Since my pool was opened I keep getting a little air coming up from the spa jets, my handy valve is set to return about 80% pool and 20% spa (it has been set like that and cannot be manually adjust to pool only). The pool jets have good force and I do not see any air coming from there but the spa jets always let out a few bubbles. Also after the filter has been off for some hours it loses all of its prime and the basket is completely empty, then it takes about a minute to prime by itself.
Side issue and maybe I should post this elsewhere but my filter doesn't go up in pressure at all, just stays at 10psi. If I backwash it goes to 8 and then after DE it goes up to 10 but never higher...I took apart the filter and cleaned and everything seems to be good inside but still no change.
