Raising the temp on the heater to 140f for an hour kills all bacteria in the heater. Just don't let anyone use the water and get burned. You could shut the outlet valve on the heater if there is one.
If the odor is in both hot and cold water, do the bleach in the salt tank water thing and then do a manual regeneration by pushing that button etc..
I turned the hot water heater up to 140 for an hour and then ran the faucets and the smell was still there but only when running the hot water, not cold. I certainly didn't run it enough to drain the hot water tank. Since I was leaving the house for the evening, I then turned up the hot water heater (new) - old replaced due to many issues - to 150, the upper limit - and left it that way for the evening - even this morning the smell - only in hot water seems to be worse.
What would you suggest my next step be?
As I said this was an issue when we first moved it and we drained the tank of the old hot water heater. Then with two of us (my husband and me in the house we were using a lot more water) so it went away for a couple years until he left and resurfaced about 4 months after his absence. Now I use very little water with him deployed.
Should I run the bleach through the water softener or will that do anything?
Thanks for any suggestions anyone can offer.
