Rated 5 out of 5 by Easy, Straighforward Install & Water Heater Working Great So Far.... Our old water heater went out Saturday (no warning, just kaput -- woke up to cold water showers and wet garage floor) and on a weekend (never fails) so we had a few days of cold showers, etc. It lasted 14 years and had a 5 year warranty, so I guess it was long overdue to die. At first I was thinking we'd need a pro install and that is M-F I believe (ended up installing myself however on Mon. aftn.)....so during weekend, I went online and checked out lots of brands, Rheem came up shining in the customer reviews department. So on Monday morning I went to the Home Depot nearby and chose this one.... It was in my garage waiting for me when I got home from work (wife took free delivery) and I installed it same afternoon. I would have done this the day the old water heater died but I was thinking I'd need a pro installation at the time, not having confidence to do it myself at first. As it turned out, the whole install took about 2 hours (have done a few projects, but not an expert DIYer by any estimation) with the instructions being very detailed and straighforward (mostly involves reading the inst. thoroughly and being sure to attach all the connections properly. I had a bit of concern since I have never installed a water heater before but forged ahead and everything went fine..... it is heating away as I type. There was warm water within an hour and it was actually too hot later in the evening (temp dial was at about 3/4 of the way up to heat the first fill of water) so I turned it down 2 notches before bed ...and it was still plenty hot for showers next morning and dishwashing and one hot load of laundry. I would recommend this water heater and I will update if anything changes, but so far it is chugging away and heating great (see my post-installation pictures attached) So, bottom line, don't be afraid, just read the instructions thoroughly (very detailed) and you'll be fine. If I can do it anyone can. July 1, 2014
Rated 5 out of 5 by Works great so far. I installed this myself about 3 days ago. So far, it seems to be working great. It does not cycle on nearly as much as my old water heater. I did swap out the cheap plastic drain valve that comes factory installed with a brass valve. If I have any problems, I will update this post, but overall it seems to be a good buy. May 29, 2014
Rated 1 out of 5 by Defective ignition system I installed this water heater a month ago, and it has a serious defect. There is a delayed ignition problem that causes a loud explosive bang when the gas ignites. I called Rheem, and they are aware of the problem, although they continue to sell them. Their solution is for me to hire a tech to come out and fix it, after I hook them up with Rheem to find out how to fix it. Even though I live in a city of 400,000, there is no Rheem service tech in this area. I have to pay for the repairs, then send the bill to Rheem, and they will pay for repairs up to $125. They would only give me a fax number and an e-mail address. Run, don't walk, away from this firetrap. April 11, 2014
Rated 5 out of 5 by Great Product. Only problem with install was we had 3 old men that would make the three stooges look like genius, and we still got it done with out too many problems June 3, 2014
Rated 4 out of 5 by Typical Installation The factory attached dielectric nipple at the top was leaky. Removed nipple from tank and applied teflon thread tape before reinstalling nipple and tightening into the tank. Solved problem. Also it is not uncommon for the water shut off valve to be broken in the water supply plumbing. I used a new ball valve with easy install shark bite connections. The gas water heater installation kit I bought from HD was handy too. It had all the remaining supplies I needed. May 16, 2014
