Hi,
We have RV'd for years but recently our hot water and probably the tank has smelled like sulfur. This Montna is but 4 years old. I have changed the anode with not lasting results.
Is there a way to cleanse & sanitize the Hot Water tank in my Montana?
(No I am not interested in buying a new tank or selling the whole she-bang!)
Thanks,
Flytyr
