I havd a leak in the spa, after the pump for the pool and spa goes off the water level in the spa drops about 1 inch over night. I check and replace the valve thinking that was the problem but it isn't. A pump service guy came and used the dye detection and said it looks like it is leaking at the light. So I drained the spa into the pool and usede the pool putty where I think it could be leaking such as around the light cord inlet and everywhere else. Waited until it was dried and put water back into the spa. The following day it leaked half the previous amount about 1/4 inch bellow the water line. Is it possible to use flex seal and just spray the area and see it that takes care of the problem and will that hold. I am gettin frustrated now.
Thanks
