Sulphur water can be caused by a chemical action or by bacteria. The solution to eliminate is chlorination of the water system. Add about six (6) ounces of chlorinated common household liquid bleach to each 10 gallons in the water tank. Then run the chlorinated water throughout the system, opening each faucet one at a time until you smell the chlorine. Let the RV sit for a few days and the chlorine should take care of the problem. Then you will need to take care of the chlorine. Remove the chlorine by flushing the system with fresh water. This may take several attempts. You may consider adding a filtering system that removes chlorine and prevents sulphur water. If the sulphur or rotten egg smell continues, flush the system once again as described above and replace anode rod as necessary.
Thanks Dan. What do you suggest as the best way to add the bleach solution into the tank?
We are staying in the unit now so it sure will be inconvenient leaving everything sit for a few days.
Sewer and grey tank valves are kept closed.
Dan, from your reply am I to assume that it is the hot water tank which is most likely the source of the bacteria.
Do we know how this bacteria affects humans and how to cure any symptoms
If there's no anode rod, you must have an Atwood Water Heater. Suggest you look in the Atwood manual for their instructions on cleaning.thank you for the inputs.
My water heater does not have anode rod. We do not use fresh water tank, have always been hooked to city.
Guess bleach rinse is the only option.
