Question about Hayward EC75 HAYWARD PERFLEX FILTER SYSTEM W/1HP PUMP
To whom it may concern:
I replaced the sand in filter put a new 1.5" vari flo control valve in backwashed etc.. for start up. the dome of sand filter is now sitting on the 2nd story of my neighbors house other parts distroyed. i purchased new parts and it happened again. this happened on FILTER, on backwash and rinse excessive amounts of water leaking out of dome. I installed new O ring still doing it. any ideas?
IF your filter is really the EC75 that's listed in the heading, then it's not a sand filter, its a DE filter. See link to manual:
If this is not the correct number, then you can find the correct manual on their web site. So did it have a multi-port valve already? or did you install it. IF it is a sand filter then there is something plugged inside the filter (small fingers on spider?) If that's the case locate the manual on their web site and follow the assembly insturcitons.
