"4 year life expectancy?"
4 years ago, I replaced my old water heater (I don't remember the brand) just simply because it was 21 years old - it never had a problem. Four days ago, the new 48-gallon Rheem water heater failed. The technician replaced the pilot assembly and the gas control unit, but the water heater would not maintain the pilot light. Rheem replaced the water heater (charging a $100 "upgrade fee" and of course $400 for the technician) - Rheem honored the warranty otherwise. So, do I expect a four year life cycle for the water heater (and a $500 expense every four years)?

"Rheem 40 Gallon Gas Water Heater"
My last water heater was not very old and stopped working without warning. I had to get one right away so I went with the one my trusted plumber recommended. I have had this one now for about five years and have had no problems with it. It keeps up with our family of four, which includes two teenage football players, without issue. I am able to turn it down any time we leave town to cut down on the expense but I have found this one to be somewhat less expensive to run than my previous one. The last one was only a few years old but not very energy efficient. I have never had a problem with the pilot light going out, which had happened with my previous water heater. This one gets the water very hot, to the point of scalding, if I have it up too high. So I am careful about the setting. If you are looking for a dependable gas water heater, I would highly recommend this Rheem for being inexpensive and dependable.

"Rheem pilot light goes out"
I bought a Rheem water heater 3 weeks ago. The installation went well. But then the pilot light went out the next morning. I restarted it right away. After 1-3 days it keeps going out. It never stays lit. I called Rheem - they told me that they would replace it or fix it. They told me to get a plumber to come out. The plumber called up Rheem and told them that everything was hooked up properly but it is not working correctly - that it needs to be replaced. They told them that there was a tiny leak in the water that they tightened and fixed instantly but it had nothing to do with the problem. Rheem told them that it is not covered now because there was a water leak. I can't even begin to tell you how small this leak was. It was nothing. Rheem was just looking for any excuse not to replace it. They are such a joke. I would never buy another Rheem - I would never recommend one. My plumber kept telling them that the water had nothing to do with why this is not working. But they didn't care. They told me to go buy another one. Horrible customer service, horrible product. Stay away from Rheem. Even my plumber told me that I should have read more reviews - most of their repairs are for Rheem.

"Don't get"
I just bought a new Rheem 38-gallon water heater from Home Depot. I took it home, hooked it up and within 1 hour it was broken! I called Rheem, thinking it would be something simple to adjust or reset, but no, the unit was broken. The pilot assembly needed to be replaced; it only worked for one hour! Then the customer service rep told me that I could not return the unit to Home Depot, that they had an agreement with them and they would not take it back! She wanted me to wait for a week while the part was shipped from back east. In the meantime, my family and I have no hot water! Home Depot took it back with no problems and that will be the last Rheem product I ever buy ! Do yourself a favor and do not buy anything with the name "Rheem" on it !

Other Professional Reviews

Among the very few online reviews of the Rheem Professional is one on rigidforum.com from a homeowner who states that he just had the drain valve assembly on his electric tank fail for the third time with a crack where the nipple threads in. Based on the responses, it doesn't sound like this is a common problem with this unit, though.

Professional Warranty

  • Up to 12-year tank/heat exchanger warranty
