Good water heater. This water heater was easy to install. Easy to get it started heating. Price was comparable to similar 40 gal water heaters at other stores. April 17, 2014
good product bought this heater because the one I was replacing was the same only 10 1/2 years older. Happy with product April 14, 2014
Great Product Very easy to install and easy setup. Fair price too. April 12, 2014
Great Product, but Tank Leaks within 26 months every time. These water heaters never make it past 28 months without the tank failing. I know our water is bad out here, but I always install a "full-flow" ball-valve in the drain position of the tanks to facilitate removal of lime, which I do periodically. I spend over $100 in parts every time I have to change one of these out. We have two water heaters--both Whirlpool. They never survive the warranty period. Otherwise, they work perfectly. I just wish there was some way to make them last a little longer. Note: I owned a Car Wash for 25 years, where we had to perform plumbing on a daily basis. Although not a professional plumber, I can and have done all of the work on my own home forever. I am a perfusionist by profession. We operate heart-lung machines for patients undergoing heart surgery. Sort of the ultimate plumbing......Thanks for your time, if you are still reading. ;) April 11, 2014
Product had great review in Consumers Report So far its as advertised, good value for the money. Its quiet and looks great in the garage area were its installed. Installation only took the plumber and hour. April 9, 2014
I like the look We like the way it looks. The blue color is pretty. Easy to install. I like the height of it. April 6, 2014
for the price i think its as good as u can buy.. its a six year heater so thats about what u can expect just replaced this with one like it. think it lasted about seven years and this is a six year heater and never had any problems so I bought another. for the price to me its as good as any u can buy. I think its as reliable as u can get. April 6, 2014
Easy to self-install I pulled the old water heater out, and put my new Whirlpool water heater right in its place. Easy-peasy. April 6, 2014
nice thermocouple and wires messy not secured with ties or clips . deeply recessed hot and cold bosses require nipple kit unlike rheem. this heater took very very long time for pilot generator to cancel low voltage signal. I never experienced this with dozens of icon equipped tanks ! weak already??? double layers of cardboard from lowes better than home depots ripped boxes.. the little rubber check valves always need to be push deeper to be seated. tanks a lot April 5, 2014
Great buy Water heater went out so I went to Lowe's and purchased this model. So far everything is working OK and I am pleased with this being a short model because the other one was taller. There are also some good features such as the standard and vacation use. April 5, 2014
