Why is my shallow well pump running but no water?

If your shallow well pump is running but no water is coming to the house or irrigation line, the problem is usually in the pump, suction line, foot valve, prime, or the well itself, not just the pump motor.

Common reasons a shallow well pump runs with no water

A shallow well pump can sound like it is working and still fail to deliver water. In Central Florida, the most common causes are loss of prime, air leaks on the suction side, a clogged screen or foot valve, a low water table, or a pump that has worn enough to lose lift.

Here are the issues we check first:

• Pump lost prime, the pump housing is full of air instead of water.
• Air leak in the suction line, even a small leak can stop the pump from lifting water.
• Clogged foot valve or screen, sand, debris, or mineral buildup can block flow.
• Damaged impeller or worn pump parts, the pump may run but not move enough water.
• Water level dropped below pump capacity, shallow wells depend on local groundwater conditions.
• Electrical or pressure-control problem, the motor may run, but the system may not be operating correctly.

If you are dealing with a shallow well on a property in Polk County or nearby, we can diagnose the full system, not just the pump. Dunham Well Drilling handles pump repair and installation and shallow 2-inch irrigation wells, so we can trace the problem from the well to the pressure tank.

What to check before you call a well contractor

There are a few basic things a homeowner can look at safely.

Look for signs the pump is losing prime

If the pump has been running dry, surging, or making a different sound than usual, it may have lost prime. A shallow well pump needs a solid water column to create suction. If air gets into the line, the pump can run without moving any water at all.

You may also notice:

• sputtering at the faucets
• low or no pressure
• a pump that starts and stops repeatedly
• visible air in the water line when water briefly returns

Check whether the problem is only at one fixture

If one faucet is dry but other parts of the system work, the issue may be isolated to plumbing rather than the well. If the entire house or irrigation zone has no water, the problem is more likely in the pump, suction line, pressure tank, or well.

Do not open electrical components or pressure tank fittings yourself. If the pump is not delivering water, call for service.

Why shallow wells in Central Florida can stop producing

Shallow wells are common for irrigation in our area, but they depend heavily on the local water table. In Polk County, the water level can shift with weather, seasonal demand, and site conditions. A shallow well that worked for years can start acting up if the water level drops or if the intake area begins pulling in sediment.

That is one reason we evaluate whether a shallow irrigation well is still the right setup for the property. Sometimes the fix is a repair. Sometimes the pump size needs to be corrected. In other cases, the well itself may no longer be a reliable source for the demand it is serving.

Pump, tank, or well: how we narrow it down

When a customer calls about a shallow well pump running but no water, we start by separating the problem into three parts: the pump, the pressure system, and the well.

Pump-side problems

A pump may need repair if the internal parts are worn, the seals have failed, or the suction side is leaking air. Dunham’s pump repair and installation service includes residential pumps, irrigation pumps, and pressure tanks, and we have a full-line machine shop for in-house rebuilds.

That matters when a pump can still spin but cannot move water. In many cases, the unit needs more than a quick adjustment.

Pressure system problems

A failed pressure tank, switch issue, or control problem can make a system act dead even when the pump itself is still serviceable. We also handle pressure tank work as part of pump service.

If lightning has damaged the control side of the system, our lightning damage repair service can help with pump and motor repair, pressure-switch replacement, and related well-system electrical issues.

Well or water-source problems

If the pump is working and the pressure parts are fine, the well may simply not be supplying enough water. That can happen with shallow wells, especially when the water table changes or the well has sediment at the intake.

In some cases, drilling a new well may be the better long-term answer. Dunham provides water well drilling for residential, agricultural, and commercial properties across Central Florida, including 2-inch shallow irrigation wells and deeper wells for drinking water and high-volume use.

When the water itself may be the clue

If water returns briefly and then stops again, or if the water is rusty, sandy, or smells bad, the issue may involve the well intake or water quality rather than only the pump. Heavy iron, sulfur smell, or sediment can indicate that the system needs both pump work and treatment.

We also provide water filtration and treatment for hard, smelly, or staining well water. Because we do both pump and filter work, we can look at the whole system instead of sending you to two different companies.
