Can anyone tell me why the pool water level drops when I set my vari-flow valve to filter and it sends the water out to my drain? I have to keep a hose running into my pool because if not the level drops so low that the skimmer can't function.
A pool guy told me I needed to change out my sand filter, which i have done, and it continues to do it. I want the water to be filtered by my sand filter, but instead it goes down my sewer drain.
Any help is appreciated!
