IMPORTANT! If you have an electric water heater made after April 2015 by A.O. Smith, Lochinvar, State, Kenmore, Reliance, American, Maytag or Whirlpool; or Rheem, Ruud, Richmond, or GE, let us know because you'll need a pipe nipple longer than four inches.

If you have a vacation cabin, or a water heater that gets little use and thus, has rotten-egg odor, going to a different kind of anode is usually a waste of time and money. This is the only sure fix. It enables you to easily add peroxide to a heater at the start of your visit.
