Signs Your Pool Pump Needs Repair or Replacement

August 30, 2017

The pump is the heart of the pool’s plumbing system. It creates the water flow that makes the chemicals circulate evenly throughout the pool and to the filter, chlorinator and heater. The pump increases the effectiveness of the pool chemicals that fight bacteria and algae in the water, keeping it sanitized and clean. Regular pool service San Diego CA or in another area you live will help your pool stay in optimal working shape.

To recognize when it’s time to call your trusted pool service experts, take a look at a few common signs that your pool pump needs replacement or repair.


Pool pump leaks are a serious problem because they can burn out the pool pump motor. They can be caused by a malfunctioning shaft seal, thread sealant, an impeller or the pipe that comes out of the pump.

If your motor shaft gets damaged, you may notice water on the floor around the pump. A leak in the pressure side of the pump will cause a drop in water pressure and a water loss. Water spraying from the pump housing is a sign the pump seal is broken.

To avoid that your pool pump become compromised, when you spot a leak, contact a company that provides pool service San Diego CA or another area near you.

Low water level

The pump’s impeller is responsible for pushing water through the plumbing system. So one of the reasons for a low water level is a clogged or worn pump’s impeller. The low water level can cause excess air in your pool pump and filter, and if the pump continues pushing air instead of water, it will soon overheat and burn out. Check out the impeller and if it’s clogged, clean out the debris to avoid this from happening.

Air Leaks

Small air leaks are quite common and harmless but when the air leak gets too large, it can interfere with the water circulation and cause the pump to lose its prime. An air leak is usually caused by a leaky valve stem on a suction valve, a break in the plumbing, or a damaged thread sealant.

Loud noise

A loud pump is definitely not something that you or your neighbors enjoy during leisure time. If your pump is making noise, you should listen to it to determine if the sound is coming from the motor or the wet end of the pump. If you hear a loud screech or grinding, your pump may need new bearings.

It could sound like there are small rocks in the pump. Vibrations along the base of the pump or cavitation may be the culprit. Cavitation happens when the pump can’t get sufficient water fast enough, causing the pump to run dry and lose its prime over time. Sometimes debris can get pulled into the pump, so you should also look for internal blockage and clear out any obstructions.


The pool pump can fail due to many reasons but before you start troubleshooting, first consider the age of the pump motor. Its average lifespan is approximately 7-10 years. If your pump is approaching this age, you may face frequent repairs and breakdowns. In this case, it’s better to buy a new one than wait till the cost of maintenance outweighs the value of the old pump.
