Water Smells!

About 2 months ago, we noticed the hot water, from the sinks and shower smelled like rotten eggs. It seemed to go away by the end of our trip. We havenít used the DP since and while winterizing the rig today, and letting the water out of the water heater, the water smelled like rotten eggs again. We donít use the motor home often, so it sits for months. I sanitized 1x before we took our first trip this summer, but really donít yet know how this happened or how to prevent it. Any thoughts?

If your HW heated is equipped with an anode you might try replacing it if is old. There are reports of old ones causing that smell.

Drain and flush water heater after each camping trip

Rotten egg smell is sulfur microbes and hydrogen sulfide gas
Could be from water source
Could be reaction to metals in WH Tank
*especially if WH is Suburban with a Magnesium Anode Rod and sourece water has high sulfides

Yup, bacterial microbes in water heater. Drain water heater and change anode rod if equipped. Drain and sanitize the whole system including the water heater with bleach water, (1/4 cup for every 20 gallons of capacity), and let sit overnight.

If you use well water you might consider draining after each trip.

Thanks everyone for the responses. The WH does not have and anode rod, but the last batch of water did come from our home, which is well water. We never get this smell @ the house so I never suspected that might be the issue.

We'll start purging the water heater more frequently and will sanitize more than 1x per season.

Thanks again!

we have had that twice. both times it was from untreated well water, never from city that had been chlorinated. once from a casino in the country. I now ask if there is any doubt.
