Bypass HC Flow Meter Using Shutoff Valves
A second option would be to install PVC tee-ball valves on each side of the meter. This is
the recommended option during NEW installation. The meter will have to be removed
manually after the blowout to make sure any residual water is not sitting inside through the
winter months.
