    Vac-Alert Lift Vacuum Release VA-2000L

    The Vac-Alert Model VA-2000L is a Safety Vacuum Release System (SVRS) designed for suction lift applications.
    Suction lift in this case applies to all applications where the circulating pump suction is either at or above the level
    of the pool water surface.
    This unit incorporates a 0.170in diameter orifice opening
    installed below the surge tube section. This orifice opening is sized to prevent nuisance tripping of the SVRS unit
    caused by high vacuum surges typical of many pump start-up conditions.

    The Model VA-2000L SVRS unit also utilizes a check valve assembly equipped with a 3.5 pound spring, a poppet
    disc and a one-way (up only) vented poppet This check valve assembly permits continued water flow to the circulating
    pump while the SVRS unit is in the open or vented position.
    The 3.5 pound spring further compressed by the poppet disc, creates enough sealing force within the check valve to allow
    partial water flow to the circulating pump for suction lifts up to 3.5 feet.
    This is critical to the elimination of circulating pump damage that can be caused by a sustained dry-running condition.
    The one-way vented poppet allows the surge chamber to be internally recharged when the circulating pump is turned off.

    For pumps operating 24/7 we recommend installation of the VA-2000S (even if it is a lift application situation.
