Rated 2.0 out of 5.0 by Horrible Water Heater I bought and installed this water heater at the end of June 2014. It went in easily and worked fine for those first five months. Unfortunately this past weekend, the water heater began tripping the breaker. I used a multi meter to test the heating elements and got a reading of 12 (normal) on the lower element and 195 (NOT normal) on the upper unit. Being that this heater is only 5 months old, I called the number to make a warranty claim. They told me it was the heating element and they would overnight a new one to me. Three days later, the heating element came and we installed the new one. The old one was completely corroded and burnt up even though it is only five months old. After doing all of this, the water heater is still tripping the breaker. The warranty is basically useless. Even though it is less than a year since purchase and installation, they will only send parts for what the problem may be and not pay for labor to fix it. At this point, it will be cheaper to replace the water heater with a non-Rheem brand than it would be to call someone to come out and look at it. November 25, 2014
Rated 4.0 out of 5.0 by Good for the money This is a good tank for the money. With a few tweaks, it can be made into a very good tank. That said, If you want a great water tank, get a Bradford-White (the Mercedes Benz of tanks) but it will cost you $600 vs $238.00. Forget about the 6/9/12 warranty issue. A water heater is basically a water heater. They pro-rate the replacement and by the time you pay someone to install the new tank, there is no benefit. Sure, high-end tanks have better anode rods and more bells and whistles, but..... Here's a few ideas to get more bang-for-the-buck. Take out the heating elements that come with tank and throw them away. They are junk. Purchase (2) Camco Stainless replacement heating elements and install them on the new tank. They are $11 a piece and hanging on the rack right above where the water heaters are displayed. Also, purchase a brass drain valve and install it on the new tank in place of the plastic valve. It costs $7 and is hanging on the rack in the same place. For $29 you now have a 12 year heavy duty tank. Lastly, remember not to do any soldering near the hot and cold inlets on the top of the tank. They contain plastic parts and if you melt the plastic you ruin the tank. Do your soldering on the workbench and then screw the nipples on. AND.. a very important tip, any screw-on fittings need to use Teflon tape AND great white pipe dope applied on top of the Teflon tape. Teflon tape alone will leak and you will have to start over, no matter how much pressure you apply. I know plumbing purists will argue with me, but I don't have all day to stand around trying to stop a leak. September 13, 2014
Rated 2.0 out of 5.0 by Very Very Bad Experience Installed heater and turned on water. Immediately had water streaming from upper heating element. Pulled element to find that no required gasket had been installed. This defect would have easily been found with a quick, simple, inexpensive leak down check on the assembly line with compressed air. Called Rheem and they said they would overnight air me a new element. I received the element 4 days later. They made no offer of furnishing labor as I would assume they would. So much for their one year labor warranty. The lack of a gasket on the element has left me wondering about their quality control in the factory. I will not buy Rheem again as there is too much bad being reported in the reviews. September 15, 2014
Rated 4.0 out of 5.0 by Rheem 40 Gallon Electric Water Heater Easy to install; working fine so far (the water from the tap takes awhile to come up to temperature, but that may be the fault of our house's plumbing, not that of the water heater. November 5, 2014
Rated 1.0 out of 5.0 by save your money dont buy rheem The worst product i have ever bought. Also worst customer service. I bought a rheem hot water heater 40 gallon electric nothing but a nightmare i could not trouble shoot the problem with the unit i replaced both heating elements i replaced the electrical unit inside the top cover i still saw no results the water inside the actual tank is scorching hot but no how water in the house i thought maybe i mistakenly hooked up the hot water to the cold water inlet but thats not the case i still couldn't figure out what the problem was. I scraped the unit and got a better brand. I guess i got what i played for. Save your money get a different brand im never buying rheem products ever again. February 22, 2015
