A sudden spit of air, faucets coughing, pressure gauge bouncing, then the hard stop—no water. If you’ve ever lived on a private well, you know that feeling in your gut when the shower turns cold and the kitchen sink wheezes. Air in a water system is more than a nuisance. Left unresolved, it scorches motors, burns contacts, hammers pipes, and destroys pumps long before their time. I’ve pulled more than a few submersibles that died only because air entrapment was allowed to persist.
Two Thursdays ago, during a humid Ohio afternoon, I took a call from the Álvarez-Torrance family outside Zanesville. Gabriela Álvarez (38), a public school nurse, and her husband, Evan Torrance (41), a self-employed electrician, live with their kids Mateo (9) and Lia (6) on 6.7 acres. Their 240-foot private well with a 1 HP 10 GPM submersible had been sputtering for weeks. Their outgoing pump, a 1 HP budget unit from a big-box brand, would short cycle, lose prime at the tank tee, and rattle the pipes each morning. It finally quit after a scorcher of a weekend watering the garden. Evan found the pressure gauge swinging wildly; the check valve hissed; and the water line burped air. Classic air entrapment plus a failing motor.
This guide is for rural homeowners and contractors who need fast, no-nonsense solutions. We’ll cover: how air gets in, how to purge it, what components prevent it, why Myers Predator Plus submersibles solve it, how to size properly, how to set tanks and pressures right, when to go 2-wire vs 3-wire, and what field-serviceable features save you when a fitting or seal compromises the system. If you simply need the right kit today, myers deep well water pump PSAM ships Myers Predator Plus fast—getting your well flowing without repeat service calls.
Let’s dig in.
#1. Find the Air Source First — 300 Series Stainless Steel Integrity Meets Smart Diagnostics with Predator Plus Series
Air in a closed well system always has a path. Identify it quickly, and you’ll protect the motor, restore steady flow, and stop destructive cycling. Most common culprits: a compromised drop-pipe fitting, a pinhole in poly line, a leaky pitless O-ring, or a failing top-side check valve drawing air when the column drains.
Under the well cap, a high-quality 300 series stainless steel pump body and discharge stack resist crevice corrosion that can open micro-channels for air. On Myers Predator Plus Series submersibles, the stainless discharge bowl, suction screen, and shaft coupling keep geometry true and leak paths at bay. Combined with the factory threaded assembly, you get precise sealing surfaces that tolerate service, not just one-time installs. When paired with a sound check valve plan (more on that below), air infiltration points are eliminated before they start.
Gabriela Álvarez’s sputter wasn’t random. Evan’s visual showed a dripping pitless union and a top check valve seeping back. Air seeped in as the line drained, then purged violently on every call. After a new pitless O-ring and a PSAM drop-pipe kit matched to the 1-1/4" NPT discharge, their system stabilized.
Where Air Hides in a Well System
Micro-leaks at threaded fittings, especially galvanized to brass transitions, are notorious. Look at the tank tee, gauge, boiler drain, and pressure switch port. In the well, inspect the first 20 feet of drop pipe for rub marks and pinholes, especially if the safety rope or cable guard is missing.
How Stainless Components Help
Corrosion pits grow where water chemistry is aggressive. 300 series stainless steel resists that, maintaining smooth sealing faces and preventing vacuum draw at joints. Myers’ stainless discharge bowl and intake screen hold up in mineral-rich water where cheaper alloys fail.
Pressure Test to Confirm
Lock out power. Install a pressure plug at the tank tee and a test gauge downstream. Pump to 60 psi. Isolate zones. Any pressure decay points to a leak path—fix before running the motor again. A 10-minute test often saves a pump.
Key takeaway: Stop air at the source. Myers’ stainless geometry and tight machining reduce leak paths and make sealing predictable.
