a leak on a pipe
You may have a suction leak somewhere between the pool and the pump. Or, you have let the water level drop below the middle of the skimmer(s). k
Leaves in the impeller of your pump.
pump was ok until I cleaned mess in pool. after that lost pressure. Changed sand but no luck
Yes its called voltage drop. The longer the extention cord the lower the volatage gets.. causing the motor to run at the wrong rpms causing a pressure drop.. long term will burn up the pump.
Air pressure is caused when you pump it with an bike pump!!!!!!!!
When the pressure on your pump goes up
The pressure increasing indicates that something is blocking the filter.
So long as there is water coming through the pump when it is running it doesnt matter what the water level in the pool is.
Probably below 5#'s ???
