A pool pump functions by rotating a turbine referred to as an impeller, which draws water across the pump and leads to the filter. Inside the filter, water is cleaned and sent back into the yard, pool or pond courtesy of the pump's pressure. Generally, pool pumps operate silently; however, a range of problems may lead to a noisy pool pump. Issues such as debris being trapped in the impeller, a jammed pump basket and air locked within the pool filtration system all make the pump work extra hard and generate more sound. The following are simple tips which homeowners can use to troubleshoot a noisy pool pump before actually calling a professional technician.
Shut off water supply to the pool pump. Detach the plastic pump lid and take out both the pump basket as well as the skimmer basket. The presence of debris inside these two baskets will cause the pump motor to work a lot harder to draw water from the pool and propel it across the filter. An overworked motor often generates loud sounds. With this is mind, use a water hose to spray both the pump basket and the skimmer basket to clear off any trash. Maintaining cleanliness inside the basket areas will ease pump motor clatter.
The next step involves scrutinizing the pump impeller. To begin with, unfasten the pump basket lid. Take out the pump basket and thrust your fingers all the way down the tube, which leads to the impeller. Try to feel the inside of the impeller to determine whether it's congested with trash and dust or if it's shaky or unsteady. Excessive debris or a shaky impeller is a major cause of a loud pool pump. Get rid of the debris using a water hosepipe. In the case of a wobbling impeller, the best solution may be repairs by a professional technician or replacement.
The third step is to increase the water level in the pool or pond. When the water level is lower than the mid elevation of the skimmer face plate, there's a possibility that air is finding its way inside the pool filtration system. Once air penetrates the pump, it interrupts the vacuum setting of the pump needed to sieve the water. Consequently, additional strain is exerted on the pool pump leading to deafening sounds. By running water until it brims over the pump, air that is trapped inside the pump lines is flushed out.