#2. Purge Entrained Air Fast — Predator Plus Hydraulics, Internal Check Valve, and Correct Tank Sizing
When air’s trapped in lines, it compresses and expands under demand, making pressure control impossible. Purge it clean, then keep it out with the right components. Myers submersible well pump hydraulics move an honest column of water thanks to engineered composite impellers and precision staging, so once the line is sealed and primed, air gets swept out quickly.
On Predator Plus models, the optional factory internal check valve at the discharge keeps the column from draining back. Add one external spring-loaded check at the tank, not a dozen sprinkled up the line. Too many checks trap air pockets. Too few and you vacuum-draw through fittings during recovery.
The Álvarez-Torrance system was under-tanked for their usage. A 20-gallon tank with only ~5-6 gallons drawdown at 40/60 was too small for laundry plus irrigation. We bumped them to a 44-gallon tank (about 12 gallons drawdown) so the pump cycles are slower and air purge is thorough after service.
Right-Fit Pressure Tank
Match drawdown to demand. For a 10 GPM pump at 40/60, aim for 10-14 gallons drawdown. That’s typically a 44-62 gallon rated tank. More drawdown equals longer purge time per cycle and quieter lines.
Bleed and Flush Procedure
Open the highest fixture first, then mid-level, then lowest. Let it run steady until all spitting stops. If you’ve replaced fittings, repeat. Avoid rapid on/off cycles during purge.
Check Valve Strategy
One quality check at the pump discharge (internal on Myers or an external stainless spring check) and one at the tank tee. Don’t stack checks up the riser; they trap air segments.
Key takeaway: Right-size the tank, place checks wisely, and let Myers’ staging sweep out air cleanly.
#3. Set Pressure Correctly — Pressure Switch, BEP Alignment, and Pentek XE Stability
Incorrect pressure differentials can induce air issues by forcing short cycling and turbulent flow that whips air into solution. Set your pressure switch thoughtfully. For most homes, 40/60 is ideal; for shallow systems or low-yield wells, 30/50 reduces stress. Predator Plus pumps perform best near best efficiency point (BEP)—that’s where you get smooth hydraulics and fewer entrainment headaches.
The Pentek XE motor on Myers Predator Plus delivers high thrust with consistent torque, helping the pump hit target pressures without overshoot. With thermal overload protection and lightning protection, it rides through tough starts and voltage dips without shaking the column or cavitating. Stable motors mean stable hydraulics, which mean fewer bubbles and cleaner flow.
Once Evan recalibrated to 40/60 and set the tank precharge to 38 psi (2 psi below cut-in), the gauge stopped swinging and the faucets ran steady. Smooth control starts at the switch.
Pressure Switch Tuning
- 30/50 for older plumbing or marginal wells. 40/60 for most residential systems. Adjust evenly: increase both cut-in and cut-out together to maintain a 20 psi differential.
Precharge Matters
Always set tank precharge 2 psi below cut-in. Check with power off and system drained. Wrong precharge equals rapid air ingestion at fixtures and rumbles at start-up.
BEP and Air Reduction
Operating near BEP (where the pump curve and household demand intersect) promotes laminar flow and reduces vortexing that sucks in micro-bubbles at fittings.
Key takeaway: Solid pressure control plus a Pentek XE-backed curve equals quiet lines and no air chatter.
#4. Eliminate Suction-Side Air on Jet Systems — Myers Jet Pump Priming, Well Seal, and Drop Pipe Integrity
Air problems aren’t just for submersibles. Any jet pump—shallow or convertible—lives and dies by its ability to hold prime. A loose well seal, a tired foot valve, or a hairline crack on the drop pipe will invite air every time the pump rests. Myers jet pump designs make priming straightforward, and when matched with correct nozzle/venturi setups, they move water without froth.
Unlike submersibles that push, jet pumps pull. That negative pressure is unforgiving to tiny leaks. A Myers jet running at 30/50 with a proper foot valve and fresh suction line will purge air once and hold it for seasons. If you’re swapping from a sputtering shallow setup to a submersible, Myers deep well pump options with 1/2 to 1 HP submersible bodies remove suction leaks from the equation entirely.
