Outstanding Value Our old hot water heater was on its last legs and I was afraid of it failing. It was not a Whirlpool and it came with the house when I bought the house. I went to the store and bought a 40G natural gas water heater with a 6 year warranty on it from Whirlpool. I stand by Whirlpool products 100%. Upon bringing it home and getting ready to set it up I discovered that not only did Whirlpool include a user's manual they included a sort of "quick start" guide to cover the basics in full color. Outstanding! The install was so easy it was unbelievable. Attach the nipples and the new flexible water lines. Connect the exhaust and then the gas line. Fill the tank. Bleed the air from the line via the kitchen sink and then light the pilot. It was so easy that even a caveman could do it! Whirlpool had outstanding directions, hints, and things to look out for in the manual. Even the directions for lighting the pilot and adjusting the temps on the new 6th Sense controls was spot on. I love the peace of mind I now have from my new Whirlpool hot water heater. November 26, 2011
You have a good product. I can't find replacement parts at this time. The Model # is not found in data base's I'm trying to work with. Your product performed flawlessly for the past 3 years (+/-). It quit working recently due to a safety feature of "high temperature shutdown" per the status light code #4. Per my review of your web site (home - learn more - gas water heaters - how gas water heaters work), I deternined that the "energy cutoff switch (ECO)" was activated due to "high water temperatures". The entire gas valve must be replaced for the unit to operate. In my attempt to purchase said valve, no website can reconize my model #. I am not trying to file a warrenty claim. I'm just trying to find a part to "fix" unit. Thanks in advance for all your help. Sincerely, DAG May 25, 2015

I did it I was able to install it on my own. It took me over 8 hours and a few set backs but I was able to figure it out and install the water heater on my own. Saved me about $500 in labor costs to do it on my own. May 22, 2015
