Check valves? In the washer fluid lines? I did not know we had any, and I'll be darned if I can figure out why we would...

they stop the fluid from draining back into the tank. ie less time for the spray to start.

i'm sure mine had them.

one on both branch after the tee

As far as I know they do not. The tank is not that far away from the washers so it would only take a few seconds to get back to the washers.

Huh... I would say that it is not necessary. I replaced both of my lines and did not install a check valve. Still works fine. Good luck on your search though...

From the diagram, it looks like it only keeps the driver's washer from draining. The passenger's line can drain through the tee and back to the pump, so you've still got a pretty significant delay. Strange....