The Álvarez-Torrance family used a submersible, but I see weekly calls where a convertible jet with a cracked PVC nipple on the suction side was the sole cause of “mystery” air. Fix that one joint, and the spitting stops.
Prime and Pressure Test a Jet Pump
Fill the casing completely. Bleed the high point. Install a gauge on the suction line for a 10-minute static check. If pressure bleeds off, air is entering somewhere.
Upgrade the Well Seal
Use a heavy-duty, correctly sized well seal. Lubricate the rubber properly. Tighten evenly. A crooked seal is a permanent air straw.
Drop Pipe Materials
Use continuous poly with stainless insert fittings and double clamps, or schedule 80 PVC glued properly. Avoid cobbled sections with mismatched threads.
Key takeaway: On jet systems, suction integrity is everything. Myers jets prime and hold when the suction side is airtight.
#5. Choose Impellers That Don’t Shred Air — Teflon-Impregnated Staging, Engineered Composite Impellers, and Smooth Purge
Entrained air accelerates wear. Bubbles implode under pressure (micro-cavitation), pitting impellers and diffusers. Myers uses Teflon-impregnated staging and self-lubricating impellers designed to survive the occasional air slug while moving grit-laden water better than standard plastics. That material choice and geometry matter when you’re clawing back from a leak event.
Once a submersible ingests air, the pump’s efficiency drops sharply. Many budget impellers heat, swell, and drag. Myers’ engineered composite staging stays stable, reducing friction spikes and power draw while you flush lines. This is a tangible reason I recommend Predator Plus when customers are recovering from air entrapment events or dealing with seasonal level dips.
Mateo and Lia turned on the outdoor spigot mid-purge like kids do. No harm done—the Predator Plus staging tolerated the brief churn, kept amperage within spec, and finished the job.
Material Science That Pays Off
Teflon-impregnated staging reduces wear when lubricity is marginal (air, fine sand), preserving clearances so hydraulic efficiency rebounds quickly after purge.
Amperage Draw Monitoring
Check running amps after service. A smooth-impeller set returns to nameplate amps quickly. If you’re 10-15% high, recheck for remaining air or partial blockage.
System Recovery
After a repair, run a full cycle to 60 psi and a full drawdown to 40 psi while monitoring flow and noise. Silence is your friend.
Key takeaway: Myers’ staging tolerates the real world—brief air slugs, minor grit—without wrecking your pump during recovery.
#6. Wire It Right, Size It Right — 230V Single-Phase, 2-Wire vs 3-Wire, and TDH on the Pump Curve
Undersized conductors and mis-sized pumps invite nuisance cycling, voltage sag, and—in worst cases—intermittent stalling that churns air into the flow. Myers Predator Plus offers 2-wire and 3-wire models across 1/2 HP to 2 HP in https://www.plumbingsupplyandmore.com/convertible-shallow-well-jet-pumps-1-2-hp.html 230V single-phase. For most homes up to 200-300 feet and 8-12 GPM needs, a 2-wire 230V simplifies installation and removes an external control box from the troubleshooting tree.
Always size to TDH (total dynamic head): static water level, drawdown during pumping, plus friction loss, plus desired pressure (convert psi to feet: psi x 2.31). Plot this on the Myers pump curve. Run close to the middle-third—your BEP—and you avoid cavitation that pulls air at fittings.
For the Álvarez-Torrance well: static at 120 feet, drawdown to 160 feet at 10 GPM, plus 20-30 feet friction and 60 psi (about 138 feet). TDH ≈ 318 feet. A Myers 1 HP 10 GPM stack sitting near center of its curve at that head is right on the money.
2-Wire vs 3-Wire
- 2-wire well pump: Fewer components, faster swaps, fewer failure points on emergencies. 3-wire well pump: External control box accessibility for capacitor replacement; handy in some service contexts.
