Bacteria growing in the drainnBacteria growing in the drain is the most common reason for this smell. Over time, organic matter, like food waste, will accumulate on the walls of the drain and act as a nutrient for bacteria to grow. The bacteria can produce a gas (sulfur) which smells like rotten eggs or sewage.Jul 22, 2019,
Clear and Clean Your Water Heater: If the smell is coming from your water heater, turn it off and flush it entirely. Once empty, refill it, turn it up to 160 degrees, and let it run for several hours. This is usually enough to kill any bacteria.Feb 27, 2020
Disinfect and flush the water heater with a chlorine bleach solution. Chlorination can kill sulfur bacteria. If all bacteria are not destroyed by chlorination, the problem may return within a few weeks. Increase the water heater temperature to 160 degrees Fahrenheit (71 degrees Celsius) for several hours.
The easiest way to eliminate a foul odor in your home's water supply is to run all the faucets for around 10 minutes. Running water from every faucet can clear out the rotten egg smell.May 22, 2020
Aeration. Since hydrogen sulfide occurs as a gas in water, it can be physically removed by injecting air into the water and allowing the gas to escape. Aeration units may work by cascading, bubbling, or stripping the gas from the water.Mar 2, 2022
If the smell is coming from faucets in just one area of the home, this is possible; hydrogen sulfide gas can rise and find least point of resistance, sometimes, only one faucet.Jan 23, 2020
One of the common reasons is drain obstacle or drain clogs. An block in the drain will often prevent water from flowing freely through the pipes. Oftentimes, the water become stuck along with other solid materials. And once these materials start to rot or decompose, it produces a poop-like smell.
The incidence of rotten egg odor or black water in hot water lines is due to the reaction of sulfates and micro-organisms in the water that create Hydrogen Sulfide (H2S). This is a water chemistry condition, rather than a water heater problem.
Bacteria growing in the drain: This is the most common cause of these types of odors. Over time, organic matter such as hair, soap and food waste can accumulate on the walls of the drain. These deposits serve as a food for bacteria to grow. The bacteria can produce a gas that smells like rotten eggs or sewage.
