I've been having trouble with the in-line filter clogging severely everyday. When clogged, the pool sweep will not operate and the sand filter pressure gauge jumps up about 10 PSI. This morning I cleaned the in-line filter and once I turned the pump on, tons of water pressure came shooting out of the pressure relief valve by the quick disconnect on the hose and the pool sweep was running like crazy (I wasn't sure if this was good for the system?). The sand filter gauge dropped 10 PSI after I cleared the polaris filter. Can anyone help as to why my polaris in-line filter is getting clogged so severely and so often? I'm a newbie so I'm not sure how the water is filtered before it goes to the pool sweep hose. (BTW we do not have a booster pump).
