22.214.171.124* Drainage. The piping between the check valve and
the outside hose coupling shall be equipped with an approved
automatic drip in areas subject to freezing.
In an installation where the FDC check valve is installed at the system main 10'-0" above the floor and the Single Clapper, FDC is located at 3'-0" above the floor, there is no trapped piping and because it is only a Single Clapper FDC, the FDC piping would automatically drain when the fire hose is removed, so there would not be a freezing condition, would an Approved Automatic Drip in areas subject to freezing still be required?
