I see a trend starting in our area where the architect is specifying a remote free standing FDC without a valve pit when the check valve can be placed inside the building. Upon talking to my field superintendent he was concerned that some check valves let multiple gallons of water through whenever a system is drained and refilled and that the remote pipe may eventually fill up and freeze. We were toying with the idea of installing a return bend in the FDC pipe downstream of the check before it leaves the building to help prevent this. A ball valve would be installed between the return bend and check to drain out the pipe. Anyone else have insight on this?
