Test Check Valve No. 1
1. Ensure shutoff No. 1 is open and shutoff No. 2 is closed.
2. Connect the high side hose to test cock No. 3, and the low side to test
cock No. 2, and open both test cock No. 2 and test cock No. 3.
3. Open valve C, then open A to bleed air from the high side. Close valve
A, then open B to bleed low side. Close valve B.
4. Connect the vent hose loosely to test cock No. 1. Open valve A to vent
air from the vent hose. Tighten the vent hose at test cock No. 1, and
open test cock No. 1.
5. Close shutoff No. 1. Slowly loosen the hose at test cock No. 2 until the
differential gauge rises to 2psi then retighten the hose. If the differential
reading does not decrease, record the check valves as "tight."
Test Check Valve No. 2
1. Move the high side hose to test cock No. 4, the low side to test cock
No. 3, and open both test cock No. 3 and test cock No. 4. Remove
the vent hose from test cock No. 1, and open shutoff No. 1.
2. Open valve C, then open valve A to bleed air from the high side. Close
valve A, then open valve B to bleed the low side. Close valve B.
3. Connect the vent hose loosely to test cock No. 1. Open valve A to vent
air from the vent hose. Tighten the vent hose at test cock No. 1, and
open test cock No. 1.
4. Close shutoff No. 1, then slowly loosen the hose at test cock No. 3
until the differential gauge rises to 2psi and retighten the hose. If the dif-
ferential reading does not decrease, record the check as tight. Remove
all the hoses and restore the valve to original working condition.
NOTICE
The assembly will fail both the first and second check valve tests
above, if shutoff No. 2 leaks excessively. To test for a leaky No. 2
shutoff, use the following procedure.
Test for Leaky No. 2 Shutoff
1. Connect the high side to test cock No. 1, and the low side to test cock
No. 4. Open test cock No. 1 and test cock No. 4. Close shutoffs No. 1
and No. 2.
2. Close valve C. Open valve A, next open valve B 1⁄2 turn, then loosen
the hose at test cock No. 4 to remove air. Retighten the hose.
3. If the differential gauge rises above 0 (zero), there is excessive leakage
at shutoff No. 2. The shutoff must be replaced to test the assembly.
