Sulfur smell from hot water faucets except one bathroom

[Fali12]

We are in a new build (moved in 2020-FEB) and recently had a water softener installed along with a activated carbon filter.

We are now noticing that there is a strong sulfur smell coming from the hot water in our kitchen faucet, guest bathroom sink & tub and utility sink in our garage. The cold water doesn't have any smell coming from any faucets in the house.

The weird thing is that the master bathroom doesn't have this issue -- master bath sits on the other side of the wall where water heater sits in garage. We can use our hot water in master bathroom with no sulfur smell.

Does this sound like an anode issue with the water heater or is something else going on with the pipes that could be driving this smell? I have a disinfectant solution that came with the water softener and going to try it, but I have a feeling this method won't address issue at its root.

It's strange but new homes are PEX or CPVC plumbing which has no impact or creating or eliminating odors. You didn't mention if this a single family home with a well or city water? Two things, place the water softener in by pass mode, drain the water heater (power off of course) and refill the Wh with non soften water. If the smell does not return, drain it again, remove the anode rod and refill with soften water. No oder it is the anode rod causing it. It might be a hassle but no other way to know for sure. BTW, removing the anode rod it can be a bear to remove it. Takes a lot of torque.

It's a single-family home with city water plumbed into the house. I am going to give this suggestion a try and see how it goes! Thanks for the input

Did you mean to say, if the smell does return, then to drain it again and remove the anode rod?

Usually calls for an impact wrench for one that has been in place for a while.

https://terrylove.com/forums/index....heater-no-rotten-egg-smell.77342/#post-571874 states my thoughts on why a long powered anode would be better than a cheaper short powered anode.

Just trying to prove that the soften water is or is not causing the odor with this anode rod. From what you have stated, the odor started after the water softener was added and this test is just to prove that its nothing else, source its the reaction of the soften water. Or just remove the anode rod and run the water to flush the WH but it could be difficult to remove the anode rod so emptying the WH and refilling with hard water is very easy to do. May have to give it a day or two heating the hard water.
