Rotten egg smell in Hot water only
lori43

Two years ago I had to replace my Indirect Hot water tank. About 3 months after installation I started to get a rotten egg smell from my hot water faucets all throughout the house, not the cold. I am on a well, with an iron filter and water softener installed between the well and my hot water tank and boiler. I was told that the 3 magnesium anode rods had to be replaced with aluminum anode rods, which I did but to no avail, it still smells. Also, when I turn on the hot water faucet, it spits and sputters for several seconds before finally smoothing out. I have lived here since 2006 and never had a smelly water problem until after installing the new hot water tank. What can I do to fix this stinky problem? :(

Please read this white paper (PDF) from Rheem. It discusses the issue toward the bottom of page 2.

Their recommended solution is an R-Tech anode rod, developed by Rheem. I have no experience with this anode rod, so I can't give that same recommendation -- it may or may not work for you.

(I do not work for Rheem or anyone that sells Rheem products.)

Thanks, Fencepost, for info on Rheem R-Tech anode rod. In researching this I found out that it will not help in removing the rotten egg smell. I did find out that I may need to install a powered anode rod, which is quite expensive. There is a web site called waterheaterrescue.com that gives a lot of good info regarding water heaters with smelly problems.

I called my plumber friend earlier, and he said that bleaching and chlorinating the tank on a regular basis will help, if the anode replacement does not. There is another option, though not recommended: remove the anode and plug the hole. Your heater won't last very long, but will have good water without the chlorine. Rheem suggests a different anode - try that first.

This bacteria smell is activated by heat, which explains why you smell it only in hot water.
