I believe my Hayward Vari-Flow multiport valve ( Model number SP715XXR50) is the source of a leak which causes water to drain out of my DE filter and pump when it turns off. This just started today after I removed and completely cleaned my DE filter. After I turn off the pump you can air and a gurgling sound coming from the multiport valve and if i slightly depress the handle it gets worse.
I could try taking off the filter housing top and putting it back on to make sure there is no leak in filter but it sure sounds like it is coming from multiport valve.
I was aware not to rotate the valve while pump was running, but i've been reading here that i was always supposed to rotate handle in the same direction which i'm not sure that i have done, i think i rotate whichever way was the quickest to get to the setting i needed. I was unaware of that, and it's not written on the valve.
If i go ahead and add DE back into the filter, will it all fall off the next time the pump stops and water leaks out of filter. If so will it reapply itself to the grids next time it starts up, or will it just be all messed up internally?
Pool is not really open yet, i can leave it in recirculate mode until parts for valve arrive, its covered unless being used so the filter gets minimal use.
Thanks for you advice/thoughts!
