Learn about sewer backflow prevention devices
The backflow prevention device or BPD is a device that allows water
and materials that back up to escape from the cleanout rather than
flowing into the home. Many backup prevention device can be installed
by the homeowner or a plumber. If not already installed, these items
will be required if you remodel or add a bathroom to your home.
A sewer BPD is often a mushroom shaped metal device in the yard
near the house or a spring-loaded or weighted cover on a sewer line
cleanout near the house and installed on your lateral connection
to the sewer main.
