I've been cautiously adding water to my new DIY inground vinyl pool. Water level is still 12" below the skimmer and returns (which have not been gasketed/cut-out yet). Last night (cool night here in Texas about 45degF) the pool lost about 1/4" of water. I'm no expert but I believe there's a leak. A bit frustrating after all this work! Only options for location are: gaskets around steps, wet niche or drains. My main concern is that I damaged something during backfill.
Ideas on where to start?
