11.3.A. LEAKAGE
First identify where the leak is coming from- see diagram below.
NORTHSTAR ORION Owner's Manual
Leakage Path 1 (from the core assembly)
This problem can be temporarily overcome by fitting the cap, as
this is a secondary seal. To permanently fix the problem, carry
out the following operations:
With the buoyancy tube deflated and the valve in the closed po-
sition, remove the Cap, then fill the valve with some warm soapy
water. Open the valve by pushing the Spindle down and turning
anti¬clockwise. Allow the water to drain through. Rinse through
with plain water. Re-check the valve for air tightness.
If the leakage persists, use service tool C16605 with the buo-
yancy deflated and unscrew the core of the valve by turning it
anti¬clockwise. Check the rubber seal on the valve core for dirt
or damage. Check that the sealing face on the plastic core is
clean and undamaged.
Refit the valve and tighten as tightly as you can using hand pres-
sure on the tool. Inflate the buoyancy tube and check for air
tightness. We recommend that after around 24 hours the valve
should be retightened to ensure it has fully seated. If the leakage
persists contact your local repair shop.
