A sewer odor in the bathroom can stem from various sources, requiring thorough investigation and prompt action. The shower drain, accumulating a biofilm from shower products, can emit an unpleasant smell. Cleaning involves removing the drain cover and using a brush soaked in disinfectant. Similarly, a jetted tub may release black flakes due to biofilm, necessitating specific cleaning methods.
A sink clogged with residue can also contribute to the sewage smell; using a mixture of baking soda and vinegar, followed by a hot water rinse, can address this issue. P-traps that are dry, dirty, or missing under sinks or in the floor drain need to be cleaned or replaced to prevent sewer gas from escaping.
Unpleasant odors can also emanate from improperly sealed toilets, inadequately installed or damaged ventilation pipes, deteriorated seals, and faulty wax rings. Toilets or sinks that gurgle may indicate a ventilation issue, requiring a professional inspection of the vent system. Incorrect installation of air admittance valves can also lead to gurgling noises. Dead rodents in the ductwork can also cause unusual smells in your building or home.
Knowing when to call a professional is crucial, especially for complex issues like gurgling toilets or sinks. Prompt investigation and professional assistance are essential to effectively eliminate sewer odors in the bathroom.
