Things Are Smelly Since Hwt Changed


Hi to all, recently I changed our 50 gallon gas HWT to electric. Nothing else has been altered but now we get smelly hot water every 25 days or so. It is only 7 months old now. I have changed out the anode rod just in case but it makes no difference. I've raised and / or lowered the water temp, the heaters are both operating as per the manual as I clipped on a couple of test lites to monitor them over a 24 hour period. The only temporary cure is to drain the tank down at least 1/2 way and refill. Good for about another 25 days or so. Only the wife and I live here. Looking for an answer or an explanation. Thanks

It's called hydrogen sulfide gas, try draining the waterheater completely and add a little bleach solution to disinfect the bacteria in the tank and turn the thermostat up to 160 for a few hours to kill the bacteria, flush the tank real good and see if that works for you

Re: Things Are Smelly Since Hwt Changed


Can this bacteria growth happen within three months of new ?? Is it possible that because I bought a cheaper priced tank I am paying for it now or could it be my water ( comes from a well, no treatment besides a water softner ) reacting with the electric elements vs the old gas burner.

Re: Things Are Smelly Since Hwt Changed


Meaning that the well water is reacting to the electric heating elements as compared to a below the water gas heating element ? We've lived here for 22 years, no smelly water until we changed over to electric so I just want to sorta confirm that it is the heating medium that is causing the smell. BTW the cold water has no smell if that helps to pin point the cause.

Yep bacteria in the water.
do as another poster suggested and run the temps up high for a day ( be careful)
remove the anode rod or replace with an aluminum one if one is made for your tank. These really bring out the rotten egg smell.

Finally replace the tank with a Vaughn stone lined tank that does ot require an anode rod and does not have one installed.

BTW the vaughn's are about 4-5 times as much as the ones in HD or Lowes. but they will last about 4 times longer depending on how aggressive your water is.
