quickly.
Control unit leaks compressed air.
Regulators do not adjust to the same level.

1. Water Off.
2. Defective or plugged Regulator.
3. Regulator plumbed backwards.
1. Stand Tube Cap plugged (not venting).
2. Air line to Regulator pinched.
1. Regulator seat worn.
2. Stand Tube Cap plugged.
3. Air Loading Unit putting out too high pressure (defective solenoid).
1. Shut off or pinch off all lines going to the individual controls to find
which house is the problem.
2. Open one line at a time until you find one that causes the compressor
tank to lose air more quickly.
3. See correction for house leak below.
1. Shut off the incoming line to the control and watch the small
INCOMING PRESSURE GAUGE. If the control holds pressure, the
leak is between the air source and that house.
2. With the incoming air off and the gauge indicates that there is a 2
PSI drop or more within 1 minute, the problem is in the control, lines,
or regulators.
3. Shut off or pinch off all lines going out to the regulators and the
incoming line. If the control loses pressure, the problem is inside the
control. See control unit leak below.
4. If the unit holds pressure, release one line at a time to isolate the
cause of the leak.
5. Test line connections and regulator for leaks.
1. Check the vent hole in the red cover of the Air Loading Unit, see
figure 1. Put soapy water over the hole. A small amount of air coming
out is normal (bubble should grow slowly over several seconds).
2. Put soapy water on all internal hose connections to find leak.
Water in some of the air lines. Drain hose and check for defective
Regulator Diaphragm. This is done by pinching the hose off at the
nipple line regulator and if there is no leak the water column will
remain constant, if the regulator has a leak the water column will
decrease.
