just bought a house with a pool. the filter pressure runs at about 22 PSI right after a backwash is this abnormally high?
my equipment is
hayward RS1500 pump with ratings of 1.5HP, 1.33 SF, 2 THP
tagelus 60D sand filter
1.5" plumbing everywhere
2 returns (i noticed some fresh plaster spots at the same height as the other returns, guessing there use to be more returns)
And for what it is worth I dont feel like it filters that well, I seem to always get a poof of something out of the returns when i start up the pump. I had to drain and fill about 75% to get my CYA down and am currently slamming. i am passing everything but the clear water criteria to stop the slam.... test results below
PH=7.4 (measured before starting SLAM)
some other factors that may be of importance,
i have been doing the add some DE to your sand filter trick.
I rinsed the sand once by removing the top valve and running the hose down in the sand, water started running clear but not 100% sure I got it perfect, its difficult to get a hose and broom handle down in the top of that filter trying to break up chunks and watch out for the laterals all at the same time.
If I run the polaris and it gets really cloudy (stirs up dust), about 2 days later with polaris out of the pool dust will settle on the bottom. if i try to vacuum to filter the pressure spikes then plumes of dust come out of the returns and the pressure drops back down.
so anyway my thought was the pressure was too high which forced this dust **** all the way through the filter and back into the pool, my next step was to change out the sand. but am really just playing guess and check at this point so figured i would ask here..
