On Friday my hot water tank blew. My local plumber came out and said even though it was a 6 year model it was broke due to "goop" lining the bottom of the tank. He sold me the above model for 645 with installation. In situations like this how does one determine what a reasonable cost is for installation. He said the tank was 345 and the the remaining was for labor.
Don't get me wrong I'm not saying I was cheated, but I felt pretty helpless in making this decision since I had no information available to me to make an informed choice.
