Vac-Alert is a Safety Vacuum Release
System (SVRS). When a swimmer becomes stuck to a drain or suction outlet
in a swimming pool, spa, wading pool, or hot tub, the force of the
filtration system can be tremendous. This “suction entrapment” will hold
the bather in its grip until either the vacuum is broken, or he or she
drowns, defying the rescue efforts of onlookers. Vac-Alert provides an
important layer or protection to suction entrapment with their safety
vacuum release system.

all requirements of the International Code Council, both the
International Building Code (IBC) and the International Residential Code
(IRC). Meets or exceeds all the ANSI/ASME performance standards for
safety vacuum release systems.
3-year
limited warranty ensures reliability.

ABOUT Unit
VA-2000L
Suction Lift
SVRS Vac-Alert unit - H2O# 4440010
The Vac-alertTM 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 0.170”
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 Vac-Alert recommends
installation of the VA-2000S (even if it's a lift application situation).
ABOUT Unit
VA-2000S
Submerged Suction
SVRS Vac-Alert unit - H2O# 4440015
The Vac-alertTM Model VA-2000S is a Safety Vacuum Release System
(SVRS) designed for submerged suction applications. Submerged suction in this
case applies to all applications where the circulating pump suction is below the
level of the pool water surface. This unit incorporates a 0.375” diameter
orifice opening installed below the surge tube section. This orifice opening is
sized to provide a limited amount of pump start-up surge protection, while at
the same time allowing enough air into the piping system to insure dissipation
of the dynamic suction force caused by the circulating pump.
The Model VA-2000S SVRS unit also utilizes a check valve assembly equipped with
a 0.25 pound spring and a non-vented poppet (no poppet disc or hole through the
poppet). This check valve assembly utilizes a light duty spring to minimize the
sealing force of the check valve. The non-vented poppet insures that water from
the circulating system, under a positive hydrostatic head condition, does not
migrate up into the SVRS.
For pumps operating 24/7 Vac-Alert
recommends installation of the VA-2000S (even if it's a lift application
situation).
