What Causes Sewer Smell In House?

Expert Insights from Prima Plumbing, Sydney.

Are you experiencing a foul sewer smell in your home?

This unpleasant odor can be not only annoying but also a sign of underlying plumbing issues. At Prima Plumbing, your reliable plumbing company based in Sydney, we understand the importance of maintaining a fresh and clean living environment. In this blog, we’ll explore the common causes of sewer smells in your house and how to address them.

COMMON CAUSES OF SEWER SMELLS IN THE HOUSE

P-traps are U-shaped pipes found under sinks, showers, and bathtubs that hold water to prevent sewer gases from entering your home. If a fixture hasn't been used in a while, the water in the P-trap can evaporate, allowing the smell to escape.

Simply running water into the affected drain can often resolve this issue.

Vent pipes allow sewer gases to escape from your plumbing system. If these pipes become blocked by debris, leaves, or even bird nests, the gases can be forced back into your home, causing a foul odor.

Clearing the blockage from the vent pipe can help eliminate the smell.

Cracked or broken sewer lines can leak sewer gases into your home. This is a more serious issue that requires immediate attention. If you suspect a sewer line problem, it's crucial to contact a professional plumber for an inspection and repair.

Clogs or buildup in your drainage system can cause a sewer smell. Grease, hair, and other debris can accumulate in your pipes, leading to blockages that trap sewer gases.

Regularly cleaning your drains can prevent these issues.

The wax seal at the base of your toilet creates a barrier between the toilet and the sewer pipe. If this seal is damaged or improperly installed, it can allow sewer gases to escape into your bathroom.

Replacing the wax seal can solve this problem.

Food particles and grease can get stuck in your garbage disposal, leading to unpleasant smells.
Cleaning your garbage disposal with a mixture of baking soda and vinegar, followed by hot water, can help eliminate the odor.

Biofilm is a slimy substance that can form in your pipes and drains, harboring bacteria and causing bad smells.

Regularly cleaning your drains with a natural enzyme cleaner can help prevent biofilm buildup.

David from Prima Plumbing did an excellent job! He was professional, reliable, and went above and beyond to make sure everything was done properly. Even though it was already dark, he stayed and got the job done. David came back to check up and follow up afterwards to make sure everything was working well and that I was happy with the service. That level of care is hard to find. Highly recommend David and Prima Plumbing 👍

Had an emergency over the weekend with a burst hose underneath our bathroom tap. Water was gushing everywhere! Called David and he was able to attend as soon as possible. From the moment he arrived, David’s professionalism, reassurance and friendly approach not only made my family feel at ease, but also gave my mum real confidence and peace of mind in her own home. He quickly identified the problem, fixed it efficiently, and explained in simple terms what had happened and how to avoid it in the future. What stood out most was how thorough he was, checking everything carefully to make sure there were no other hidden issues. He treated our home with respect, left the space clean and tidy, and even followed up afterwards to ensure everything was still running smoothly. It’s rare to find a tradesperson who is this reliable, trustworthy and genuinely caring. I wouldn’t hesitate to recommend David to anyone looking for a skilled plumber who goes above and beyond.
