Trying to wrap my head around the PET illustrations for the windshield washer pump.. There is an illustration for an electric pump which is what I'll be using, however it seems to only call for "T" pieces - but I believe that's being shown with the early chrome nozzles.
Did maybe early nozzles incorporate a check valve, but the later black one didn't? The illustration for the later black nozzles lists a "T" shaped "valve with valve" (probably a separate check valve, no?). Anyone know what's what here? . |

Check valves are one-way valves. Are these really pop-off valves instead? Pop-off would allow spray but not weeping/leaking. I just did my electric pump install but did not include any valves, maybe I need to reconsider. I’m curious why 2 valves instead of 1 valve before they branch to the 2 nozzles.
