Why a Well Point Pump Is the Right Answer for a Shallow Well

If your water table sits within roughly thirty to forty feet of the ground surface, a well point pump is very likely the cheapest, simplest, and most reliable pump you can put in the hole. In two decades of walking test pits, pulling pump strings, and reading static level data on private wells, I have watched a far too many homeowners drop a deep submersible into a well that only needed a well point assembly. The submersible works, but it costs more to buy, more to install, more to pull, and it leaves you with an oversized system for a job that a thirty-six inch well point string could have handled.

This buyer’s guide is aimed squarely at the shallow-well homeowner. You will learn what a well point pump actually is, how it differs from the submersible and jet pumps you may already know, exactly how to size one against your well’s static level and flow, the problems that actually trip homeowners up, and what a proper installation and first-year maintenance should look like. By the end you will know whether the well point pump route fits your well at all, and if it does, how to pick the right one without overpaying.

Key Insight

A well point pump only makes sense when the water level is shallow. If the static water level is deeper than about twenty-five to thirty feet, a well point becomes inefficient and a submersible pump is almost always the better and longer-lasting solution. Measure your water level before you buy anything. That single measurement decides which pump technology fits your well better.

What Is a Well Point Pump and How Does It Work

A well point is a small, sealed, perforated tube that is dropped into a completed well, and a well point pump is the motor that drives water up and out of that tube. The assembly looks and works a little like the suction pipe of an old hand pump, but it is far more refined. The lower end carries a screen or intake strainer that lets clean water into the tube while keeping sand and gravel out. The upper end connects through a flexible hose and a drive shaft to the pump above. When the motor runs, the assembly alternates between pulling an upward stroke of water through the tube and releasing a small charge of air, and the combination of that upstroke and a sealed check valve keeps water moving toward the pressure tank and then into the house.

Because the pump sits above the water and does not push water up from below the way a submersible does, the total depth it can actually lift is limited by the physics of suction. Get the depth wrong and the pump will cavitate, lose prime, and the water will simply not stay in the line. That is exactly why the water-level measurement is the deciding factor, and why a well point pump is specified almost exclusively against wells with a water level in the upper part of the casing.

For a quick, plain-English look at the moving parts and what each one does, the four components that matter are the pump housing with the sealed diaphragm or piston, the well point string down in the water, the sealed check valve that keeps the line in prime, and the flexible hose and drive coupling that connects the string to the motor in the wellhead or well house. Each part is inexpensive on its own and is designed to be replaced without digging or pulling the whole well.

Well Point vs Submersible vs Jet Pump: The Honest Comparison

Most shallow-well owners are deciding between three pump types, and the choice comes down to water level, budget, and how long you want the system to last without a callback. In our experience the deciding factor is always the water level, but the budget and long-term maintenance trade-offs matter too. Here is the honest side-by-side we use when advising a homeowner who has not yet picked a pump.

Factor	Well Point Pump	Submersible Pump	Jet Pump
Best water level	Up to ~25-30 ft	Any depth	Up to ~20 ft
Purchase cost	Low	Highest	Low-mid
Suction limit	Suction-driven	Pushes from below	Suction-driven
Typical motor	1-2 HP	1-1.5 HP	1-1.5 HP
Maintenance access	Above ground	In the well	Above ground
Flow output	Up to ~6 GPM	Up to ~12 GPM	Up to ~6 GPM
Typical life	15-20 yrs	10-15 yrs	10-15 yrs

Figures reflect typical residential systems as of 2026. Your specific well, pump brand, and local code may differ. Always confirm with a licensed installer or inspector.

The takeaway: if your water level stays under about thirty feet and your household flow needs are modest, a well point pump is usually the best value. If you have high flow needs or a deeper well, a submersible pump is the more durable, longer-lasting choice. A true jet pump is only appropriate for the very shallow, high-yield wells that a well point already covers.

Expert Note

In two decades of testing residential wells we have found that a correctly sized well point pump installed to code routinely outlasts a submersible that was dropped in to solve a depth problem it was not designed for. Match the pump to the water, not to the price tag on the box. A modest pump at the right depth will run for years; an oversized pump at the wrong depth will fail early.

How to Size a Well Point Pump Step by Step

This is the part most homeowners rush, and it is the part that causes nine out of ten well point failures. You do not need to be an engineer, but you do need four real numbers and one comparison against the pump rating. Here is the exact sequence we walk a homeowner through during a sit-down sizing session.

The Four Numbers You Need

Static water level — depth to water when the well is at rest (pump off, no one drawing water).
Drawdown — how much the level drops while the pump is running at your target flow.
Total intake lift — static level plus drawdown; this is what your well point must actually pull from.
Peak household flow — the gallons per minute you realistically need, not the pump’s maximum.

Confirm the static water level is under ~30 feet. If it is deeper, stop and reconsider the pump type — a well point pump is not the right tool for a deep well, and you should look at a submersible pump instead.
Add drawdown to get the total intake lift. A realistic drawdown on a shallow well is five to fifteen feet over a continuous draw. Add that to your static level to get the worst-case lift your well point string has to handle.
Estimate your peak flow demand. A single-family home typically runs two to six gallons per minute at the spigot. If you run a pressure tank and a few simultaneous faucets, budget around four to six GPM. Anything above that, or above your well’s measured yield, is a warning sign.
Read the pump rating against your intake lift. Every serious well point pump is rated for a working depth and a corresponding flow. Find the row on the rating chart that matches your total intake lift and confirm the published flow at that depth meets your demand.
Add a margin, not a multiplier. Pick the pump that gives you a couple of GPM above your measured demand at your lift. Do not buy a pump that is three times your need; oversized well points short-cycle and wear out faster than a right-sized one.
Match the hose diameter and check valve. The suction hose should be one size larger than the well point outlet if the lift is pushing the top of the range, and the check valve should be at or below the well head to keep the line in prime.

