How do Zurn-Wilkins backflow test kits work?

A Zurn backflow preventer test kit is designed to test the operation of the pressure differential relief valve for a variety of backflow preventer models. When testing the system, the model TG-5 requires that the differential pressure relief valve must operate to maintain the zone between the two check valves at least 2 psi less than the supply pressure.

What is a reduced pressure zone backflow preventer?

Reduced pressure zone assemblies (RPZ), also known as reduced pressure principle assemblies, are the industry standard for any type of commercial property. This includes apartment buildings and condominiums. They are the standard because RPZ backflows provide the highest level of protection against pollutants and toxins. Sprinkler Warehouse stocks a large selection of RPZ backflow preventers that are available online and in-store.
