Common questions:Q: Where is my check valve located?
A: It is found at the end of the pump supply tube where it enters the air tank. 90% of it is located in your tank! This is why the check valve above doesn't look like the one on your unit.
Q Why do check valves fail?
A There is an internal spring that holds a disc closed when the air compressor turns off. When the spring rusts or the disc becomes brittle and cracks, this allows air to back-feed into the pump as well as the small pressure tube Schrader valve.
Q: How do I remove my check valve?
1st Turn off your air compressor.
2nd Drain all of the air pressure from your air compressor tank.
3rd Follow the air supply tube from your pump head and find where it enters your tank. There should be a brass compression nut around the tube which connects to threads protruding from your air tank.
4th Loosen and remove this supply tube from the check valve.
5th Using an appropriately sized socket, remove the check valve from the tank.
6th Now you have removed your rusty and defective check valve causing you all of your problems.
7th Install thread sealant on the new check valve (if sealant is not supplied on the check valve) and carefully thread it into the tank.
8th Tighten the check valve snug, but do not overtighten.
9th Reverse the steps above to complete.
