Mildew smell from hot water
Recently I returned home after being gone for couple of weeks. My wife and I have noticed a pungent mildewy type of smell that seems to be coming from the hot water only side. (40 gal, natural gas heater, on city water). The smell is more musty/mildewy than like sulphur. I did some minimal research and didn’t find a lot of info, with the exception that maybe some bacteria has formed in the tank…
Possible remedies are:
1. introducing a couple of liters of hydrogen peroxide into the tank and letting sit for about 4 hours, then flushing.
2. Replace anode rod with a powered anode rod.
Anyone out there have any insight on this?? Would be much appreciated! Thanks so much!
