What can cause a pool pump to lose prime?
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.
What does it mean when your pool filter pressure is low?
Filter Pressure Is Too Low. Low pressure in your filter is much less dangerous than high pressure, but it means your filter isn’t doing its job. Low pressure will (almost) always be caused by a problem at or before the pump. That’s because after the pump the water is under pressure so any problems would produce high pressure, not low.
Why does my pool pressure keep going up and down?
If flow rate changes, pressure has to change either higher or lower. Lower pressure would mean a suction side problem or a clogged impeller. Higher pressure than normal would indicate a filter problem. If you just opened the pool, the problem could be an algae bloom which is quickly clogging the filter.
Why does my water filter pressure go down?
After cleaning the filter or backwashing it the filter pressure should drop. If it goes back up within a day or week there could be a few reasons for this. One, the grids or cartridges are worn out and need to be replaced. If you have a Sand Filter the sand could be really dirty and you will need to clean it or replace it.
Why does my filter have a high psi?
A filter pressure gauge is used to measure a filter’s PSI and every filter should be equipped with one. The most obvious reason for high PSI is that the filter is dirty. Simply cleaning the filter or backwashing it if you have a D.E.

Why is my pool pump pressure gauge low?
Check the skimmers, pump basket, pump impeller, and the drain covers for any debris that could be blocking circulation. The less common and more serious cause for a low pool filter pressure gauge reading is a leak somewhere in the system, most likely the pool pump. Examine the pump carefully for any indications of a leak.
Why is the water pressure in my pool so high?
A suction air leak before or at the pump is causing an air pocket inside the filter, which in turn creates the dreaded backpressure. Excessive plumbing creates backpressure as the water’s momentum gets slowed by every turn or rise in elevation it makes. Clean your Filter. The most common cause of high pressure in a pool is a dirty filter.
Why does the pool pump pressure go up after the impeller?
It’s never a problem after the pool pump, because after the impeller, the pool water is under pressure, and obstructions result in higher than normal pressure. It bears repeating: when pool pressure gauge reading is low, look for the problem at the pump or before the pump.
