What is a toilet vent?

A toilet vent is a pipe that allows sewer gases to escape from the toilet bowl and prevents them from backing up into your home. It is also known as a plumbing vent or a sewer vent.

Toilet vents are typically made of PVC pipe and are installed in the wall behind the toilet. They extend from the top of the toilet bowl to the roof of your home.

The purpose of a toilet vent is to create a pathway for sewer gases to escape from the toilet bowl and prevent them from backing up into your home. When you flush the toilet, the water in the bowl creates a vacuum that draws air from the vent. This air helps to push the waste down the drain and prevents sewer gases from backing up into your home.

Why do toilets need to be vented?

There are several reasons why toilets need to be vented.

• To prevent sewer gases from backing up into your home. Sewer gases are harmful to your health and can cause a variety of health problems, including nausea, vomiting, and headaches. They can also be flammable and explosive.
