What is the temperature of your hot water set at?
I noticed the other day when we were running the hot shower to steam up the bathroom for our son who has a cold, there was an odor (musty/moldy). I thought that it may have been the diaper bin that's in the bathroom, but it happened again last night (we had taken the diaper bin out). So I went around to all the faucets in the house and turned on the hot water and the same smell. Only smell it when the hot water is in use.
What could this be? It's not an egg/sulfur smell that I've seen others talk about.
You need 140*f to kill the things that breed in water heaters. It only takes about 30-60 minutes at that temp but all the water has to get to 140.
