Sorry, I'm posting this twice but this feels more like an emergency and someone might not see it soon in my laddy-da empty our pool post. We r just filling up our pool after emptying it. husband turned on the filter for the first time after refilling the pool and i heard water spraying-gushing-lots of water spraying everywhere near the pump. we ran over and it looked like it was blowing out of the panel but what it looks like we did was after backwashing and tearing down the DE filter we did not put the handle in the position so that the water would go back into the pool because we weren't going to finish the process of adding DE and all of that as we were going to empty the pool. My husand said he saw water squirting out of the top of the DE filter where u r supposed to release pressure and the whole top part of the DE cover spun at least 90 degrees. water was spraying everywhere, into the panel it looks like. I imagine the panel is on GFI but it all happened so fast and all I was thinking was how water and electric don't mix but we had to shut that panel off. We did shut it off and it was still running for a while but i guess that's cuz there was water still coming out of the blue hose that was folded away and now blowing out from everywhere it could. Now do I open the panel to try to air it out? do i call the pb? help! thx!
