Home Depot did not have the part we needed. In fact, some of the plumbing was glued together and we'd have to replace a lot more of the pipe than we had originally thought. The job could possibly include some cutting of the pipe as well.
They had to completely rebuild the plumbing system under the sink. Freddy G said there was only a little leak now, but if we put a towel down, we would never notice it!! HA HA I think they did a great job and the price was reasonable, too.
