How do I know if my shallow well pump is bad?

If you’re wondering whether your shallow well pump is bad, the usual signs are weak pressure, no water, air spurting from the taps, or a pump that runs but never seems to build pressure.

Common signs a shallow well pump is failing

A shallow well pump can give you a few warning signs before it stops working completely. The most common one is loss of water pressure. If your faucets and hose bibs suddenly act weak, or the pump seems to cycle more often than it used to, the pump, pressure switch, tank, or well supply may need attention.

Other signs include:

• Pump runs but no water comes out
• Low or inconsistent water pressure
• Air in the water lines
• Pump keeps turning on and off
• Pump hums, buzzes, or trips the breaker
• Water delivery is fine one day and poor the next

If the problem started after a lightning storm, the issue may be electrical. We handle lightning damage repair for well systems, including pump and motor repair, pressure-switch replacement, and control work.

Shallow well pump bad or something else?

Not every water problem means the pump itself is bad. On a shallow well system, the trouble can also come from the pressure tank, foot valve, switches, wiring, or the well’s water level.

Pressure tank and switch problems

A bad pressure tank can make a good pump act like it is failing. If the tank is waterlogged or the pressure switch is worn out, the pump may short-cycle or fail to maintain pressure. That is not a DIY situation when electrical service is involved. Call us and we can test the system safely.

Air leaks and suction issues

A shallow well pump depends on a solid suction line. If there is an air leak, cracked pipe, loose fitting, or faulty foot valve, the pump may lose prime and stop pulling water. You may hear the pump running, but the faucet flow will be poor or nonexistent.

Well supply or water table changes

Sometimes the pump is fine, but the well cannot keep up. In parts of Polk County, shallow wells can be a practical irrigation choice, but they still depend on the local water table. If the water level drops too far, the pump can start pulling air instead of water.

If your system is used for lawn watering, our shallow (2-inch) irrigation wells page explains the kind of shallow well work we do across Central Florida.

Quick checks before you call

You can notice the symptoms, but you should not start taking apart the pump, pressure tank, or electrical controls yourself. Those parts can be hazardous.

Here are a few safe things to observe:

• Is the pump running continuously?
• Is there water at any faucet at all?
• Did the problem start after a storm?
• Is the pressure weak everywhere or only at one fixture?
• Do you hear humming, clicking, or breaker trips?

If you have a pump that hums but will not start, or a system that loses prime repeatedly, the pump may be worn out or there may be another problem in the well system. Either way, it needs a proper diagnosis.

How we diagnose shallow well pump problems

At Dunham Well Drilling, we work on pump repair and installation every day, and we also have a full-line machine shop for in-house rebuilds. That matters because some pump problems can be repaired, while others need replacement parts or a rebuilt component.

We service:

• Residential jet and submersible pumps
• Irrigation pumps
• Pressure tanks
• Centrifugal pumps
• Industrial and turbine pumps

We also carry Goulds, Sta-Rite, Grundfos, and Schaefer new and used. If the pump is repairable, we can often rebuild it in-house rather than sending you somewhere else.

When a shallow well pump is probably bad

A shallow well pump is more likely to be the problem when:

• The motor runs but the pump cannot build pressure
• The pump is old and has had repeated problems
• The breaker trips again after being reset
• The unit is noisy, overheating, or losing prime often
• There is visible corrosion, water damage, or storm damage

In some cases, the pump is not the only issue. A failing pressure switch, tank, or foot valve can make the whole system seem bad. That is why proper testing matters before replacing parts.

If your well also needs water quality help, we offer water filtration & treatment for hard water, iron, rotten-egg odor, and staining. We can test the water on site and help match the treatment to the actual problem.
