For the past two or three years I've been losing more and more water from my pool each season. This summer my water bill was astronomical. I found a crack in my skimmer which I patched using A+B epoxy putty but I think the real problem is that my drain line is leaking. The water level has dropped to a few inches below the returns and has remained stable. I don't have a light niche and I don't see any source of a leak in the liner. I am thinking I should drain the pool, plug the drain, and pressure test the drain line. If the drain line fails I guess I'll have to pay for leak detection and be prepared to dig out and repair the pipe.
My questions are:
1. What is the easiest and most cost effective way to pressure test the drain line, or any other line, myself. Please include details or a link to detailed instructions (Unfortunately, I don't have a way to remove the drain cover and plug it without draining the pool as I'm too buoyant, can't hold my breath long enough, and I'm not scuba certified.)
2. If the line is leaking is there a way to pinpoint the location of the leak myself or do I have to use a leak detection service?
3. Has anybody on the forum has done this before?
if you live in the Atlanta, GA area and are willing to help me fix this for a reasonable fee feel free to PM me. I'm pretty handy and I want to keep the cost low by doing as much of this myself as possible.
