Just finished building the pool and I have verified that I have a leak. Bucket test etc. I am about 95% sure it's in the returns in my plumbing (six returns). When the pump is running and the returns are the only outlet are on I get about 1" of loss every 24hours. This translates to about 500 Gal. With the pump off I lose about half of an inch.
There are muliple points around my pool where the water is showing up on the surface. It's an inground, vinyl pool about 30,000 gal. The pool builder mentioned something that if it was a small leak just putting a couple of quarts of "fix a leak" in there. This doesn't sound like the greatest solution to me. I'm going to guess this group feels the same way, however if you all thought it to be okay I might just go ahead and let him do it to prevent digging up, and potentially busting out concrete.
I called a American Leak detection and cost will be about $500. I offered to split this with the builder and he agreed if I wanted to go this route although he said he could do the same thing they do.
Looking for feedback as to what the best route is. Right now I already have vermiculatie that will need to be repaired because some of it washed away when the liner floated due to the leak. And the builder has agreed to fix
