Hey everyone found the forums and have been trying to understand how everything works, bought my first house and it came with an in ground pool. The filter is a Hayward DE EC65. My understanding is, you watch the pressure gauge and when it goes above 10 psi over the original starting point turn it off and bump it. I've done this a few times and recharged the filter after dumping the DE out. Now, how long with a relatively clean pool can you go without having to bump it? It seems like my pressure reading shoots up over 10psi after an hour and a half or so. Is this a sign of a bad filter? Or should I try disassembling everything first and cleaning it out?
TL;DR How long can you go without bumping the filter on a clean pool. Mine only lasts 1.5 hours.
