What is a Trapway?

A trapway is a U-shaped pipe that connects the toilet bowl to the sewer line. It is designed to prevent sewer gases from backing up into the home. The trapway is filled with water, which creates a seal that blocks the gases from escaping.

How does a trapway work?

When the toilet is flushed, the water in the bowl is drained down the drain, but the water in the trapway remains. This creates a seal that prevents sewer gases from escaping into the home. The trapway also helps to keep the sewer smells from coming up through the toilet bowl.

Trapway Problems

There are a few things that can go wrong with a trapway. The most common problem is a clog. If the trapway becomes clogged, it can prevent the water from draining properly. This can lead to a backup of sewage in the toilet bowl.

Another problem that can occur with a trapway is a leak. If the trapway develops a leak, it can allow sewer gases to escape into the home. This can be a health hazard, as sewer gases can contain harmful bacteria.

How to Fix a Trapway Problem
