What Types Of Backflow Preventers Can Be Installed To Help Protect Our Home?
Pressure Vacuum Breakers can be installed on the water supply line to any landscape irrigation system or on the water fill line to swimming pools. Hose Bibb Vacuum Breakers are small inexpensive devices that are installed on hose bibbs or threaded sill cocks where garden hoses are attached.
What is Backpressure?
Backpressure is created when the pressure in a non-potable system, such as in a recirculation system containing soap, acid, antifreeze, or in a boiler system exceeds that in the potable water system that provides the make-up water to the system. This pressure can force the potable water to reverse its direction of flow through the cross connection. Non-potable substances can then enter the potable water system.
