When is the auto ball-drip required on the hookup (dry) side of the check valve for a Fire Department Connection?
In areas prone to freezing, there is the FDC, then a dry portion of pipe, then the check valve. If the check valve is located higher than the FDC (as is typical for our FDCs near risers), can't the connection itself drain the dry portion?
