What is a Safety Vacuum Release System (SVRS)?
A Safety Vacuum Release System, or SVRS for short, is an anti-entrapment device that automatically stops the suction on the drain when resistence to the suction force is detected due to a blockage. If a drain becomes blocked, the SVRS provides a rapid vacuum release, either electrically or mechanically, depending on the device. This vacuum release quickly frees anyone whose body, hair, or limb is caught in the drain.
