Question Rear washer check valve location?

Anyone know where the check valve is located on the tubing which serves the rear screen wash? Mine takes ages for the water to emerge at the rear screen - I suspect the check valve is letting the fluid to drain back to the reservoir between usages.

Thanks again plain OM. Your input to this forum is, as far as I am concerned invaluable. I'll update when I get in to it and find the villain.

Mine did the same thing. Look for a puddle that appears by drivers front tire when you activate the pump. There are 2 pumps in the washer tank, 1 for rear and 1 for windshield feeding seperate lines. The hoses dry out and crack over time. I replaced the rear hose yesterday, front I did last year. Only a 3 foot section from the pump to above the wheel arch was needed in both cases.

RIP 96 Legacy 2.2 Thanks for 380,000 miles. (4EAT lost reverse)

Cheers, but my issue is different in that the water eventually gets to the rear screen. There's no question in my mind that the piping front to back drains back to the reservoir between usage, so I don't see any pipe leaks evidence.
