What to Do When Your Water Pump Fails

If your water pump has failed, it can be a stressful and confusing time. But don’t worry, with a little bit of knowledge and some basic tools, you can fix the problem yourself. Here are some steps to take and precautions to keep in mind when dealing with a failed water pump.

Step 1: Identify the Problem

Before you start working on the water pump, it’s important to understand what’s causing the failure. Is the pump not turning on at all? Is it making strange noises or leaking? Knowing the symptoms of the problem will help you determine the cause and choose the right solution.

Step 2: Turn off the Power

Before you begin working on the water pump, be sure to turn off the power to the pump. This can usually be done by switching off the circuit breaker or unplugging the pump. This will prevent any accidental electrical shock.

Step 3: Check the Fuse or Circuit Breaker

If the water pump isn’t turning on at all, the problem may be a blown fuse or tripped circuit breaker. Check the fuse or circuit breaker to see if it needs to be replaced or reset.

Step 4: Inspect the Impeller

The impeller is the part of the pump that moves the water. If the impeller is damaged or clogged, it can cause the pump to fail. Inspect the impeller for any damage or debris and clean or replace it as needed.

Step 5: Check the Voltage

If the water pump is running but not pumping water, the problem may be a lack of voltage. Use a voltmeter to check the voltage at the pump and make sure it’s within the recommended range.

Step 6: Replace the Pump

If none of the above steps fix the problem, it may be necessary to replace the entire water pump. Be sure to purchase a new pump that is compatible with your system and follow the manufacturer’s instructions for installation.


  • Always wear safety gear such as gloves, safety glasses and hard hat when working on water pump.
  • Make sure to turn off the power to the pump before you begin working on it.
  • Never touch electrical parts with wet hands or while standing in water.
  • Always be aware of your surroundings and potential hazards.
  • Follow the manufacturer’s instructions when installing a new water pump.

By following these steps and taking the necessary precautions, you can fix a failed water pump and get your water flowing again. Remember, if you are unsure of what you are doing, consult with a professional.
