Losing suction during vacuuming; not because of air
Losing suction during vacuuming; not because of air
I have a 15k gallon inground concrete pool with a sand filter. Filter sand was refilled 2 years ago and has worked flawlessly since. I recplaced pump about 6 months ago and have had no trouble since. I am having a problem when vacuumming. I attach hose into my single skimmer inlet like always. I backwash prior to beginning to start with a clean slate. Filter runs around 15psi when beginning. Then within a couple minutes I am at double the psi or more and lose all suction. Not getting air in the line; pump basket not clogged; can't figure out problem. I backwash and all is well again, pressure drops back down and suction is solid for about 2-3 minutes again. Then, no suction, high pressure, plenty of frustration. Any suggests?

Perhaps the new pump is more powerful than the previous one and the restricted water flow through the vacuum hose is causing this problem.
Try a pressure relief valve at the skimmer or try opening the main drain suction line and see what happens.
