First post in the forum, but I have been lurking for a while. I just diagnosed and fixed my salt water chlorinator by soldering a new rush current limiter to the board, thanks to helpful posters here.
So, to the current issue. I have water leaking at a pretty good rate. It is not evaporation. It leaks when the pump is on, but does not at all when the pump is off. It stops at the level of the skimmers, but I think that is because the pump cannot get any water at that point to force it through the return lines which I believe to be the source of the leak. First off, could it be anything other than a return line. Second, is there any way that I can test the return lines.
A little info. I cannot dig to any point around my pool. The concrete on both sides where I have returns and skimmers goes up to retaining walls. One wall is above the pool grade and the other is below. I believe the concrete will have to come up to fix this issue. Also, the leak happened or became significantly worse about 1 week ago. I now have to add about 3 inches of water a day to keep up. Before a week ago, I added water every 2 weeks or so.
Thanks in advance for taking a look
