Backflow Sight Tube
The SamsonRiser Backflow Test Sight Tube can be used to quickly test all brands of most backflow prevention assemblies, including: double check valve assembly, double-check valve detector assembly, pressure vacuum breakers, spill-resistant pressure vacuum breakers, and single check valve assembly for fire.
This assembly is designed for use according to the American Water Works Association (AWWA) Sight Tube test procedures. Although a ¾” diameter site tube is “recommended”, this ½” site tube was chosen for its lightweight convenience and the results of the test are not affected.
