Simpe straightforward installation. Also installed circulation pump which made a huge difference in availability of warm water at remote faucet. Great combination. Couldn't be more pleased

Rated 1.0 out of 5.0 by Steve Product started to leak within months. Rheem pays just for the gasket - "Parts only warranty"
Warranty is limited to "Parts only", no matter how old the unit is.

Rated 3.0 out of 5.0 by Eldon Lifetime Warranty*
I bought 2 of these recently. I'm not sure how well they will last and I'm not sure why you need to register them to get a lifetime warranty or why they cost so much. Will I own the house in another 10+ years to see if they last longer than my last ones??? Maybe. The reason I bought them was because my plumber recommend them because of the lifetime warranty, but even he has no idea how long they will last. Here's hoping....
The only reason I rated this medium and not higher is because it is newer and I have really no idea how long it will last or how it is performing compared to my old one.

Rated 1.0 out of 5.0 by Joe56 Failed in 4 years.
I had this installed in my new house and after 4 years it is DEAD. The Warranty Page won't actually show you the warranty, and the warranty verification tool says it can't find the status of my hot water heater, even though the marketing department seems to be able to find its model from my serial number and send me marketing emails JUST FINE.

We've had the Marathon tank for about 2 weeks and can't believe the difference in our water. It comes out hot almost instantly and has improved showering, laundry and dishes. We're very pleased and look forward to many years of happiness with our tank.

Rated 1.0 out of 5.0 by ebbie480 Faulty vacuum valve – beware
Back in March of 2013, I bought a 50 gal. short model electric water heater and I recently discovered (Dec. 2015) that there was a small amount water leaking from the vacuum relief valve on the top of the unit. After some research, my contractor found out that is a common problem, contacted Rheem and they immediately sent out a replacement part at no cost. Unfortunately, I still ended up having to pay almost $400 in labor to replace a faulty vacuum valve that was a little more than 2 years old. I hope this will fix the issue, but I will have to continuously check the water heater for any leaks from this particular valve. Other reviewers have mentioned that they had to replace this part multiple times – which ends up being more costly than buying a regular water heater.

Rated 5.0 out of 5.0 by Big red truck I bought my Rheem when I bult my home 10 yrs ago.
I bought my Rheem 10 yrs ago when I bult my home. Well after 10 yrs later it went out. Rheem was very nice in standing behind there product . They replace my Rheem with no problem. The only thing is you must fill out your warranty form for your new rheem that you receive.
