I bought a used 11x14 Nova single slot archival print washer (cheap) off of Ebay. Having never used a vertical print washer before, I'm at a loss as to how to use it. It has a rubber hose (inlet) at the bottom of one end, and a hole at the opposite bottom end. It also has a large exit (?) tube at the top, on the inlet side. When I turn the water on, most of the water goes right through and out the other hole without it going up very high. Should there be some sort of cork or stopper there? I assume that the water flow would come in the bottom inlet, rise up, and finally pour out the exit tube at the top. This doesn't happen now. Any help would be appreciated! -Chase M.
