Recommended Testing - Pressure Vacuum Breakers

1. Close Shut-off #2.
2. Close Shut-off #1. If the air inlet valve opens, shut-off valve #2 is leaking and must be repaired before testing can be completed. (Record this on the test report under “Shut-off #2.”)
3. Open Test Cock #1. If water drains from the test cock and the vent opens, the check valve is leaking. If water drains but the vent does not open, shut-off valve #1 is leaking. Repairs must be made before completing the test. (Record this on the test report under “Shut-off #1.”)
4. Close Test Cock #1.
5. Open Shut-off Valve #1.
6. Close all valves on the test kit.
7. Attach high-pressure hose to Test Cock #1.
8. Open Test Cock #1. Gauge should read 15 PSID or higher.
9. Close Shut-off Valve #1.
10. Open Test Cock #2. Gauge should drop to no lower than 1 PSID. If lower, the check valve is reported “Leaking.” (Record this on the test report under “Check Valve Held At.”)
11. Close Test Cock #2.
12. Close Test Cock #1 and remove high-pressure hose.
13. Attach high-pressure hose to Test Cock #2.
14. Open Shut-off Valve #1.
15. Open Test Cock #2.
16. Bleed air from tester.
17. Close Shut-off Valve #1.
18. Slowly bleed down the pressure. The air vent must open at 1 PSID or higher. (Record this on the test report under “Air Vent Opened At.”)
