Air receiver loses pressure:
1. Check for system leaks through pipes, fittings and
seals.
2. Inspect the check valve to see if it is allowing air
pressure to leak back into unit.
3. Pressure pumps will have bubbles around head
assembly during operation. Stop operating the
pump for a few minutes and check for air leaks at
pump.
4. Vacuum systems should have the check valve
removed and inspected for dirt buildup. It may be
necessary to need an AV460 filter installed prior to
tank to eliminate contaminants.
A leak is located at the unit:
1. Vent all pressure from inside the air receiver until
gauge reads 0 PSI.
2. Inspect check valve for dirt buildup, wear and proper
operation.
3. Replace check valve if necessary.
