Just starting up my pool. The suction is eratic on my Intex Sand Filter/Pump. Its as if the suction can't keep up with the discharge and the clear lid on the pre-filter is popping up and down (is it made to do that?). I've disconntected the suction to make sure it was clear and also backwashed to make sure there was not air in it. Also changed out the valve on the discharge side. Discharge is constantly surging...Any ideas?? I didn't have this problem last year...
