Great features, easy installation Heater has been in for one week. It took a friend and myself only a few hours to install. Lighting the gas pilot took only a couple of minutes. Lots of hot water right away even on the normal setting. We actually dialed the thermostat down a little and still have plenty of hot water and saving money too. April 14, 2014
Should include installed nipples Had to install nipples on tank and had small leak to deal with which entailed disconnecting water lines to fix. Nipples already installed would reduce install time. I would gladly pay an extra $10 for the tank to reduce install time and headaches. April 12, 2014
product was easy to install and was simple to start up. i do like the blinking light for the pilot. To be honest it is to soon to really rate the product on quality and if I would recommend it. I just replaced one of your water heaters that was warranted for 6 yrs and it went out at 5yrs and 9 months. Thats not a very good product in my opinion. This will be your last chance with me. If it goes out in less than 9 yrs I will find a new company to deal with. Don t take this wrong I am really hoping to be a repeat customer and to one day recommend your product to my friends, family and neighbors. April 10, 2014
2nd time's the charm 1st one was bad out of the box, leaking from the top of the tank where the nipple screws in. The Whirlpool tech support was great and gave me a return number immediately. I just wish the Lowe's rep was as nice. Obviously the biggest issue was the need to drain and disconnect the brand new water heater before returning it. 2nd on worked great and although it has only been installed 2 days, I'm happy so far.

Self installation was a breeze From being well packaged to turning the pilot on for the first time, the whole procedure went well ! April 3, 2014
this product is a failure we bought this water heater just over a year ago and it has broke down twice. it appears to be the same problem I've never had such a poor quality water heater in my whole life. will avoid whirlpools in the future. March 26, 2014
A hot water tank that could have more features! Why do they not put adjustable legs on these tanks so they can be leveled easily? It should have an overflow pipe included with the purchase and female plumbing pipes for easier installation that adapt to 1/2" copper feeds. Why is the drain nozzle by the wiring and cover shield? The plastic manual baggie although it has an adhesive strip easily gets dirt and is too close to the floor. It was nice they gave sheet metal screws for the vent. March 23, 2014
Quick Easy Lowes Installation Just had this tank installed. Heated up quickly and seems like a quality product. I was replacing an American brand water heater to it fit perfectly into the old installation - no issues. (American makes Whirlpool water heaters) the product manual is generic and I was hoping for information specific to my product. Ex: It uses an aluminum anode but this information was not inn the product manual. March 23, 2014
Good features at a good price Just purchased and installed this unit today. Chose the 50 gallon for our growing 4 person family. Install was very easy and straightforward. Disconnect the old, reconnect the new, no surprises. Pilot light lit up first try. Had hot water in about 30 mins. Our old unit lasted 14 years, lets hope this one lasts as long or longer!

Very happy Solid product from an American company with a great reputation. March 18, 2014
