Low Swimming Pool filter PSI
If you have low pool filter pressure, several things may also cause this. The most common reason is some debris is stuck in the pool impeller, restricting it and causing the pump to pull less water. Like a worn pump lid o-ring, a suction leak will also cause low filter pressure. A problem with the pump's diffuser can also cause this. However, a clogged impeller is the #1 cause and is easy to fix. Turn off the pump, remove the lid and basket, and then spin the impeller with a flathead screwdriver. This usually dislodges the debris, and you will then hear a gurgling sound as the debris is cleared from the impeller. Some apparent causes are a clogged pool pump basket, a clogged skimmer basket, and low water in the pool. Too much suction at the side port towards a suction side cleaner can cause lower pool filter pressure. A clogged inlet line can also cause low filter pressure. The filter pressure PSI will also read low if a variable speed pump runs at or below 1600 RPM. A clogge
