We are new to this forum and new to pool ownership completely so I apologize in advance for probably sounding stupid and not using the correct terms! We have a 24 ft/54 in round above ground pool with a 1HP pentair pump and black diamond cartridge filter (we also have a leap frog chlorinator and pentane heater).
Our pump and filter were running wonderfully for the first 3 weeks of use. The gauge was running at about 13 PSI With great water pressure coming out of the return to the pool. All of a sudden this weekend (only week 4 of a brand new pool) we noticed a very week water pressure out of the return and saw that the PSI was up to 18-20 (which is where the "clean filter" indicator is). It seems crazy that things would already be so dirty but we've tried everything to clean our brand new equipment! Cleared all the water, hosed the filter and cartridge, cleaned the skimmer out, cleaned the pump basket out. We vaccuumed and cleaned all the walls. Nothing is working! It's got such a weak pressure now into the pool from the return. Is this normal? Is this just now it runs normally now that it's a month old? One noticeable difference is the pump basket is just full of water while running where before we could see the water swishing around.
Any suggestions would be greatly appreciated!!!
