I live in west Houston and was having to add 2 inches of water every other day, got a TFP recommendation to try American Leak Detection Houston. Contacted them and setup a appointment, they showed up on time and made a thorough check on all of the lines and found 2 leaks, one in the skimmer wher the grout was missing and another in one of the return lined. I would highly recommend these guys. They also do repairs so I’ll be posting on that later.
