Field Test Procedure
(RP) ASSEMBLIES Using 5-Valve Test Kit

Flush Test Cocks (TC)

1. Close #2 Ball Valve on Backflow.
2. Install Test adapter (90-micron filler equipped preferred).
3. Open TC #4, let trickle.
4. Open TC#2, then close.
5. Open TC #3, then close.
6. Close TC #4.

Attach Test Kit

1. Close Hi, Lo and bypass valves and Hi and Lo bleed valves on test kit.
2. Attach High hose to TC #2, Low hose to TC#3 AND Bypass Hose to TC#4.
3. Open TC#2.
4. Open High bleed valve; bleed air, close High bleed valve.
5. Open TC #3.
6. Open Low bleed valves; bleed air, close Low bleed valve.
7. Open High Valve for duration of the test.
8. Open Bypass Valve.
9. Loosen Bypass hose at TC #4; bleed air, tighten.
10. Slowly open Low bleed valve until needle on test kit pegs to 15 PSI then close.
    Test Results: If the differential gauge reading remains steady, record #2 shut off valve as tight.

#1 Check Differential

1. Close Bypass valve.
2. Open TC#2 and TC#3.
3. Open High bleed Valve.
4. Open Low bleed Valve.
5. Close High and Close Low bleed Valve (in this order).
   Test Results: Record the pressure differential across #1 check valve. If the differential reading is 5 PSID or greater, record the number and mark check valve #1 as tight.

Relief Valve Test

1. Slowly open Low Valve, when relief valve first drips, record this number.
   Test Results: The relief valve must read 2 psid or greater. If the reading is 2 psid or higher, make certain the buffer between #1 check valve and relief valve is 3 psid or greater for backflow to pass.

#2 Check Differential

1. Attach High Hose to TC#3.
2. Attach Low hose to TC#4.
3. Open TC#3, Open TC#4.
4. Open Hi bleed, Open Lo Bleed.
5. Close Hi bleed, Close Lo Bleed.
   Test Results: Record pressure differential across #2 check valve. If the differential reading is 1 PSID or greater record the reading and mark check valve #2 as tight.

Restore System

1. Close all TC’s
2. Remove hoses.
3. Open all valves on the test kit to drain water.
4. Restore #2 shutoff valve to pretest state.

The tester shall provide copies of the test results to the owner and other appropriate parties as required. The tester shall maintain a copy for his or her records.