Wire Gauge Matters
At 230V, voltage drop should stay under 5%. Use a gauge calculator; long runs often need 10 AWG or 8 AWG for 1-1.5 HP at depth.
Start and Run Stability
A Pentek XE motor handles start loads without wild inrush spikes. That stabilizes pressure on startup and reduces entrainment risks.
Key takeaway: Put the pump on the right curve, use the right wire, and air problems often vanish with the sizing mistakes that caused them.
#7. Pinpoint vs Broad Comparisons — Why Myers Predator Plus Beats Goulds and Grundfos in Air-Problem Scenarios
When air entrapment is part of your story, materials, motor behavior, and serviceability determine how fast you recover and how long your fix lasts.
- Technical performance: Myers Predator Plus uses 300 series stainless steel throughout the shell, discharge bowl, and suction screen, with engineered composite impellers and Teflon-impregnated staging to resist cavitation pitting. The Pentek XE motor delivers high thrust with efficient torque, helping the pump maintain flow through transient air conditions. Efficiency is excellent near BEP, routinely 80%+ hydraulically at the sweet spot. Real-world application: In acidic or high-mineral water, I routinely see Goulds Pumps with cast iron components show corrosion at mating surfaces that complicate sealing and can draw air on restarts. Some Grundfos deep-well packages lean toward 3-wire control complexity, adding initial cost and another point to troubleshoot when air causes rapid short cycles. On-site field service is faster on the Myers threaded assembly; you don’t need proprietary dealer-only kits. Value conclusion: If air has burned you once, stepping into Predator Plus with PSAM support, stainless build, and the 3-year warranty saves repeats. The reliability, serviceability, and efficiency make the upgrade worth every single penny.
#8. Accessory Choices That End Air Trouble — Pitless Adapter, Torque Arrestor, Cable Guard, and Wire Splice Kit
You can buy the perfect submersible and still end up with air problems if the accessories cut corners. Use a heavy-duty pitless adapter with fresh O-rings. Install a torque arrestor to prevent start-up twist that loosens joints. Add cable guards every 20 feet to stop insulation rub-through on the casing, and use a heat-shrink wire splice kit designed for submersible duty.
On PSAM Myers installs, I package a stainless pitless, torque arrestor, safety rope, and double-stainless clamp protocol for poly risers. Tight accessories stop rub leaks and vacuum pathways that feed entrained air after shut-off.
For Evan’s drop-pipe rebuild, we used a PSAM fittings kit with stainless inserts and dual clamps, heat-shrink splices, and fresh guards. The first start-up was clean—no rattle, no spit—just 10 GPM steady to 58-60 psi.
Pitless Refresh
Replace the seal any time the pump comes up. Clean mating faces. A nicked O-ring can undo a day’s work with mystery air 48 hours later.
Torque Management
A torque arrestor centered just above the pump stops kicking and keeps fittings from loosening—especially critical on poly.
Splice Integrity
Heat-shrink, adhesive-lined splices rated for submersible duty are non-negotiable. Tape-only splices are invitations to air and shorts.
Key takeaway: Accessories aren’t extras—they’re the air-proofing backbone of your installation.
#9. Warranty and Service Life — 3-Year Warranty, Field Serviceable Threaded Assembly, and PSAM Ship-Now Support
Air-related failures often show up as motor overloads and bearing damage months after the leak began. That’s why premium build and strong backing matter. Myers Predator Plus carries an industry-leading 3-year warranty, with American-made consistency and field serviceable design using a threaded assembly. You don’t junk a good pump for a small issue—you service it.
At PSAM, we ship Predator Plus and accessory kits same-day on in-stock items. For emergency buyers like Gabriela facing no water on a school night, that speed is not a luxury—it’s survival. When done right, Predator Plus submersibles deliver 8-15 years, and with excellent care, 20-30 years isn’t a fairy tale; I’ve seen it.
The Álvarez-Torrance family? We expect a decade-plus. No mystery air. No yo-yo gauges. Just a quiet, efficient pump that pays down the upgrade with lower bills and zero service calls.
