Vented Flow Control Assembly, 100 gpm
Sometimes space restrictions require the installation of Big Dipper and Trapzilla units in basement locations where significant head pressure becomes a factor. The VFCA-100 Vented Flow Control module provides an option for use with installations where significant head pressure is present (greater than 6' [1.95 m]) or where applicable regulations require vented flow controls. The Vented Flow Control helps reduce problems associated with high head pressure and helps slow the drainwater flow down the pipe, preventing it from exceeding 100 gallons per minute (6.31 l/s). Includes appropriate PVC fitting and flow stainless steel flow control orifice.
