EXHAUST VALVES
2. Make sure exhaust valves are closed. 3. Verify that the pressure gauge in the rear void reads 80 psi or higher. If the gauge does not read a pressure, move the ball valve to the service position and listen for exhausting air. If no air is exhausted from the system, there is no air in the rear 45 gallon tank. This indicates that the pressure protection valve could be bad.
