When this happens and your air compressor is working properly you will hear air release from the pressure relief valve for 3 to 5 seconds and slowly stop.
When the air continues to leak from the pressure relief valve then you will need to look at the one way check valve that is in you air compressor tank
The Check Valve allows pressure to go from your air compressor pump directly into the air compressor tank. When this valve is operating properly the air can only go into the tank and is then prevented from coming back out of the tank by the One Way Check valve.
