Easy to install Got a agreat deal on this water heater. Replaced a GE that only lasted 3 years. Like the new control box. No need to use a match to light pilot. Started up the first time I tried to lite it. May 27, 2014
Great features I liked my new water heater. It was thinner and tall and easy to install. Heated the water very fast. Very happy customer March 29, 2014
Works fine so far except for the drain valve. The design of the drain valve is terrible and there are no instructions on how to work it. The outer ring looks to be the thing to turn but isn't. There is no mention that this is a ball type valve and to be operated by using a screw driver. February 26, 2014
