Glenn from Christian Brothers was great. He asked a lot of questions about our plumbing before performing the service, which we knew was going to be hydro jetting the kitchen sink. We had someone else out twice to to snake it, but it did not resolve the problem. He ended up running the hose down line from the roof. As he jetted the line, the sink filled up half way with dark dirty water stuff that had built up in the pipes. Shortly after that he obviously cleared the blockage because the water drained very quickly. It's not an inexpensive service, but it was well worth it for us. This was about a month ago and we still have not had any problems with the sink backing up.
