It's a bit long, but I really need to find a quick answer.
At home with pool and moved obsolete equipment. We filled the bottom of the bath attatched with sand, gravel and cement, it is now a body of water for small children. Plastering boy said he did a good job and then get to work. To save money on labor, the husband of the label and cut the pipe and equipment (about 1.5 meters above the ground) when everything was for the type of sanitary-) pool clean (various co-plaster. In order for our new team. After asking me once, and even a kind of plaster on the pressure test of our pipeline, says it is not necessary. After the re-plastering and filling the pool Saturday evening has the pump and filter 1 minutes under water in a large pop and spa center cracked when filled Discover explored the nature of the filter and pump return l ', so that the cursor moves to water, not to .. forcing the air / water drain in the spa break, so that the cement. Cried the man, he comes to fix the pipes, but caused no excuseSaid my husband had checked the pipe and that's what happened ... So basically our fault. If it is not pressure tested pipes or drains can to ensure that the tubes cause this? I talked about our spa and said only: "Oh, that's not good."
May I say that his guilt was the place cracked and need to take responsibility?
