Why Is My Pool Pump So Loud?

From https://www.swimmingpoolsteve.com/pag... - Swimming pool pumps can get loud as they run for a number of reasons. Some of the noises you might hear are humming, whining, gurgling, or vibrating. A couple common reasons for pool pumps making loud noises are faulty bearings, motor vibrations and also motor speed. Vibrations from the running pump motor can be louder than expected, especially if that pump is sitting on concrete and / or close to a house. Setting the pump on a thick rubber mat is one solution for noise made by the motor vibrations. When bearings fail, you will more than likely hear a high-pitched metal squealing or whining sound that gets louder and louder with time. The bearings can be replaced as part of a motor rebuild or you could replace the pump. Single-speed run at only one speed - maximum or 3450 RPM. When the motor is running at high speeds like this, there will be increased noise from the motor itself along with increased noise from any vibrations cause by this high-speed motor. Having a variable speed pool pump installed on your pool instead of a single-speed pump can help reduce noise pollution caused by an old or failing pump. The variable speed motor allows you to turn the RPM down from maximum which decreases the motor noise substantially. Here are some videos on noise testing variable speed pool pumps:    • Variable Speed Pump Noise Test   - Variable Speed Pump Noise Test (Pentair)    • How Loud Is A Hayward Super Pump VS?   - How Loud Is A Hayward Super Pump VS?    • How Loud Are Variable Speed Pool Pumps?   - How Loud Are Variable Speed Pool Pumps? #SwimmingPoolSteve #poolpumps #variablespeedpump
