Vacless Safety Vacuum Release Systems not only provide an added layer of protection against suction entrapment, but they also act as a drain winterization device and 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 and residential or commercial pools.
I bought this unit two years ago for an apartment I was servicing. I took the unit out of the box and installed and adjusted it all in under 5 minutes. A few months later, I needed a plug to use while vacuuming. I called the company directly, and it was sent the next day. It's a great product.
