Hello, all! Long-time reader, first post. I've attached a pic of my problem.
I opened the pool last week and stupidly walked away after starting the pump. When I came back about 14 hours later, I was met by the sight of water jetting out from between the multi-port valve and the filter body.
All works fine on waste/rinse/backwash/circulate. But when set to filter, it immediately acts like a very expensive sprinkler system!
Any ides/tips/dire warnings before I start taking things apart and randomly looking for clues?
Thanks in advance for any help.
