Water Pump Not Working: Causes, Troubleshooting, and Solutions


A water pump is an essential component of any plumbing system. It is responsible for circulating water in your home, supplying water to your appliances and fixtures, and maintaining water pressure. However, like any other mechanical device, a water pump can fail or malfunction, leaving you with low water pressure or no water at all. In this article, we will discuss the causes of a water pump not working, how to troubleshoot the issue, and the possible solutions.

Understanding Your Water Pump

Before we dive into the causes of a water pump not working, it’s important to understand how it works. A water pump typically consists of a motor, an impeller, and a housing. The motor drives the impeller, which in turn, creates pressure and circulates water through the housing and into the pipes. The pressure created by the impeller is what allows water to flow through your plumbing system and reach your faucets and appliances.

Causes of a Water Pump Not Working

There are several reasons why a water pump may stop working, including:

Electrical Issues

One of the most common causes of a water pump not working is electrical issues. The motor that drives the impeller requires electricity to function, and if there is an issue with the electrical supply, the pump will not work. Electrical issues can be caused by a blown fuse, a tripped circuit breaker, a faulty motor, or a damaged power cord.

Low Water Level

A water pump requires a certain level of water to function properly. If the water level in the well or reservoir is too low, the pump may not be able to draw water, which can cause it to stop working.

Clogged Impeller

The impeller is responsible for creating pressure and circulating water through the pump. If the impeller becomes clogged with debris or mineral buildup, it may not be able to function properly, which can cause the pump to stop working.

Pressure Switch Issues

The pressure switch is a component of the water pump that turns the pump on and off when the pressure in the system reaches a certain level. If the pressure switch is not functioning correctly, it may not be able to turn the pump on, which can cause the pump to stop working.

Faulty Check Valve

A check valve is a one-way valve that prevents water from flowing back into the well or reservoir. If the check valve is faulty, water may flow back into the well or reservoir, which can cause the pump to lose its prime and stop working.

Troubleshooting a Water Pump Not Working

If your water pump has stopped working, there are several steps you can take to troubleshoot the issue.

Check the Power Supply

The first step is to check the power supply. Make sure that the pump is receiving electricity by checking the fuse, circuit breaker, power cord, and motor.

Check the Water Level

If the power supply is not the issue, check the water level in the well or reservoir. Make sure that the water level is high enough to allow the pump to draw water.

Inspect the Impeller

If the water level is not the issue, inspect the impeller for any debris or mineral buildup. Clean the impeller if necessary.

Check the Pressure Switch

If the impeller is not clogged, check the pressure switch. Make sure that it is functioning correctly and turning the pump on and off at the right pressure levels.

Inspect the Check Valve

If the pressure switch is not the issue, inspect the check valve for any faults. Replace the check valve if necessary.

Solutions for a Water Pump Not Working

If troubleshooting your water pump does not resolve the issue, there are several solutions you can consider.

Replace the Pump

If none of the troubleshooting steps work, it may be time to replace the pump. A water pump that is beyond repair or has reached the end of its life may need to be replaced with a new one.

Hire a Professional

If you’re not comfortable troubleshooting or replacing the water pump on your own, it’s best to hire a professional. A licensed plumber or pump technician can diagnose the issue and recommend the best course of action.


A water pump not working can be a frustrating and inconvenient problem to deal with. However, by understanding the causes and troubleshooting steps, you can quickly identify the issue and get your pump working again. If you’re not comfortable handling the issue on your own, don’t hesitate to call a professional for help.

Why does my water pump keep turning on and off?

This issue is likely caused by a faulty pressure switch or a waterlogged tank. It’s best to call a professional to diagnose the issue and recommend a solution.

How often should I replace my water pump?

The lifespan of a water pump can vary depending on usage, maintenance, and other factors. However, on average, a water pump should last between 8 to 15 years.

How can I prevent my water pump from failing?

Regular maintenance, including cleaning the impeller, checking the electrical supply, and monitoring the water level, can help prevent water pump failure.

Can a water pump be repaired, or does it need to be replaced?

In some cases, a water pump can be repaired if the issue is minor. However, if the pump is beyond repair or has reached the end of its life, it may need to be replaced.
