Since opening the pool this year ive noticed lower suction when vacuuming and my pump isnt fullt priming. I just got the pump installed last year and ive gone though trouble shooting and i couldnt find any leaks. I tried running the pool without the filter and that seemed to be the only way to get it to fully prime and get serious flow out of the pool jets. The filters atleast 3 years old. Could the filter be the actual issue causing the poor flow and priming, or is this a somewhat imaginary solution?