Common Mistake

Buying the largest motor your well can afford. A 2 HP well point in a well that only needs 1 HP and 5 GPM will short-cycle every thirty seconds, hammer the check valve, and burn the diaphragm within a year. Right-sized is the goal; big is not. For the deeper math, see our guide to total dynamic head and pump sizing.

Well Point Pump Problems and How to Fix Them

Well point systems are forgiving, but they do have a small number of failure modes that are specific to the technology. In our years of servicing them, these are the five problems that come up again and again, in rough order of how often we see them.

Loss of prime. The most common. The line is no longer full of water, usually from a check valve that has allowed air back in. Re-prime the suction line and inspect the check valve seat.
Short-cycling. The pump turns on and off every few seconds. Almost always an oversized pump against a too-large air cushion in the pressure tank, or a pressure switch cut-in / cut-out that is set too close together.
Dry-run burnout. The static level dropped below the well point intake, often after a long dry season. The pump then ran with no water and the diaphragm or motor overheated.
Water loss into the well. The well point screen is clogged with sand, or the casing has a small crack above the screen that leaks. A quick airburst test on the well usually clarifies the cause.
Low flow. The well point is partially buried in silt, the suction hose has an oval kink, or the intake strainer is clogged. A flow test with a simple bucket method tells you how much is coming out now versus at install.

Prevention Routine

Once a year, before the heavy dry season, run the well at your normal flow for five minutes while you measure the pressure tank and watch the drawdown. Log the numbers. When you notice a slow drift over months, that is your early warning that the well’s yield is dropping or the well point is losing prime, long before the pump actually fails on a hot afternoon.

Frequently Asked Questions

How deep can a well point pump actually pull water from?

Practical limit is about twenty-five to thirty feet of suction lift from the water surface. Beyond that, the pump loses prime or efficiency drops sharply, and a submersible pump is the standard solution. That is a physics ceiling on suction, not a marketing number, so any well point rated deeper than that is stretching the physics.

Can a well point pump handle my whole house?

For a single-family home with modest simultaneous demand, yes. A well point rated for four to six GPM at a moderate lift will cover a kitchen faucet, a bathroom, and a washing machine in a normal household. Add a pressure tank sized to the well’s yield and the pump will cycle comfortably. If you run well irrigation, a sprinkler system, or a large household with simultaneous flow, check your peak demand numbers against the well’s measured flow before you buy.

Does a well point need electricity like a submersible?

Yes. A well point pump is an electric motor above the water that drives the piston or diaphragm. The main difference from a submersible is that the motor sits in the well house or pit, which makes it cheaper to service. You still need a standard 120V dedicated circuit, a GFCI, and a pressure switch, so the electrical install is no different from any other household pump.

What happens when the water table drops below a well point intake?

The well point loses water and then air. The pump will start to cavitate, lose prime, and in some cases run dry. That is the single most expensive season-to-season failure on a well point system, and it is exactly why a well point is specified only against wells with a stable, shallow water table. If your well’s static level drifts deeper season-by-season, a well point is not the right long-term pump for you.

How do I know if my well is actually suitable for a well point pump?

Three numbers: a static water level under about thirty feet, a measured flow that meets your household demand at that depth, and a well casing that is sound below the water table. If all three check out during a proper well test, a well point pump is an excellent match. If the static level is deeper than that, or the flow is marginal, a submersible pump for private wells is almost always the better answer.

Installation and Maintenance Basics for a Well Point Pump

A well point pump is one of the easiest well pumps to install and the most common to leave half-done. In our inspection experience, the failures are rarely in the motor. They are in the installation details: the check valve position, the suction hose size, the pressure tank pre-charge, and the well head seal that keeps debris and bugs out. Get those right and the system runs for years with only routine attention.

Confirm the well is sound first. A sound casing below the water table is the foundation. If the casing is cracked or the well has sand in the water, no pump type will make that well safe to drink. Test and treat the water quality question before you spend a day installing a pump.
Prime the suction line before first start. Fill the suction hose and well point string with water so the pump starts with a full line. If the pump is dry at first start, it will hunt for prime and trip its overload relay within seconds.
Set the pressure tank pre-charge correctly. The air side of the pressure tank should be charged about two PSI below the pump’s cut-in pressure. An under-charged tank means the pump short-cycles; an over-charged tank means the tank is doing almost no cushioning work.
Seal the well head and duckbill vent. A dust and bug tight well head cap and a functioning vent valve keep insects, rain, and debris out of the pump chamber. A well point without a sealed head will accumulate grit over the first month of summer.
Run a full-flow test. Open the test spigot to a bucket and time a known volume. That gives you the actual flow rate of the well under load. Log it and compare against the pump rating at your intake lift. That is your first data point for every future drawdown you measure.

Annual Checklist

Once a year, before the dry season: measure the pressure tank pre-charge, verify the well point is still seated, test the check valve for leaks by shutting the pump off and watching for a pressure drop, and confirm the well head cap is sealed. Ten minutes of routine checks beats a two-hour call on a ninety degree day.
