New pool owner here. I'm questioning my filter pressure and wondering if it seems "normal". I understand there are probably a lot of factors that determine "normal" pressure. I have a brand new above-ground pool 24' x 52" with 1 skimmer and a main drain (normal 2 8" round drains about 5' apart in the bottom center). Plumbing is run with the normal bundled 1 1/2" flexline (main drain uses 1 1/2 flexible PVC). I forgot to grab the model name / number off the pump & filter, but it appears I have these (browsing Hayward's website):
Filter: Hayward Sand Filter - Pro Series Top Mount
Pump: Hayward Power-Flo LX (I remember mine was labeled 60 GPM & 1HP)
Ever since the initial install my filter pressure gauge reads 11psi when clean (ie. when initially setup & immediately after a backwash). By the time it reaches 13psi the flow out of the return seems greatly reduced and so I backwash (this ends up about every 2 or 3 weeks I guess). When I switch between main drain only or skimmer only the pressure remains about the same; I think on main drain only it might drop to about 10.5psi. The water circulation appears to be very good (when filter is clean, running 11psi); I can see the whirlpool effect.
Does this sound normal? I read of others with much much higher pressure readings.
P.S. I've added my first jug of good ol' bleach this past week! I'm on my way to converting to the BBB!
