Test Procedure for Spill Resistant Vacuum Breaker Note: For both of the following tests the test kit must be held at the same level as assembly being tested. A. Before starting test, all needle valves and bleed valves on test kit must be closed. B. Flush test cocks before test. Bleed Valve A Bleed Valve B Test No. 1 and 2 008QT shown Test No. 1 - Differential Test Test No. 2 - Air Inlet - Vent Opening Requirement: Differential pressure across check must be 1.
