Over two weeks in to June and we can't swim because of a leak in the pool. I can't seem to attach a photo but it has leaked below the skimmer, returns, and light niches over the past 7-10 days. The water level has remained mostly stable over the past week at about 18" below the top of the pool. Besides a leak in the shell itself (which I can't see), the only thing left is my main drain and/or plumbing from it to the filter.
While 18" isn't too deep of a hole to dig, can anyone give me some input on other possible ways to detect the leak, without calling a leak expert? At this point I can only assume the leak is in the plumbing (flex tubing, I think) from the main drain. I'll dig a long hole to find the leak in the tubing as long as it's less than two feet deep
