Odor from faucet
Hi there! I have a private well. There is a hydrogen sulfide smell when I turn on the cold water in 4 of my faucets. The smell does not occur in the tub or shower. When I turn the water on and allow it go in a glass, I can smell a "rotten egg" smell for 3 seconds. It then dissipates. I've had several plumbers out to check the p trap, the plumbing underneath, the condensation lines of the HVAC in the attic above the bath sinks. It's a mystery. Please advise!
