Foul/Sulfur/Rotten Egg/Sewage Odor
If the odor is a sulfur/rotten egg or sewerage smell that you only smell at the sink and not in the glass you can easily remedy this by applying a small amount of bleach into the drain trap at bedtime and let it stand through the night. Do not run the water until morning to give the bleach time to kill the bacteria (the cause for this odor) in the drain. This may take more than one application.
Cold Water: If the odor is coming from the water in the glass, please call MCWD at (760) 934-2596 to report the issue.
Hot Water: If you find these odors in your hot water only, it may be an issue in your water heater and we recommend that you contact a licensed plumber.
