I closed the pool last fall & saw the water level drop steadily to about a foot below the return inlet. Since the water had leaked below all of the plumbing components I assumed the leak was in the liner. I already had the pool covered for Winter & the snow was flying. I was afraid that my leak may have been on the bottom of the pool and I didn't want all of the water to drain and have to pool collapse. So I refilled pool to just below skimmer level hoping that it would freeze and get me through the Winter. It did. Now that Spring has come the water level finally established itself at about a foot below the return inlet & has remained there for the last two months. I'm guessing that my leak is somewhere around this depth in the pool but I'm not sure how to find it (27' Round Pool). I'm ready to remove the Winter cover but wondering what to do next. Any Suggestions?
