5 Signs Of Submersible Well Pumps Malfunctions

Submersible well pumps are enclosed systems and thus have a long productive lifespan. However, when the seal corrodes over time, water seeps in and causes the motor to fail. As a result, you get several telltale symptoms that point you towards underlying system malfunctions. Signs that indicate your submersible well pump is problematic are discussed below.

1. The Pump Starts Up Too Much

Your pump starts when you use a considerable amount of water, like when you shower or flush the toilet. However, when you want to fill the icemaker or wash your hands, your pump shouldn't necessarily start. Problems that cause your pump to start too often include :

  • The pressure tank leaks above the water level
  • The pressure switch is defective or not adjusted accordingly
  • Leaks in the discharge line check valve, etc.
  • The air volume control has malfunctioned

Based on the intensity of the underlying problem, you will need to repair, replace some parts, or get a new pump.

2. Sudden Pump Failure

A sudden submersible well pump failure isn't a common problem. Most of the time, water problems that call for well repair also affect your pump's operations. For example, drought lowers the water level in your well and reduces water flow. In such cases, your water well expert hydro fractures or lowers your well pump deeper to improve replenishment rates.

3. No Water at The Faucets

If your faucets don't have water, first check your circuit breaker. If the circuit breaker is switched off, switch it on and check your water again. If you still don't get water, you might have a problem with the pressure switch on your storage tank or the pump. Contact a professional if you have or suspect electrical issues with your water pump.

4. Abrupt Change in Water Quality

When sediment enters your pump, the efficiency of your well pump declines, and your water quality declines. The sediment causes your well pump to work harder and creates corrosive conditions that wear down your pump's internal elements. As a result, you get muddy, cloudy, or discolored water.

5. A Spike in Utility Bills

If your well pump works overtime, your electricity consumption increases hence a rise in power bills. Several underlying problems cause your well pump to run constantly. Such problems include holes in the drop pipe, damaged foot valves, and pump leaks.


The most effective way to maintain your well pump is to schedule regular inspections with your well professional. Early diagnosis of a problem often results in lower-cost repairs instead of costly replacements. Other than the pump, your trusted expert inspects the well, pressure tank, pipes, and electrical connections.
