    One of our customers just underwent a water supply switch from community well water to municipal RO well water.

    Almost immediately they encountered rotten egg smell on the hot side only.

    County says their RO water is high in sulfur.

    One explanation is that the water heater heats the sulfur and converts it into hydrogen sulfide gas, thus the smell.
    Another explanation suggests that there may be a reaction between the water and the magnesium anode, creating the bad smell.

    We can superchlorinate the water heater or even replace it. The question is with high sulfur content RO water, what is to keep the smell from reoccurring?

    Other possible solutions include:
    1. heating water to 180 to kill the sulfur bacteria
    2. changing anode to another metal
    3. removing anode all together
    4. adding a coconut carbon filter

    Interested to know what others have experienced, or might suggest.

    Thanks for all the excellent suggestions.

    The link to the MN Dept of Health is excellent, and repeats the primary suggestion already offered by posters on this forum!
