Water tightness check
It is recommended to verify that the fitting is
water tight:
(a) Remove the water tightness test valve cap.
(b) Fill up the fitting with compressed air (test
pressure = 140 kPa or 20 psi).
(c) Put the fitting in water, wait 3 minutes and
check if air bubbles leave the fitting.
If that is the case, the fitting is not water
tight. Disassemble the fitting once again to
check/clean all contact surfaces and check
gaskets. Replace if necessary.
