Vitals: 16x32 in ground, 1/2 hp superpump, older Sta-Rite filter, psi at baseline 12, no chlorinator, have been following BBB method for 12 of my 13 years here in AL. Four hrs sunlight, keep CYA around 40. As always, clear sparkling pool. Opened 10 days ago after extensive work.
Filter base feet began cracking over the years. This spring leaning so much intake and discharge pvc's leaking. Ordered a new one and nonpool but brilliant guy friend mounted and leveled filter on new stand. 13 yrs no sand change so added 300 #'s of silica pool filter sand. Added water first and as added sand made sure inside baffle pipe was perfectly centered (measured it along the way). He glued the white plastic moon-shaped thing onto valve head/multiport. Redid intake and discharge pipes using two couplings on each which had become quite butchered pvc over the years. There are no water leaks anywhere, not a one, however cannot get full prime. Plenty of water for pump, plenty of suction on my manual vac, just like always. But bubbles at top of pump basket (pump is only one season old, no issues); air bubbles constantly coming out of shallow end jet (no main drain on my pool); and obnoxious water-chortling sound constantly coming from multiport (should not have any noise other than hum of pump). Following directions I backwashed and rinsed a couple times. As expected lost a little sand out of waste hose, have none in pool. Since there are no water leaks we're stymied where the source of an air leak could be. He has taken multiport off several times to reinspect. Seal on pump basket good. New o-rings on the 4 new pvc couplings. Everything is level and tight. Put some dye in skimmer and see no leaks. Once upon a time it had a nonfunctioning main drain, had new liner guy 6 yrs do away with it so that 2nd port in skimmer is always closed.
Any ideas? We are plumb out of any! Thanks a lot.
