with test procedures recommended by ASSE, AWWA, CSA, FCCC, HR-USV, and
NEWWA. The BTK2 is comprised of three valves and is specially designed for testing
TEST EQUIPMENT
backflow prevention assemblies. The tests can be completed in almost any area by mounting
the unit with the included high performance elastic cord. PTFE-lined brass ball valves
simplify the adjustment procedure. The large, easy-to-grip needle valve allows for quick
adjustment. The kit includes a 4.5˝ diameter diaphragm differential pressure gage (0 to 15
psid), a 1.5˝ diameter in-line pressure gage (0 to 200 psig), three 3´long hoses (colorcoded), three sets of brass adapter fittings for hookups to all standard size test cocks, an
elastic cord for hanging/mounting, and a durable polyethylene carrying case.
