I left town for a week and now have a hot water heater that's been sitting and apparently breeding bacteria resulting in an abundance of hydrogen sulfide. It stinks really bad.
I tried emptying it and there was some slight improvement but after 24 hours the stink is back.
I'm now thinking about chlorinating it. Various articles I've read suggest draining a bit of water, removing the anode rod and pouring the bleach in there. I have a different idea and was hoping for some feedback about whether or not this will work and any potential factors to consider.
Immediately before the water heater I have a small 10" sediment filter housing. Can I simply pour the bleach in there and run the hot water to draw the bleach into the water heater? It seems like a simple enough approach but as I wasn't able to find anything online about doing it this way, I'm feeling a bit tentative.
