The Tank hydrogen peroxide Reply To: hydrogen peroxide

Hello: The bacteria that cause odor in heaters are anerobic. That is, they don’t like oxygen. Hydrogen peroxide is essentially oxygenated water, so putting it in the tank is something the anerobic bacteria find distasteful 😛

It might be good for you to have a look at the anode from your heater. If it has black goo on it or is smelly, the heater is certainly a source of odor. If not, it may be from some other cause, such as a bad drain or sink overflow. As you say, high hot water use usually prevents odor from being a problem in the heater. If you have a very large heater or multiple tanks, the problem is less unlikely 😎

Yours, Larry
