MOUTHPIECE TEST
In closed circuit mode, cover the right (exhale) side and the LP hose inlet, and blow (gently!!) into the mouthpiece. The
mushroom valve should seal and no gas should exit out of the second stage port or the front switch plate.
Problems:

Mushroom valve on the le could leak. Remove the carrier and inspect it again.

2nd stage port leak. Remove the inner barrel and inspect/replace the 2 side port O‐rings.

Front switch plate leak. Remove the inner barrel and inspect/replace the 2 barrel end O‐rings.
In closed circuit mode, cover the le (inhale) side and the LP hose inlet, and suck (gently!!) into the mouthpiece.
Problems:

Mushroom valve on the right could leak. Remove the carrier and inspect it again.

2nd stage port leak. Remove the inner barrel and inspect/replace the 2 side port O‐rings.

Front switch plate leak. Remove the inner barrel and inspect/replace the 2 barrel end O‐rings.
Other leaks. Cover both the inhale and exhale sides of the mouthpiece, as well as the LP hose inlet to the 2nd stage,
while gently blowing into the mouthpiece. Also do this test while gently sucking from the mouthpiece. These tests will
determine if the rubber mouthpiece has a leak or if the 2nd stage regulator a fault. The 2nd stage adapter O‐ring could
also be causing a leak.
CLEAN AND INSPECT THE MOUTHPIECE AND SECOND STAGE AS REQUIRED. SERVICING OF THE SECOND STAGE
SHOULD BE DONE BY A QUALIFIED SERVICE TECH.
