FAQs – My Pump Sounds Noisier than Usual
Q: My pump sounds noisier than usual. What is causing this?
A: Motor noise – the front bearings may need replacing. Perhaps water got into them, which will ruin them in a short period of time. The bearings can be replaced but often the motor is replaced as a whole.
Clogs – If the water flow is restricted with clogged intake and the basket is full it will be much louder than normal. If something is clogged in the impellor this will be noisy too.
No Water – If a pump is starved of water it will tend to cogitate. This makes a lot of noise because the pump is working against itself.
