Fixing Air Leaks
Air leaks will cause low air output and
increase the time the compressor must
run.
To find air leaks:
1.
Turn the compressor
OFF
when the
tank is fully pressurized and unplug the
compressor.
2.
Listen for the sound of air to find fittings
that may be leaking.
3.
Spray the suspected air leak with a
soap and water solution. If you see air
bubbles, you have found your leak.
To fix air leaking around fitting threads:
1. Unplug the air compressor and drain
all the air from the tank.
2.
Unscrew the fitting that is leaking. Clean
and wrap teflon tape and/or spread pipe
dope on the threads.
3.
Re-install the fitting to the compressor.
To fix air leaking through a valve:
1. Unplug the air compressor and drain
all the air from the tank.
2.
Remove the valve, clean it thoroughly,
then re-install with teflon tape and/or
pipe dope.
3.
If the valve continues to leak, replace it
with a new valve.

Check valve diaphragm and
spring.
Diaphragm
O-ring
3.
Inspect the O-ring and diaphragm
(
Figure 14
) for damage and dirt.
4.
Replace any damaged parts and clean
any dirt off of the diaphragm and O-
ring.
5.
Re-assemble the check valve. Make
sure the diaphragm presses squarely
against the air supply tube opening.
