Rated 5.0 out of 5.0 by Home Owner Hot Water Heater Replacement I had to replace my water heater due to its age and it was leaking from the holding tank. I called a plumber under my home warranty plan and was going to have to pay out of pocket about $1300. They were providing the water heater (a low end unit) so that $1300 was mainly what they described as additional work not covered by the warranty. I decided to see if I could tackle the project on my own. Not being skilled at sweating copper lines and having had experience with Sharkbite products when I had to replace a pressure control valve for the house, made this an easy decision. I was able to remove the old tank, a faulty shutoff valve on the incoming water line and the expansion tank and install the new parts using these products in about an hour and a half. The home warranty provided me with a cash payment in lieu of contractor that covered all the parts and then some. Pretty easy choice. I bought the pipe prep tool that trims the ends of the copper pipe as well as a couple of these flex lines, a T connection for the water expansion and a lever action shutoff valve that are all Sharkbite products. Not a single leak! The water heater has performed flawlessly. The piezoelectric starter is extremely easy and makes the lighting of the unit quick and safe. February 28, 2015
Rated 5.0 out of 5.0 by Big Mama! This water heater towered my 17 year old 40 gal A.O. Smith. I have to hand it to A.O. Smith for making a great lasting water heater. Hope this Rheem will last as long. This installation was in the attic, but once I got this beast up there, it was very simple to install. It has a self powered status light that is easy to see from a distance. Ignition switch is also a handy addition... no more long match sticks to light the pilot. Comes with a plastic drain valve. I recommend you replace it with a quality ball valve. This will allow you to drain it during maintenance. More importantly, in case of emergency you have access 50 gals of drinking water! The valves that come with the unit will fail or clog with sediments in no time. Also, the screws for the vent hood were missing, so I had to use the ones from my old water heater. Hence the 4 star in quality. March 11, 2015
Rated 5.0 out of 5.0 by WORKING GREAT I got this unit 3 weeks ago, and my brother in law installed it, so far zero issues. We had hot water flowing in about 1.5 hours after the installation. February 20, 2015
Rated 5.0 out of 5.0 by So far, so good! I was hesitant to buy this unit after reading the reviews one year ago.So I waited until there were more reviews. The reviews became much better with fewer fail rates so I decided to take the plunge. I wanted to buy a Rheem or Richmond brand because my last water heater I installed was a Richmond, (also a product of Rheeem). I had my last one for 14 years and knew it was time to replace it before it started to give me problems. Although I did not want to replace it since after all these years it was working perfectly...if it aint broke don't fix it logic! I knew better though it was ultimately time to replace it. Installation was easy, start up was easy and I have hot water with no problems. Definitely seems like a great product and I hope that this one lasts as long as my previous Richmond...we shall see!!

Rated 5.0 out of 5.0 by Sorely Needed Replacement The only problem was some confusion when my installer went to pick up the water heater without my being present. Otherwise we have been accommodated in every way, and the water heater looks good and is working very efficiently. Thank you. April 14, 2015
Rated 3.0 out of 5.0 by Update to Frustrated - Okay Now Frustrated and Unhappy but Optimistic - Addendum [I didn't see a way to edit my previous review so I'm offering this addendum since there's a happy ending and an upgraded rating.] After reading the other reviewer who fixed his leak, I called Rheem and asked for authorization to aggressively attempt to fix the leak myself, which they okayed. After several attempts using a pipe wrench with a 3' extension lever, I gave up, drained the heater, and took it back to Home Depot for an exchange. To their credit, I received a friendly, hassle-free exchange, including help with unloading and loading. I returned to my home with the new water heater and removed the carton, only to find a large dent (9" wide by 2" deep) in the top corner and the baffle dislodged from the flue! To MY credit, I just laughed, took some pictures, e-mailed them to Rheem, re-crated the heater, and headed back to the Depot. There again, I received a hassle-free exchange and got their last one in stock, down from the top shelf via a forklift. Third time lucky -- from here on, everything went smoothly and my new water heater is working fine. Home Depot was as helpful as I could reasonably expect. In contrast, Rheem's policy that limits the repair cost to a too-low fixed value is not customer-oriented. The exchange process, though straightforward, still took almost two hours including travel time. The customer-centric approach is for the plumber to arrive with a replacement unit, complete the installation, and leave with the defective unit. A procedure to handle the unit's disposition and the flow of cash is up to Rheem, their re-sellers, and their field-support contractors to work out. April 18, 2014
Rated 5.0 out of 5.0 by Pleased with this product I was pleased Home Depot carries this brand as I getting more skeptical of the big name brands as the years go by. I have seen this name in commercial installations and will now get to experience the brand first hand. The water heater installed without any issues as a replacement for an older and broken 10 year old unit. Once I had every thing connected and filled there was absolutely no issues lighting the pilot or getting water up to temp after about 1/2 hour. I have been inspecting it daily and there are no leaks. I think I'll be very happy about this purchase decision. Only regret is I would have liked to explore new on-demand technology but needed hot water in my house that day. January 5, 2015
Rated 2.0 out of 5.0 by Check the water heater for damage inside the box before you purchase The pressure relief valve was damaged and started to pour water after unit was installed and water heated up. I called Rheem to discuss they overnighted a new pressure relief valve, but that would mean no water for 24 hours. I went out and purchased one on my own and installed so I could have hot water for my family. The replacement came the next day, at least now I have an extra in case I need it. Hot water heater has been working well so far......... April 8, 2015
