Almost immediately after construction my pool developed a leak. Pool builder bailed on me but I had someone come out and they found the leak around the edge of the drain where the plaster meets the plastic - there was a small gap. He fixed it using the 2 part epoxy. That lasted about 9 months and then it began leaking again. I went down, cleaned out the old epoxy and added new epoxy. That lasted about a year, and then I repeated the process. That was about 12-15 months ago, and now it is leaking again. Probably, it leaks from the start and just gets worse and worse until I notice.
Anyway, is there something I'm missing? Is it normal for the epoxy to fail so quickly?
