I fired up the Honda 2000 so that I could run my hot water heater over the weekend to do some dishes. The hot water had a very strong sulfur smell. Any idea what would cause this? It was so strong that we could smell it while standing on the back deck. Could there be something growing in my tank? I have been filling up the tank at the same place in Whittier all season. I am planning on running some bleach through the system to see if that kills the odor.
