My in-ground pool is configured with an auto fill valve. When we first moved into the house, it was running constantly. I have turned it off until I have a chance to replace the shut-off mechanism.
However, when messing around with the auto fill, I noticed that the overflow is below the ideal water level (or at least how I perceive it) for the skimmer. Meaning, if the water level rests below the overflow, the water level is about 2 inches below the hard water ring around the below, and is just barely above the bottom lip of the skimmer cavity.
I also might mention that there was a wine cork shoved in the overflow drain, though I don't think it was making a good seal based on how quickly the water would drain.
Any ideas? What is the proper water level relative to the skimmer? Is plugging the overflow acceptable? If so, is there a better solution than a wine cork?
Thanks in advance!
