Window washer setup/hoses

Alright so I've found out that my motor works for the window washer when I disconnect the hoses, but when I put them all back together again nothing comes out. Is there somewhere that I could get some replacement hose because I think the one I have has gotten plugged with something. Has anyone else had this problem?

I have had this problem. There is some kind of check valve inline before the hose splits in two. Located near the driver side fender in what I recall. I removed the ball in the valve and got very pleasing results.

So yesterday I removed the ball and tested out the spray and got about 4 inches of distance. Then I put the ball back in and got the same amount of distance. Do you have any other suggestions for me to try out? I even cleaned out the nozzle tips in case they were plugged which they were but it didn't change the amount of spray.
