Since getting our new water heater in June the hot water has smelled like rotten eggs. Apparently there are bacteria in some water that eats the anode rods and excretes a harmless but nasty smelling gas. This never happened before so I’m guessing the new water heater used a different anode material. Apparently that’s a thing. So my weekend project was to install an electric anode rod which is supposed to solve this. We shall see.
