Test Check Valve No. 1
Step 1: Ensure shutoff #1 is open, shutoff #2 is closed.
Step 2: Connect high side hose to test cock #3, low side to test cock #2 and
open both test cock #2 and test cock #3.
Step 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.
Step 4: Connect vent hose loosely to test cock #1. Open valve A to vent air from
vent hose. Tighten vent hose at test cock #1, open test cock #1.
Step 5: Close shutoff #1. Slowly loosen hose at test cock #2 until differential
gauge rises to 2psi and retighten hose. If the differential reading does not
decrease, record check valves as “tight”.
Test Check Valve No. 2
Step 1: Move the high side hose to test cock #4, low side to test cock #3 and
open both test cock #3 and test cock #4. Remove vent hose from test
cock #1, open shutoff #1.
Step 2: Open valve C, then open valve A to bleed air from the high side. Close
valve A, then open valve B to bleed low side. Close valve B.
Step 3: Connect vent hose loosely to test cock #1. Open valve A to vent air from
the vent hose. Tighten vent hose at test cock #1, open test cock #1.
Step 4: Close shutoff #1, then slowly loosen hose at test cock #3 until differential
gauge rises to 2psi and retighten hose. If the differential reading does not
decrease, record check as tight. Remove all hoses and restore valve to
original working condition.
NOTICE
The assembly will fail both the first and second check valve tests above, if shutoff
#2 leaks excessively. To test for a leaky #2 shutoff, use the following procedure.
Test for Leaky No. 2 Shutoff
Step 1: Connect the high side to test cock #1, low side to test cock #4. Open
test cock #1 and test cock #4. Close shutoffs #1 and #2.
Step 2: Close valve C. Open valve A, then open valve B

turn, loosen hose at
test cock #4 to remove air. Retighten hose.
Step 3: If the differential gauge rises above 0, there is excessive leakage at
shutoff #2 and it must be replaced to test the assembly.
