My rental water heater decided to not heat our water past luke warm one day and so I knew we had a rental water heater so a service call should be free, and it was. A gentleman came by to look at it and showed me what was wrong and what needed to be done which was nice of him. He said the mixing vale needed to be replaced and that it would be around $100 for a new valve. A was on the fence about it because I thought maybe I could get it at a plumbing supply store for cheaper so I said I would call D.E if I wanted the part. Not a day later a package shows up at my door and it's the new valve! The gentleman dropped it off free of charge, as a student I was so happy. We need more people like this in the world. Not sure if I should call to thank him because he might get in trouble or what. Anyways, absolutely superb service!
