I have a sulfur smell coming from a cold water facuet in my bathroom. This is a new home with Moen faucets. The the odor started shorlty after moving in. I'm on city water and the water supply lines are the standard blue plastic/PVC lines (believe there is another name for the plastic ? pex- not sure). The odor is only on the cold water side and only comes from one faucet in the home. I installed an under-counter water filter but this didn't help. The odor is not from the drain. I've taken a sample in a glass to another room and the odor is definitely in the water. Someone in another forum reported a problem with the plastic tubing used in Moen faucets. Looking for advice from anyone with a similar experience.
