DEFLATION VIA DUMP VALVE / FLAT E-VALVE / FLAT VALVE
BC’s have either one, two or three additional Dump Valves / Flat E-Valves / Flat Valves, depending on
the specific BC model. Their primary function is to relieve excess air pressure inside the bladder, but
some may be equipped with a knob and cord assembly and can be opened manually by pulling on the
knob and cord assembly to quickly dump air.
To dump air as quickly as possible, always use the dump valve / Flat E-Valve / Flat valve at the highest
point in the water column. For example, the lower rear valve works best while making a headfirst descent,
or swimming in a facedown position; the right shoulder valve works best when in an upright position.
