Locating the check valve - Craftsman 919.152930

by Bill McWhorter

Leaking from the unloader valve constantly. I am assuming the check valve needs cleaned or replaced. My model has a manifold under the pressure switch. I have seen some drawings for this model show a typical check valve buried in the manifold and others don't show one. The parts drawings that came with the unit years ago are for a similar but different model. Any ideas?


Also the pin in the unloader valve does not seem to make contact with the tang on the pressure switch. May be just because there is no air in the tank at this time.

Thanks!

If you Google "image Craftsman 919.152930" as I just did, you should find a number of sites that offer parts for this model.

One of the sites has a diagram of the pump parts, and if you scroll down, you will find the fitting for the tank check valve.

As to this "Also the pin in the unloader valve does not seem to make contact with the tang on the pressure switch. May be just because there is no air in the tank at this time. " Yes, I agree.
