When we take longer showers or really hot showers, we notice that sulfer rotten egg smell a bit. I know that this can be a hard thing to diagnose. A lot of people have said that it could be a bad rod in the water heater or bacteria in the well. I have bleached the well about a year ago, but haven't checked the rod in the water heater. I am thinking about checking our roof vents tonight to see if there is a possible obstruction in one of the vents. Is it possible that this might cause the smell?

A bad trap, clogged vent or bad toilet wax ring would all cause a sewage odor, not rotten egg. Rotten egg is hydrogen sulfide, more likely bacteria in well, water heater or bad rod (sacrificial anode) http://www.mrwa.com/watersmellrotteneggs.htm
