So our pool saga continues. In the last week the pool has been dropping a lot overnight. I thought it might be the sealant around the skimmer so we let the water drop below the skimmer but unfortunately it's still dropping. We did the bucket trick last night at about 4pm and when I checked this morning at about 11am the pool had dropped by just under 3 cm (1.1 inches) and the bucket water has barely changed.
What's the best thing to try next? I have no idea how to block the drain - I don't even know if it's in use.
We put a light back last week (it doesn't work but it was better than having a wire hanging out of the pool) and wonder if we might have torn the liner. I did a quick dye test near the light and return jets and it doesn't seem to be sucking in water.
We have a vinyl pool so I'm aware that we can't let the water drop too low. How low can we go?
Thanks for any advice.
