JTGgotta get a mask on and check all of the pool penetrations. I would let it fall to below the skimmer and then if not let it go to the returns. if you have a set of drains dye test them. with a leak that large you would be pulling water from the pool into one of the openings, you can see the dye slowly get sucked in to eyeballs, drains, etc. just takes patience. leave the pumps off and figure out how much water your losing with system off, you can find it with enough detective work. theres gotta be a wet area around the pool somewhere otherwise its getting sucked down beneath the floor
It is below the skimmer and I am manually draining it past the returns to speed up the process and will see if it drops overnight. No drains been dye testing and not seeing any movement of the dye. I have dug down to the light niche and I had backfilled with a little layer of clay around the nitche to protect it and that was really wet. I will see if there is any standing water around it since my bond beam will let the water pool. We have had a lot of rain over the last 4 days so that may be just the water settling. I am thinking it is getting sucked beneath the floor. One pool guy is coming out Thursday and another Saturday. I scheduled 2 since some don't show in our market.
