We noticed we were losing water a bit towards the end of last summer and it definitely got worse this summer.
It did not leak over the winter so I know it isn't in the concrete part or bottom of the pool.
We just did the bucket test and the first day it was a decent difference of about 1/2 inch in and out of the bucket. It does seem to slow down - over night the next night was barely any difference.
I found a crack in the grout of the tile by the skimmer and also noticed when cleaning the skimmer baskets a possible location for a leak? There is the one hole that gets plugged in the winter and then another thing that has a white cap on it. There is foam/rubber stuff under that cap between the cap and the bottom of the skimmer that seems lose and old.
I took these two pictures. Do you think it could be one of these things?
If so, are these easy fixes for us to do ourselves?
If not, is there any way for us to figure out where the leak is without calling a leak detection place for hundreds of dollars?
