If the squirter check valve is unidirectional, should I be able to blow air from one end ?

The check valve should have a directional arrow molded on it, so you know the direction in which to install it.
Because it is a spring-loaded valve, you may not be able to generate enough pressure by just blowing in it. If you have a hand pump, you should be able to test it -- it should only take a few psi to open. Or, if you have a vacuum pump, attach it to the outlet and try drawing a vacuum. |