Field Service Advantage
The threaded assembly allows in-well service by any qualified contractor. You’re not captive to dealer-only tear-downs.
Certifications That Count
NSF/ANSI, UL listed, CSA certified—and every pump is factory tested. That translates to dependable starts and predictable curves.
PSAM Support
Spec sheets, curves, and parts are a phone call away. We match tanks, checks, fittings, and wire so nothing compromises your air seal.
Key takeaway: Strong warranty plus serviceable design isn’t marketing—it’s long-term cost control.
#10. Smart Savings vs. Shortcuts — Why Myers Outlasts Red Lion and Franklin Electric in Real Air-Fix Installs
- Technical performance: Myers’ stainless steel shells and discharge components shrug off pressure cycling that can crack thermoplastic housings commonly used by mid-range brands like Red Lion. Meanwhile, the Pentek XE motor holds thrust and temperature under control during purge events. With 80%+ hydraulic efficiency at BEP, energy consumption stays lean even when recovering from a service. Real-world difference: I’ve replaced more than a few Red Lion submersibles that developed housing stress cracks after repeated pressure shock, letting air back in. On some Franklin Electric packages, proprietary control boxes and dealer networks can slow field service—especially when air entrapment causes rapid cycling and component burnout. Myers’ 2-wire configuration option trims complexity and speed-to-water by eliminating that external control box on many residential installs. Value conclusion: For a homeowner trying to end the “spit-and-spike” cycle and for contractors who need one-and-done reliability, Myers delivers materials, motor, and serviceability that actually solve air problems—worth every single penny.
FAQ: Myers Predator Plus and Air Entrapment — Rick’s Expert Answers
1) How do I determine the correct horsepower for my well depth and household water demand?
Start with your TDH: static level + drawdown during pumping + friction loss + pressure requirement (psi x 2.31). Then match flow. Most homes run well at 8–12 GPM. For example, a 240-foot well with 160 feet pumping level, ~30 feet friction, and 60 psi at the house (138 feet) equals ~328 feet TDH. On the Myers curve, a 1 HP 10 GPM submersible often sits right at the BEP around 320–340 feet. A 1/2 HP suits shallow systems at 60–120 feet TDH; 1.5 HP steps up for 350–450 feet TDH or higher flows. My recommendation: choose the model that places your operating point in the middle third of the curve. It reduces cavitation, lowers amp draw, and prevents the air-laden turbulence that destroys stages.
2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
Most homes do fine at 8–12 GPM. Homes with irrigation, livestock, or multiple bathrooms under simultaneous use may need 12–16 GPM. A multi-stage pump increases pressure by stacking impellers—each “stage” adds head. Myers Predator Plus offers 7–15+ stages depending on HP and target flow. More stages at a given flow equals higher head, meaning you hit 50–60 psi comfortably even at deeper pumping levels. With predictable staging and engineered composite impellers, you get consistent pressure without the air-whipping surges you see in under-staged setups. Pro tip: Match your stage count so your duty point sits just right—smooth, quiet, and efficient.
3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
It’s the synergy of tight-tolerance diffusers, Teflon-impregnated staging, and the Pentek XE motor delivering true thrust at speed. Less slip between impeller and diffuser means more water per watt. On the curve, many Predator Plus models hit the 80%+ hydraulic efficiency window at their BEP, slashing energy use by up to 20% versus generic 10 GPM sets. Efficiency isn’t just about bills—it’s about smoother flow. Efficient hydraulics reduce eddying that entrains micro-bubbles at fittings, so after an air event, the system purges faster and stays stable.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps?
