4 Common Causes of Sewer Odor in House

In this article, you will learn:

• Common causes of sewer smells include dry drain traps, missing cleanout plugs, evaporated toilet traps, and damaged wax rings, all of which allow sewer gas to leak into your home.

• Many odor issues have simple fixes, such as pouring water into unused drains, replacing cleanout plugs, flushing rarely used toilets, or stabilizing and resealing a toilet base.

• Persistent sewer odors may signal larger problems, like cracked sewer lines or loose plumbing joints, and professional inspection from ABC Plumbing can ensure a safe, lasting repair.

Sewer odor in your house is often caused by issues like dry drain traps, missing cleanout plugs, evaporated toilet water traps, or damaged toilet wax rings. These problems allow sewer gas to escape into your home, creating unpleasant smells that require prompt attention. Here’s a closer look at these common causes and how to address them.

1. Dry Floor Drain Traps

Floor drain traps are designed to block sewer gases by holding water in the trap. If a trap dries out due to lack of use, sewer odors can enter the room. Simply pour water down the drain to refill the trap and restore the seal.

2. Missing Cleanout Plug

A cleanout plug inside the floor drain prevents sewer gas from bypassing the water trap. If the plug is missing or damaged, odors can escape. Remove the drain grate and check for the plug inside the drain bowl. Replacement plugs are available at most hardware stores.

3. Evaporated Toilet Traps

Toilets that go unused for long periods can experience water evaporation in the trap, allowing sewer gases to escape. Flushing the toilet will refill the trap and eliminate the smell. Regular use or occasional flushing can prevent this issue.

4. Leaking or Damaged Toilet Wax Ring

The wax ring seals the toilet base to the flange, preventing sewer gas from escaping. A broken or leaking wax ring can cause odors and may require replacement. If the toilet wobbles, use shims to stabilize it and prevent damage to a new wax ring.

Other Potential Causes of Sewer Odor

In some cases, sewer odors may stem from more serious issues such as:

• Broken or Cracked Sewer Lines: Damaged sewer lines can release gas into your home. These issues often require professional inspection and repair.
• Loose Connection Joints: In rare cases, loose plumbing connections inside walls can allow sewer gas to escape. A plumber can locate and fix these hidden issues.
