I am pretty new to the world of RVing and will no doubt have lots of questions/issues/cries for help coming in the near future. Currently it is the rotten egg smell coming from the hot water heater. We had experienced it in the early summer and followed the welcome advice from the forums. I drained and flushed the water heater and gave it a good dose of vinegar with water (I didn't have any hydrogen peroxide on hand), letting it sit for a while before draining it. Then we ran a good bleach/water mix through the storage tank and lines, filling the water heater with it as well. Everything smelled great but today, as I was readying the motorhome for its first trip south I turned on the water heater to make sure everything was working well and when I turned on the hot water taps out came hot water accompanied by the dreaded rotten egg smell. Any suggestions out there for what steps I missed or for what perhaps I should have done?
