Another example of a Backflow device Fail
The first issue is with the non Febco repair Parts. These parts may stop the leak from a frozen Backflow device, but they do not allow the device to prevent against a Backflow incident from occurring.
The second Issue is the non circular disc on the check valve. It is completely misshapen.
When making repairs always use original manufacture parts and always get the device inspected to insure it works properly.
