Thread: Sand Filter ORing Leak

    Sand Filter ORing Leak

    I have replaced the big oring on my hayward s 200 twice in the last year and it will not stop leaking around the oring. I have taken filter apart and checked oring for crimps or debris and find nothing. Anyone have any suggestions ?? Pool store has not been any help at all.

    Have you used a suitable o-rin lubricant? Something silicone based is best. Also, check for nicks and cuts in the o-ring and make sure the o-ring and both sides it mates to are free of debris.

    Yes I used the lube from the pool store. It is a brand new oring I just purchased it and put it on. the leak is not isolated either it leaks pretty much around the whole oring. I even tried different levels of tightening on the bolts. Hand tight, snug and just kept making the bolts tighter and tighter but nothing helped. Someone help ????

    Is it possible to put too much lubricant on the oring and possibly create leaking ? I put quite a bit on it to attempt to stop leaking.

    Too much lube would just squeeze out and the ring would seal. Have you checked the bosses where the o-ring lays for debris and defects?

    Welcome to TFP!!

    Ditto to what Bama said.

    Also, are you tightening the bolts properly? (the proper way is to put all the bolts on ~ hand snug and then tighten them in pairs N&S, then E&W, then NE&SW and then NW&SE. That will put even pressure on the gasket and then you can just tighten the rest of the bolts.

    Yes I am tightening the bolts properly. I have also taken the bolts out, cleaned and checked for any problems bur cant find any problems. I put it back together and it starts leaking again. I dont get it. It just constantly drips in differnt places all the way around the bottom of the oring seal....

    New o-rings, lube and properly tightening the bolts... Is there any chance the body, top or bottom is cracked?

    Re: Sand Filter ORing Leak

    Okay I went out and really tightened bolts tight as possible. It helped some but it still drips in 2 spots on the right side which are about 3-5 bolts from each other.
