He changed out our water heater. He also put in a hot water line in my attic, diverting a line that had gotten a hole in it.
It has been a very bad experience. I, stupidly, trusted him. After talking to a trusted plumber, he charged me double what he should have. In putting the line in the attic, he tried to charge me $1200 for 2 1/2 hours of work. I told him he was crazy. He caused a real scene and had a deal with a cop that was working with him. I was able to cancel the check and paid the plumber a reasonable rate. He has a reputation amongst those in the area.
