I'm losing about two inches of water every day in a 20k underground pool. I've hired a leak specialist company and they outlined an area to dig. I've hired a separate company for that work. I'm attaching a picture. They stopped digging since they didn't see any moisture and therefore don't believe the leak is in this area. I'd like them to keep digging until they get to the pipes but they stopped to not break the pool's deck. The top part of the picture is the in-floor cleaning system. The bottom of the pic is a rock waterfall fixture. There are two returns/suction lines on the sidewall, three feet deep, which would be on the left side of the hole in the picture.
Any other recommendations? Should they keep digging at an angle in order to not break the pool's concrete deck?
