: My washing machine discharge goes to pipes that run through or under the concrete floor of the main level of the house. This pipe connects into the discharge pipes in the basement. Somewhere between the machine and the basement there is a leak. Do you have any suggestions other than breaking up the concrete pad of the family room?Depending on the pipe size, there are companys around that can line the inside of the pipe without damaging the ground above.
