How Mainline Backwater Valves Work | ExpressRooter Toronto Plumber

Marcin from ExpressRooter, the official contractor for Mike Holmes, is here to answer a common question for many homeowners - how do mainline backwater valves work?
Using mainline backflow valve protection, a backwater valve is installed where the sewer exits the building on the main-building drain. There are several benefits and advantages of putting a backwater valve on the main-building drain:
Only one backwater valve is required for the entire building.
The entire building is protected from backflow.
It is conveniently located where the main-sewer cleanout is.
It is easy to locate and access.
