I bought a five year old condo for college kids. It has the original
electric water heater, with rotten egg smelling water.
The unit does not appear to have an anode.
- 4 cups of bleach (twice) dumped into hot water supply side, works for
a few days.
- ran max temp for several hours, did't work at all.
- flushed unit completely until water came out of the shower head cold,
worked for two days, smell is back.
The neighbors with identical units don't have the problem.
What else should I try?
