Vacuum Detection & Relief

Vacless Safety Vacuum Release Systems not only provide added safety against suction entrapment, but they also act as a drain winterization device a surge suppressor extending the life of your pool equipment. This valve is directly attached to the pump by removing the suction side drain plug and installing this SVRS in its place. All of our valves are designed for use on 0.5 to 10.0 horsepower pumps for small and large water recreational installations including hot tubs, spas, fountains, wading...

In December 2007 the Virginia Graeme Baker Pool & Spa Safety Act was signed, mandating that, in addition to an approved drain cover, all single main drain public swimming pools and spas must have a secondary protective device such as an automatic pump shut-off system installed.The Solution:Use the Emotron PSP20 as a simple, cost effective secondary shut-off device to prevent swimming pool and spa entrapment. Using the existing pump motor as a sensor, the PSP20 will reliably detect a swimmer...

The Vac-Alert 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...

Stingl Safety Vacuum Release System SR-500The Model SR-500 is a Safety Vacuum Release System (SVRS) which works by monitoring the vacuum on the suction side of the pool or spa pump. When a blockage occurs in the main drain or skimmer a sudden rise in vacuum will cause the SR-500 to shut down pump operation and activate an audible alarm (optional). The pump will remain off with the alarm sounding until manually reset. The Stingl SR-500 monitors vacuum 128 times per second and provides rapid...
