first time post - regarding a sta-rite swimquip 2" wc212-134p backflow valve.
getting pool ready for summer and now have a decent leak coming from the top where the piston come throught the top of valve hosuing and joins the handle. i disassembled and took a look, o rings look ok,
i cleaned off the piston but leak is still flowing.
is this a problem new o-rings should take care of ? the valve is older - is it worth simply replacing the whole unit?
any help is appreciated.
