Abstract:
A press device for valve leakage abatement while piping system maintenance is being performed is disclosed herein. Essentially, the device comprises a frame that can clamp down and provide pressure (and therefore seal) to the valve. The design further includes a vent or a test port to assist in determining if a pipe freezing apparatus is working. Also disclosed is a system for providing pipe maintenance to a water supply line wherein one or more pipe freezing apparatuses are employed in addition to the press device.
