The sink is in the powder room on the main floor of our house. When I turn the water on it is fine for a few seconds then it smells horribly for about 3-4 more seconds then it is back to normal. It is the only water in the house that smells, so it's not the water coming into the house. I checked the drain and trap and they are clean and have no odor. I poured water from my kitchen sink down the drain of the powder room and didn't get the odor. So I know the odor isn't coming from the drain or overflow. I plugged the drain and ran the water for about ten seconds and once again got the smelly water. The water in the basin did continue to smell, so I know it is the water coming out of the faucet that smells bad, and not the drain. It doesn't seem to matter if I use hot or cold water. The sink is the closest one to the water heater, if that could make a difference. I'm just not sure where to go from here.

A rotten egg smell in water is usually from high sulfer content in the water. Not unheard of in very hard water. Where it could possibly be coming from in the pipe perplexes me though. The fact that it only comes out one faucet is odd. If both the hot and cold smell bad at only that faucet and no other than the problem must be in the faucet itself, since if it was in the water heater all the hot water in the house would smell and the hot and cold pipes are 2 different pipes until they get passed the supply lines below the sink.
I would shut off the water below the sink, open the valves to drain out any water that might be sitting in the pipe and then see if the faucet outlet itself smells odd. If there is a screen at the mouth of the faucet remove it and see if there is debris inside.
This is hardly an answer but I'd target the faucet or something trapped inside it as the problem.
Love to hear what the problem ends up being.
