Sulfur Smell in Water

[Ourfiver]

I have experienced this from my bathroom sink. After searching and cleaning tanks, etc. I found that the source of the odor was coming from my 2 low point drains in the front of my Eagle Lite 5th wheel. By running treated water (with bleach) from my fresh water tank, opening the low point drains and repeating that process a few times I am able to keep it clean. Once a year has been enough for this but during the camping season I routinely drain the water from those 2 points after each outing. Works for me.

We have had the same problem thought it was the hoses replaced them still had smell. Talked to others and they asked if I drain the hot water tank after use nope I don't they then told me I should as this is where the smell is coming from. So now after every trip when I get home I open the drain on the water heater and have not had the problem since.

We experienced this in our house rather than our trailer. A good test to try before questioning your water supply is run the tap into a cup and smell it. In our case the glass of water smelled fine. Poor the same water down the drain and it would smell.

So in our case the sulphur smell was coming from the drain not the taps.
