b. Quarterly Main Drain Test
1. Notify the Authority Having Jurisdiction and those in the area affected by the test.
2. Record pressure reading from the water supply pressure gauge (B.12).
3. Verify that the outlet chamber of the deluge valve is free of water. No water should flow from the drip check (B.7) when the plunger
is pushed.
4. Fully OPEN the flow test valve (B.11).
5. When a full flow is developed from the flow test valve (B.11), record the residual pressure from the water supply pressure gauge
(B.12).
6. When the test is complete, SLOWLY CLOSE the flow test valve (B.11).
7. Compare test results with previous flow information. If deterioration of the water supply is detected, take appropriate steps to
restore adequate water supply.
8. Verify:
a. Normal water supply pressure has been restored to the inlet chamber, the priming chamber, and the release system. The
pressure on the priming chamber water pressure gauge should equal the system water supply pressure.
b. All alarm devices, and valves are secured in normal** operating position.
9. Notify the Authority Having Jurisdiction that the test is complete. Record and/or provide notification of test results as required by
the Authority Having Jurisdiction.
** For normal operating position, refer to Figure 1 and/or Trim Charts and System Data for the system used.

1. Notify the Authority Having Jurisdiction and those in the area affected by the test.
2. Fully open the flow test valve (B.11) to flush away any accumulation of foreign material.
3. Close the flow test valve (B.11).
4. Trip the system by operating the release system. Allow a full flow to pass through the deluge valve. Water flow alarms should
operate.
5. When test is complete:
a. Close the main water supply control valve (D.1).
b. Close the priming valve (B.1).
c. Open the auxiliary drain valve (B.13).
d. Open all system main drains and auxiliary drains. Allow the system to drain completely.
6. Perform SEMI-ANNUAL maintenance. Refer to paragraph 6.III.B SEMI-ANNUAL MAINTENANCE.
7. Place the system in service. Refer to Item 4.B, INSTALLATION: PLACING THE VALVE IN SERVICE.

A. After Each operation:
1. Sprinkler systems that have been subjected to a fire must be returned to service as soon as possible. The entire system must be
inspected for damage, and repaired or replaced as necessary.
2. Deluge Valves and trim that have been subjected to brackish water, salt water, foam, foam/water solution, or any other corrosive
water supply should be flushed with good quality fresh water before being returned to service.
3. Perform SEMI-ANNUAL maintenance after every operation.
