Broken Hayward valve SP-711

Thanks for the reply. So far I have cleaned the pool of all leaves and trash, the pump seems to be OK and pumps very well. For the present I am bypassing the heater, the filter seems to be working because when I first tried it out after emptying the pool the pressure from the jets dropped off pretty quick so I back-washed the filter and it worked great after that. My biggest problem now is leaking around the base of the valve, a really bad leak.

Sounds like you got lucky if the valve is the only problem. Only thing I can suggest is to pull the valve and see what happened. Could be as simple as a new gasket. There is a big O-ring that may need replacing. The clamp band has to be on pretty tight. I snug mine up every spring when I put it back after winter and of course it will leak, then keep tightening until the leak stops. But, I would check that O-ring first. If the body is cracked you should probably just get a new valve but trying to seal it from the inside with JB Weld may work too. Can't lose anything by trying.
