I've only owned this house 4 years. My pool was originally outdoors. It is between 20 and 30 years old. Our house was built around it and it became "indoor" except the area isn't heated, it's just enclosed. It is a vinyl lined pool and it appears there is a single main drain, a skimmer, and 3 outlets. There is a 1 speed motor, cartridge style filter, and a old heater that is simply either on or off. No thermostat. I estimate the pool is about 20,000 gallons. The equipment room has a crawl space hole in the floor to access some of the plumbing that runs the long side of the rectangular pool.
Several weeks ago I noticed the level was getting low so I added water. I forgot about it so it overflowed. (Not the first time I've done that). Afterwards the water level began to drop drastically. Like a foot in a day. I had a line leak once but that patch was still holding. I figured I would let it drain until it got below the leak. In hindsight maybe not a good idea. It has now lost more than 3/4 of the water. I have no idea where it all goes except into the ground. We live very close to the Great Salt Lake and our water table is very high. This leak could be pluming and not the liner but I don't see any water in the crawl space. The liner was poorly installed. I think it's too small. The stairs have a bunch that has pulled away like it needs stretched to fit correctly.
Where could this leak be? Any ideas how to search for it with the little remaining water?
