So, we've been struggling with a leak in our pool.
We've been loosing water almost as fast as we've been adding it. Of course the lack of rain and the hot, humid weather we've been suffering does not help the situation.
Have had the pool company that installed our new liner on-site several times but the crew (rookies) have been unsuccessful in determining room cause or locating. They did pressure test the lines, which all came back fine, and visually checked the entire liner, with focus on known areas that tend to give way first, and found nothing.
They did, however, mark the water line each time then came out with electrical tape, see above. All this did was give us a visual at the water loss. Like watching money go down the drain...
So, last week I ran a series of tests and in the end I determined that in the 48 hour testing period we lost 1" of water. Now keep in mind our pool measures 20'x40'. so 1" is a lot of water.
Much to our surprise the owner of the company stopped over this past Sunday evening and within 5 minutes identified where the leak was! He chalked this up to "years of experience".
It ended up being in the one location that was NOT touched with the installation of the new liner. It was the seal behind the water return jet coming out of the fiberglass stairs. The under side had simply worn away, which you couldn't see unless you were under water looking up. The good old, pool guy leak test proved out his theory - simply squirt this dye in and around the affected area and watch the dye get sucked into the hole and gone.
Sealed the entire area around this jet with a special underwater sealer and WA-LA, no more leak!
