Top 6 Causes of a Sewer Smell in Your Bathroom

A leaky toilet base can cause a sewer smell in your bathroom.

What's causing that bad odor in your bathroom? If you notice a sewage smell for more than a day, it's a sign of a potentially serious issue in your plumbing system.

Here are the top 6 causes of an unpleasant sewer smell in your bathroom:

1. Sewer line issues. Many Dallas-Fort Worth homeowners experience sewer line issues due to cracked pipes, tree root intrusions or clogged pipes. Improper flow through your main line causes sewer backup into your drains.
2. Clogged drains. Wastewater collects when a clogged drain pipe backs up — in your bathroom, this means that toilet water, shower water and soap scum don't safely leave your home through the sewer lines.
3. Leaky toilet seal. The wax ring between the toilet base and flange establishes a watertight seal that protects against wastewater and bacteria buildup. A worn-out seal allows water to leak out around your toilet bowl.
4. Biofilm buildup. Biofilm is a thin layer of bacteria that accumulates in old, clogged or dirty drains. This slimy film collects in a floor drain and releases a foul odor that smells like sewage.
5. Damaged vent pipe. Air is essential to proper drainage out of your bathroom. A blocked or damaged vent pipe creates a vacuum that dries out your P-trap. Debris in your vent pipes also prevents bad odors from leaving your bathroom.
6. P-trap issues. A P-trap is a U-shaped pipe located under your bathroom sink or tub. Its job is to trap water and create a seal that guards against sewage gas entering your home. If the P-trap dries out completely, gas can escape your sewage pipe and release back into your house.

Do you have cracks or blockages in your sewer line?

Sometimes, unpleasant bathroom smells are a superficial sign of a serious issue in your sewer line. The main sewer line carries all your wastewater and sewage away from your home and safely to the public sewer system or septic tank.

Here's how sewer backups, blockages and pipe cracks cause unpleasant smells in your bathroom:

• Sewer backup means your waste (and its smell) have nowhere to go except back into your home — usually through your floor drains. Waste decomposes in your drains instead of safely away from your home. This causes the release of toxic gases like methane and hydrogen sulfide, which is responsible for those nasty odors.
• Sewer blockages require immediate attention. These wastewater flow obstructions are caused by debris, organic hard mineral deposits, and tree root intrusions. (In Dallas-Fort Worth, live oak roots are often to blame.) 
• Sewer pipe cracks allow sewage gas to escape into your home and your yard. The appearance of pests near drains in your bathroom is a telltale sign of cracked pipes, and immediate sewer repair is necessary.
