Hi there
I have a similar problem. I live in CT and I was having 1/2” to 3/4” water loss from my pool. Interestingly, when we opened it, it was quite full. We just bought this house with the pool and it is our first experience with the pool.
The loss could not be attributed to evaporation. The pool guys determined that I had a leak from return jets (the ones closer to surface) , which we fixed. The liner was also faded, so we changed it. After the pool was refilled, we notice at least 1” of water loss per day.
We have already pressure tested all the lines, including the new return jets, and they were all good.
The main drain pipe was not pressure tested. Instead, they cut the pipe open, plugged both ends at the deep end of the pool and filled the pipe with water. The pipe was holding water ok (just little loss which the guy felt was from evaporation, not sure if that is accurate )
It is so frustrating ! I am suspecting the leak could be from the site of the liner attachment to stairs, but I can see how the ink test could be useless !
I am also concerned about the main drains, but maybe a leak that is high up in the pipe.
By the way, it’s not necessary that your pool would be completely empty with main drain leaks.
Only leaks in the pipe part that is under the pool would lead to an empty pool. If the leak is in the part that is running upward, or the part that is closer to the pump, the water level will stop at the same level of the leak when the water pressure in the pool equalizes with the water pressure in the pipe.
Any updates on your pool situation ? Did you figure it out ?
