Hello noob here again..
I'm thinking that I need to backwash my sand filter. For how long should I run it in the backwash and rinse positions? I can see little things swirling in the sight glass..does it have to be 100% clear before switching to rinse or how exactly should I do this?
My pressure is currently about 25 when in filter mode, and when I ran it in backwash mode it was about 10 if that means anything.
I'm getting a lot of bubbles in the pump basket, and I've checked/lubed/reseated the o-ring several times. If I try to use the zodiac barracuda vacuum it makes bubbles like crazy even though I can see no leaking of air at the vac end, I've checked all the hoses, filled it with water first before starting. If I adjust the jandy valve I can reduce it some, but then the vacuuming is not very effective. Could this be a problem with the zodiac itself? It seems to be cycling/ker-chunking and shaking then it starts moving around and then the bubbles come.
