Hi! I'm a fist time pool owner and a pretty savvy DIYer but this has got me stumped:
We drained our pool in order to paint it. Acid washed, TSP'd and epoxy'd a couple of hairline cracks. For some reason the main drain keeps filling with water and creating a puddle in the deep end. Slowly, but surely. The main drain has a hydrostatic valve and an open pipe that seems to connect to the second hole in the skimmer basket. We have not un-winterized, we used a sump pump to drain.
I need the pool dry so I can paint.
