Hot water smells like sulfur.


Our hot water smells like sulfur, but the cold side is fine. What could cause this problem?

That's what we thought, but the water heater is only 4 months old.

Actually we changed the water heater because the water smelled like sulfur, and the new one was fine for about two weeks, after it started stinking we turned the temp up to about 140 degrees and it didn't change anything.

Is there an unused hot water line somewhere which may have filled with air?

Like a bathroom where the faucets are not used?

Laundry?

Etc.

If yes, run the water in those lines to get the air out and flush them.

Magnesium water heater anode rods tend to cause more odors in the hot water but they do a better job of retarding tank corrosion compared with the alternative of aluminum rods.

Yes there's a bathroom that we don't use, and we flushed it today but why would that make the other lines stink?

I don't know???

But I do know of another case where there was a pipe for future use going up to a dead end. There was rotten egg stink in the hot water lines and air in that pipe.

We opened the cap to fill it with water and flush it, then end of smell problem.

And air can get into regular water lines when the water is turned off. So each time water turned off, flush all lines.

Ok I'll turn it up, I'll also check the anode too.
