Broken Pipes
Hello all I have a question about 2 broken pipes. I have been losing a lot of water out of both my IG pool and attached IG spa. Yesterday I had a leak detection company come out and he tested everything. I am losing water out of 2 broken pipes, one for the spa and one for the pool. Both pipes are returns. He plugged all my returns and my pool and spa hold water fine.
I have expansive soil. The leak guy said he has seen this in my area before. The soil gets wet expand and since I have a concrete deck the pressure is put on the pipes and breaks them.
My question is now I need to saw cut my concrete deck and dig down to the pipes to fix them. Can I fill the trench with sand? Will that help cushion my pipes against soil movements? Anyone else have an experience like this? Any other suggestions? Thanks.
