Cold water sulphur smell

[Jdmcla]

Good morning all. Hoping everyone us having a great start to their weekend, and everyone travels safe. My concern is, I've got that funky sulphur smell coming from the "cold" water of my sinks, toilet, even refrigerator water dispenser. The hot water doesn't seem to have this so I'm assuming that the bacteria is being killed in the water heater.

Looking for recommendations on how to kill the smell. Side note: I've got a water softener and have flushed/recharged it recently with no effect on the sulphur smell.

I had that similar issue, but no softener. I sanitized the water system with the recommended bleach solution and it was gone quickly.

First question, where is your cold water coming from? City, well, ???

We had the same issue with our Pinnacle at the end of last camping season. Even the ice cubes smelled like sulphur. Of course we winterized it then. This spring I followed the steps for sanitizing the system. I never had this problem in my TT. We don't camp but 1 or 2 times a month. IMO this allows water to sit in the filters of the water system. So I'm thinking the bacteria has a chance to form in the water filter between the city water and the faucets inside the RV. I also think bacteria can form inside the water filter on the residential fridge. After sanitizing the system, the smell was gone. I'm trying to limit the opportunity of bacteria forming by removing the filters after each trip and draining the water from all the lines.

I hope this helps.
