That should confirm weather the missing check valve is the problem. What are the advantages of using a spring check valve instead of a regular check valve?

A regular check valve uses back pressure to close it. Your pressure will be equalized once the pump is off, allowing it to fall open. A spring check will close when the pump turns off and stay closed __________________ You can have it good, fast or cheap. Pick two.
