Conscientious Plumbers - Roto-Rooter.
I have used Roto Rooter twice already this year. The first time to install a new kitchen faucet and they came in January during a snowstorm - did a wonderful job and I have had no problems. This November I had a leak under the kitchen sink and I thought it might be the dishwasher but it turned out to be one of the large pipes had a tiny hole in it which was getting bigger. The plumber found it within 30 seconds and replaced the pipe piece right then and there. He got the part cut it down to fit with a special tool he carried with him and within 15 to 20 mins he had fixed the problem. He also gave me advice on how to keep the drain clean and a gallon of the Roto Rooter pipe shield. I finally found an honest plumber with a good attitude. Thank you Roto-Rooter!
