This is a view of the o-ring assembly, piston lock nut and the plate attached to the end of the piston. The quarter inch holes that let water in as the piston pushes to the right are seen as well. The brass barb fitting is the piston air exhaust.
We're using a Humphrey solenoid pneumatic valve (model 310) to control the air piston.
