The Flat E-Valves also function as overpressure relief valves.
CAUTION: The proper function of the overpressure relief valve is vital to preventing damage to the BC bladder. Unauthorized service or tampering may render these valves inoperable, and could cause the bladder to leak or burst. This type of damage is not repairable, and is not covered under warranty.
WARNING: Most training agencies recommend that you descend in an upright, feet-first position, in order to maintain a slower and more controlled descent. This is especially true if you experience difficulty equalizing your ears, or if you are descending in low visibility conditions.
