Where do you install a backflow preventer?
Just so, what is a backflow device and where is it located?
Another common location for a backflow preventer is the connection of a fire sprinkler system to a water main, to prevent pressurized water from flowing from the fire suppression system into the public water supply.
Accordingly, where does a backflow preventer go?
A backflow preventer is a device that's installed on your home's water pipes that allows water to flow in one direction but never in the opposite direction. Its sole job is to prevent drinking water from being contaminated due to backflow.
If you aren't sure, take a look around your basement — backwater valves are usually located in the floor and have a cover that can easily be removed for maintenance. The cover itself is likely round, but there may also be a rectangular panel on top.
