I have recently just noticed that I had lost some water and it seems more than usual. I tying to figure out whats going by monitoring the water level and isolating each zone (i.e. skimmer, main drain etc..) trying to figure out if there is a leak and if so, where it maybe coming from. i just wanted some advice from you all on what's the best way to figure this out. I just bought my home and this is the first year that I'm running the pool. I noticed by the main drain there is what appears to drain with a stopper in it (similar to one in a bathtub). Not sure what this is, but I figure its a drain to empty the pool? Any idea what this may be?
What I was wondering if there would be any conclusive signs from the filtration system or chemical readings that may indicate a leak? I figured if there was a leak in any of the lines, the pressure in filter gauge would be low?? Or an indication in the levels of CYA or salt as it should be going down? Which in my case its not happening.
I'm going to dive down and check the stopper at the bottom to make sure its firmly secured? Any ideas or advice? I'm freaking out a bit as I imagine this would be a costly repair if there is a leak somewhere.
