Response to Yup. Cuz' what holds the checkvalve open isn't the pressure...

They design for longevity rather than efficiency.

Your light spring is a good mod but the heavy spring and the force it exerts to the sealing process stands a better chance against particles of debris which so often collect across the seal surface in question. Where the first pumpstroke might otherwise fail to seal completly should the spring be of minimal force.
