I called Arnold & Sons Plumbing, Sewer & Drain to come out and find out why the washing machine was backing up into the shower. The plumber arrived on time and was very courteous, applying plastic on the floor to keep it clean. He did get the back up into the shower slowed down by augering out the line, but it did not fix the issue This plumber and also their receptionist was all professional in manner and I have no complaints at all about that. The only concern that I had was the cost of this service. It cost $300 just for a service call. I have spoken to them about the problem not being resolved and they are willing to come back out but if it turned out to be a different issue then it could cost me more than I am willing to pay at this time. I am still giving this some thought.
