I like this water heater.
I think I can use this water heater for more than 10 years. It is a good value. Except for one thing I found. The water leak from the top heating element wasn't tightened enough. Opened the top cover because the felt water was too hot and tried to reduce the temperature. After the top cover removes, the sponge was wet. It is leaked. Price and it working good. Must check every element which are parts of main after installed. Problems are growing in hidden areas...

21 yrs on old water heater not too bad. This one was very straight forward to install. It was a bit taller than the old one but only by about 2” so no problem. Heats water quick and with luck it will last half as long as older one.
Easy straight forward stall

Spend the extra $ on something better
Replaced a less than three year old water heater of the exact same model due to the bottom rusting out.
The first one was leaking terribly through the seams at the top of the water heater. The second one has incomplete threads on the cold side and needed to be returned. Now on the third one, the relief valve is allowing water to accumulate at the top and where the electrical connections are located.
These water heater are either complete junk or HomeDepot received a batch of crap.

Great Performing Water Heater But....
I purchased the Rheem Performance 40 gallon electric water heater based on my research and the recommendations of a good friend; he’d just bought and installed the 50 gallon model. The Rheem 40 gallon heater has many of the features I wanted: dual 4500 watt heating elements, one year in home labor and six year limited tank and parts warranties, all for a decent price. While the unit has performed flawlessly, I did have two problems with the installation, both stemming from the factor installed tapered threads. The first being upon opening the box the threads were not properly cut, the second was the tapered threads were not compatible with American made adapters; the two combined for a two hour delay. I also decided to install an Intermatic timer which, according to research and reviews should save enough electricity for my wife and me to pay for the water heater, the timer and the plumbing supplies. While still new, I am very satisfied with the heater’s performance but caution the buyer to check the threads for damage and fit to the connecting adaptors before leaving the store!

So far so good.
Just installed it about 3 weeks ago, so far so good! I hope it will last as long as my previous water heater. We had 9 people at our home over Christmas and never had a hot water issue.

Within 1 Yr: Replace the Upper Heating Element
Easy to set up with instructions. The unit worked great for 8 months. The upper heating element was completely corroded & had broken at the bend. Further, the unit leaked from the upper element. Easy replacement, yet why was this unit so poorly made??

Not a top quality water heater but does the job so far
These Rheem water heaters are the high volume/lower cost offerings. Mine had a very slight leak at the front panel for the upper thermostat/heating element. Did a leak test as directed by Rheem customer service and didn't detect a leak issue. The water seemed to be coming from somewhere between the tank and the outer shell. The insulating foam was wet and would trickle down the front of the water heater every once in a while. I'm assuming the water was trapped inside from factory testing or it was due to very high heat/humidity at the time of the install resulting in condensation. One other slight annoyance was how easily the thermostat/heating element cover plate screw stripped out even as I was being extremely careful not to overtighten.
