    Thank you for explaining that a backflow preventer, like a check valve, guarantees that water only flows in one direction and its purpose is to keep water flowing from the water main to the pipes of a structure. My husband has been telling me to install a backflow preventer on our system. Knowing what it can do, I should tell him to go for it and hire a plumber near my place to do the backflow preventer installation.
