44) Close the ball valve (turn handle perpendicular to the valve), switch the power to off
( )
and
observe the vacuum gauge of the ball valve.
If the vacuum level,
as shown on the ball valve’s
vacuum gauge, starts and continues to drop, the
indication is that the hose to the tank connection
(
20A
) leaks. Replace this hose and repeat the test
to verify that the leak has been repaired. If the
leak continues, examine the area where the check
valve is attached to the push-in fitting, circled in
FIGURE 20
,
for any indication of cracks.
If there are no indications of damage to the
threads of the check valve, replace the push-in
fitting of the vacuum tank (
20A
) that connects to
the 3/8" O.D. hose (the red tank connection is shown in
FIGURE 20
).
If the vacuum level of the ball valve’s vacuum gauge holds steady and does not drop, the
indication is that this hose does not leak. Leave this hose attached (since it was confirmed
to not leak) and attach the other tank hose to the other barb of the Y-fitting.
45) Repeat the test with both hoses attached, using the criteria above, to determine whether there
are any problems with the last connected, unverified hose.
46) Once it has been verified that there are no longer any leaks present in the section between
the pump and check valves, proceed to System Confirmation.
