you avoid costly mistakes.
8) What’s the difference between 2-wire and 3-wire well pump configurations? A 2-wire well pump houses the start components internally—simpler install, fewer parts, great for most residential needs. A 3-wire well pump uses an external control box with start capacitors and relays, allowing easier servicing of start components without pulling the pump. Myers offers both, so you can choose based on service preference and existing wiring. Rick’s recommendation: for shallow well jets, keep controls simple; for deep wells with longer runs, a 3-wire can simplify future service—PSAM stocks both configurations.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance? With correct sizing, clean power, and normal water chemistry, Myers Predator Plus routinely runs 8–15 years. I’ve seen 20–30 years with ideal conditions, proper filtration, and annual system checks. Keep your pressure tank charged correctly, inspect the check valve, check amp draw yearly, and protect from lightning surges. Rick’s recommendation: schedule a spring check—pressure, amps, and a quick flow test—to catch small issues before they shorten pump life.
10) What maintenance tasks extend well pump lifespan and how often should they be performed? Annually: verify tank precharge, inspect pressure switch contacts, confirm cut-in/cut-out, and check amp draw versus nameplate. Every 2–3 years: evaluate flow rate at a fixed pressure, clean intake screens/filters, and inspect wiring at the wellhead and panel. After storms: check surge protection and listen for new vibration or noise. For shallow wells: recheck suction joints for signs of air ingress. Rick’s recommendation: keep a maintenance log. A 10-minute check saves motors and seals.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover? Myers’ 3-year warranty outpaces many brands that limit coverage to 12–18 months. It covers manufacturing defects and performance failures during normal operating conditions. When combined with PSAM’s support and rapid parts access, homeowners minimize downtime and cost. Competitors with shorter coverage transfer risk back to the owner. Rick’s recommendation: register your product, keep install records, and buy through authorized Myers pump dealers like PSAM to ensure full coverage.
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands? Budget brands often cost less upfront but run 3–5 years on average, especially with thermoplastic housings. Factor two replacements, higher energy use off-BEP, and more service calls—it adds up. Myers’ efficient hydraulics, robust materials, and long warranty reduce replacements and kWh. Over 10 years, Myers typically wins by 15–30% in real costs, not to mention uptime and water quality. Rick’s recommendation: buy once, size right, and maintain annually. It’s cheaper than buying twice.
