Test Results
The resultant closing pressure may be compared to the
table below.
Note: Variations in the manometer closing pressure test
result are possible based upon the test conditions and
the test method utilized.
Valve Setting
206521-001-G-INS.indd 22
Note: For valves with distal catheter and/or
SIPHONGUARD Device, an extended test time
is recommended in order to compensate for the
possibility of a decreased flow rate due to the
additional catheter resistance and/or SIPHONGUARD
Device activation. Allow the water column to drop for
4 minutes and then read the resultant pressure.
