I have a spa that sits above our pool and spills over into it. I just had a leak detection company tell me that 3 of the six spa return housings in the spa are cracked and that is where I am losing water. They are telling me that in order to replace these cracked housing that a section of my deck will need to be taken out and the spa housings ground out of the spa wall. We just had the pool/spa resurfaced two years ago for $20,000 😞 Is it possible to epoxy the inside of the existing housings to repair the leaks? Any and all advice would be greatly appreciated. Have a wonderful day.
