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.
 

Features and Benefits:

The perfect safety solution for every pump that draws water, including pools, spas, fountains, slides and vacuum ports.
Self monitoring, non electrical and low maintenance.
Easy to install within thirty minutes. An installation DVD is included with every unit. It is recommended to use a pool professional.
Long lasting design features moisture resistant PVC, and stainless steel construction.
Proven to work - some states such as Texas, North Carolina, and other places like Ontario, Canada are requiring commercial pool owners use equipment like Vac-Alert to retrofit pools and spas.
Meets 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.
Won't damage your pump when tripped.

Please read the information below about both SVRS units listed above before making a choice of which unit to purchase.

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).
