Deflation via Powerline Dump Valve

Inside the power inflator’s corrugated hose is a cable that attaches the power inflator to the Powerline Dump Valve at the top of the airway assembly.  You can vent air from the BC by firmly pulling straight down on the power inflator. This dump valve provides an effective and convenient way to vent air from the BC while in either an upright or facedown swimming position.
