Check Valve CV221502SJ

This is a high-quality OEM replacement part which is designed for use with Campbell Hausfeld air compressors. Check valve lets the pressurized air flow into the tank and prevents it from flowing back into the pump. Unfortunately, over time it may wear out or even get damaged eventually requiring a replacement to ensure your equipment functions properly. When the check valve is faulty, the compressor will initially function normally until the tank fills with air. At that point, the pump will attempt to restart, but the engine will produce only a humming noise. Similarly, if the tank is already full of air, the engine will produce only the humming noise without actually engaging. When replacing this part make sure to unplug the air compressor and release the air from the tank. It is a metal check valve and is sold individually. You would need a wrench set to disconnect and reconnect lines an perform the repair.
