having some problems w our hayward filter, now at least 9 years old..
was leaking water through the bottom of the filter while it was running (through the cap at the base of the filter). I started to think that this was pressure related, but could not confirm this bc my gauge was broken. replaced the gauge. now h20 is leaking through the gauge (at has tape on it, but still leaking).
prior to replacing the gauge, i was not getting good pressure on backwashes (of course this is a visual sense of pressure since we didnt have a reading). when the filter was running normally, the pressure would seem to build up over about 30 seconds to normal pressure.
any and alll suggestions welcome. i am inclined to call in a pro but havent yet given up on fixing it myself.
