We have a recently installed inground pool with a Pool Miser autofill/overflow. The overflow drain is connected to our subsurface drainage underneath the travertine decking. The exit point for our subsurface drainage is out by the street by the curb. My issue/question is that the exit point keeps having water drain from it all day long. We haven’t had significant rain lately, so it’s got to be coming from the pool overflow. This has gone on all day today. When I open up the top of the Pool Miser, I see water draining into the pipe. What could the problem be? Why does the pool overflow keep draining all day long?
