If you have a sewer smell in the bathroom, it needs to be dealt with sooner than later.Breathing in high levels of sewer gas may lead to health issues.Air-borne pathogens may enter your home when the seal that keeps out the gases has been breached, leaving you vulnerable.
First, look for clogs in the drain pipes. This is the quickest and easiestthing to take care of, since all you’ll need is a bottle of drainpipe cleaner.Pour it down the sink and shower drains to eliminate any clogs that might have developed in the pipes and triggered the odor. Carefully follow the instructions on the packing, and make sure that you wait the amount of time suggested before you turn on the faucet. If the water runs slowly, you should repeat the process. Hopefully this is all it takes.
If the odor persists after trying the drain cleaner, the next step is to check for standing water on the floor near the base of the sink and underneath the U-shaped pipeline (the P-trap) under the sink. Run your hand along the length of the pipeline to feel for any moisture.
Typically, a small quantity of water collects inside the P-trap, even when it’s not in use, catching drain gases that would otherwise come up via the drainpipe opening. If the water in the P-trap leaks out and leaves the inside of the pipeline dry, those gases will enter and linger in the air.
Unfortunately, if your drains pipes are clear and your P-trap isn’t leaking, you’ll most likely have to hire a plumbing professional for an inspection to locate the source of the smell.There could be a damaged wax ring where the toiletis connected to the flooring. Simply observe how much water remains in the toilet bowl in between use. If there isn’t an adequate amount of water for a flush, you might have a seal that has been breached, allowing thesewer gas to seep into the bathroom. Another consideration is a clogged or incorrectly mounted vent pipes. These pipelines let the drain gases escape from your home. Repairing them would require special tools and a trip to the roof. If the vent pipes are the issue, finding the source of the smell and fixing the problem is a work best left to a professional.
