Our home water is from our municipality. There are three bathrooms. The plumbing
in the house is about 10 years old, and it is all copper.

In the upstairs bathroom, two or three times per week, when the bathroom faucet
is turned on, the water smells. It's hard to describe the smell, but it's there.
It goes away pretty quickly. The problem only started in the last six months or so.

I have not observed the problem at any other sink, including ones that are
closer to the incoming supply line under the house. The bathroom is used
multiple times per day.

What could the problem be? Should the water be tested? While we rarely drink
from that faucet, we do use the water to wash hands and brush teeth.

Hot water or cold? Only that bathroom? *I see someone suggested in
could be the drain. Yes, that is possible as water hits the drain it
will send back a burst of air.

The other factor is the water heater. If the anode is corroding, you
get a nasty sulfur type of odor for a few minutes. If that is the
case, replace the anode with a different material.

That would only happen if water temp was set too low, in the bacteria
thrive zone.

But the problem is that those odor producing bacteria live
at normal water heater temps. You'd have to keep the water
heater dangerously hot to prevent it. That's why they sell
replacement anodes made of a different metal to stop it.
