External Leak Test
After first stage reassembly and final adjustment of the second
stage has been completed, submerge the entire regulator in a test
tank of clean water while pressurized with 2,500-3000 psi. Observe
any bubbles arising from the submerged regulator over a one minute
period. The recommended time is necessary due to slower bubble
formation that occurs in smaller leaks. Disassemble the regulator at
the source of the leak to check sealing surfaces, assembly sequence
and component positioning in order to correct the problem(s).
NOTE : The location of extremely small leaks can best be
detected by applying a soap solution to the leak area. Before
disassembling to correct any leaks, rinse the entire regulator
thoroughly with fresh water and blow out all residual moisture
with filtered, low-pressure (25 psi) test gas. Refer to the
Troubleshooting section.

When the second stage has been adjusted and tested accord-
ing to the prescribed procedures, close the cylinder valve com-
pletely, and purge the second stage to depressurize the sys-
tem. Loosen the yoke screw to remove the first stage from the
cylinder, and seal the dust cap over the inlet fitting. Disinfect
the mouthpiece, and dry the regulator completely with a clean
towel. This completes the overhaul service procedures for the
SeaAir regulator.
