Dealing with a sewer smell in your home can be unpleasant and frustrating. It’s not just the discomfort of the odor itself but the potential health risks associated with sewer gas exposure. Fortunately, there are effective ways to track down and eliminate these smells, ensuring your home remains a healthy and pleasant environment. 

Here are the steps to identify the source of sewer smell and how to address it.

Identify the Source

Check for Dry P-Traps

The P-trap is the U-shaped pipe under your sinks designed to hold water, creating a seal that prevents sewer gases from entering your home. If a sink, shower, or toilet is rarely used, the water in the P-trap can evaporate, which breaks this seal. Pouring a gallon of water into the drain can quickly reestablish the barrier.

Inspect for Leaks

Leaks in your wastewater pipes could be another source of the odor. These leaks can allow sewer gas to seep into your home. Inspect visible pipes for signs of leakage. If you suspect a leak in an inaccessible area, consider hiring a professional plumber to conduct a thorough inspection.

Vent Pipe Issues

Vent pipes expel sewer gases outside your home. If these are blocked or incorrectly installed, gases can back up into your living space. Check your vent pipes’ blockages, such as bird nests or debris. In case of improper installation, a professional assessment is advisable.

Eliminating the Odor

Deep Cleaning Drains

Sometimes, biofilm buildup in your drains can emit foul odors. Use vinegar and baking soda to clean your drains. Pour half a cup of baking soda and vinegar down the drain, wait an hour, then flush with boiling water. This natural solution can break down the biofilm without damaging your pipes.

Seal Unused Drains

Consider sealing or regularly pouring water for drains that are seldom used to maintain the P-trap seal. Rubber drain covers or plugs can effectively seal drains, preventing odors from rising up.

Repair or Replace Damaged Pipes

If inspections reveal cracked or broken pipes, repairing or replacing them is crucial to eliminate sewer odors. This job typically requires a professional plumber, as it involves complex plumbing systems.

Install a Vent Pipe Filter

If your vent pipe is the culprit, installing a filter can help neutralize the odors before they escape into the air. These filters are available at hardware stores and can be an easy DIY fix for reducing outdoor odors.

Preventative Measures

To avoid future occurrences, regular maintenance is key. This includes routinely cleaning your drains, checking for leaks, and ensuring your vent pipes are clear of obstructions. Additionally, consider using water softeners if you have hard water, as mineral buildup can contribute to pipe issues and subsequent odors.

Ready to Freshen Up Your Home?

Tackling sewer smells head-on can significantly improve your living environment. If the problem persists or you’re unsure of the cause, don’t hesitate to contact a plumbing professional. Ensuring your home is free from sewer odors not only contributes to a healthier living space but also to your peace of mind.