Submersibles live in an oxygen-poor, mineral-rich environment where cast iron invites scale, rust, and pitting at joints and fasteners. 300 series stainless steel maintains clean sealing faces, preventing micro-channels that can vacuum-draw air through drain-back events. It also resists acidic water and chloride attack better than mixed-metal builds. In the field, stainless keeps geometry intact for years, so check-valve sealing stays predictable and your discharge stack doesn’t become an air straw. Myers uses stainless on the shell, discharge bowl, shaft coupling, wear ring, and suction screen for maximum corrosion resistance.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
Grit plus air equals hot, dry friction. Teflon-impregnated materials lower the coefficient of friction during marginal lubrication—like the first minutes after a repair when air hasn’t fully purged. That keeps clearances tight, prevents stage scoring, and stabilizes amp draw. In my service logs, Predator Plus impellers hold their edges longer than generic plastics in sandy wells. The payoff: fewer efficiency losses over time, less noise, and a much lower chance of stall when air sneaks in during extreme drought drawdowns.
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
High-thrust bearings, optimized rotor/stator design, and better heat management. The Pentek XE motor sustains thrust loads from multi-stage stacks at depth without dragging, so it holds RPM and torque as designed. Add thermal overload protection and lightning protection, and transient events don’t cook windings or distort performance. Stable motor speed equals stable pressure. When you’re chasing air, that stability helps the system purge predictably instead of surging.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor?
Experienced DIYers can install with care, but respect the details: correct wire gauge, waterproof wire splice kit, pitless adapter alignment, proper torque arrestor placement, and safe well handling. Always size via TDH and follow local code on well cap and electrical. For deep sets (200–500 feet) or when cranes/hoists are required, hire a licensed well contractor. The Myers advantage is a field serviceable design—if you’re qualified, threaded assemblies and common tooling make service straightforward. If you’re unsure, call PSAM. We’ll spec parts and connect you with a pro.
8) What’s the difference between 2-wire and 3-wire well pump configurations?
A 2-wire submersible has start components integrated in the motor—clean install, fewer parts, fast swaps, and fewer failure points. A 3-wire uses an external control box with capacitor(s), which can be serviced topside. For most residential wells up to about 1.5 HP, 2-wire 230V is my go-to for simplicity and reliability—especially when solving air issues where fewer components mean fewer places for cycling wear. If service accessibility is a priority or you’re matching existing wiring and box, 3-wire remains a fine option with Myers Predator Plus.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance?
With correct sizing, good water chemistry, and proper accessories, expect 8–15 years. I have plenty of Myers installs over 18–22 years that still hit pressure quietly. The keys: right pressure tank sizing and precharge, annual pressure switch inspection, a single high-quality check valve strategy, and protection from voltage sag. After any suspected air event, flush fully and verify amps vs nameplate. That diligence makes 10+ years routine rather than lucky.
10) What maintenance tasks extend well pump lifespan and how often should they be performed?
- Annually: Test tank precharge (power off, drain system), clean pressure switch contacts if pitted, confirm pressure settings, and inspect gauge accuracy. Every 2–3 years: Inspect pitless alignment and seals; verify ground continuity and insulation resistance on motor leads. After any plumbing work: Purge air fully from highest to lowest fixture; recheck for leaks and amp draw. During droughts: Monitor recovery rate to avoid running the pump at excessive drawdown. A few simple checks replace service calls with peace of mind.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers’ 3-year warranty outlasts the 12–18 months offered by many brands. It covers manufacturing defects and performance failures within standard operating conditions. When a system has been correctly sized and installed, I see minimal claims—which is the point. Between stainless construction, Pentek XE motors, and factory tested assemblies, the warranty is less safety net and more proof of confidence. PSAM assists with documentation, parts identification, and expedited replacements when eligible.
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Add purchase price, installation time, parts, energy, and downtime risk. A Predator Plus operating near BEP can trim energy use ~20% annually. Over 10 years, that’s hundreds—often thousands—saved. Budget pumps frequently die at 3–5 years; two replacements plus repeat labor and downtime outstrip a single Myers install with a 3-year warranty and 8–15 year expectancy. Factor in fewer service calls and stronger resale narratives for your property, and the Myers route is cheaper in real life, not just on paper.
