Tourer rear screen wash
 

My rear screen wash doesn't spray water although the pump can be heard running. Does anyone know where I can find a line diagram of the system please?
Cheers

Does the front one spray OK?

If not you will have a blocked filter in the washer bottle, if the front sprays ok, chances are the pipe is kinked where it enters the rear bodyshell from the tailgate.

Thanks for that. The front is fine. I'll check for a kink where the pipe goes to the tailgate although it's still got the protective concertina tube over it. Someone has suggested that it may be a non-return valve in the pipework that's not opening?
Thanks again

Pull out a wire brush bristle and rod the jet out,it could just be blocked with road dirt :}

We've tried that thanks. We're toying with pumping it through with a cycle pump (very carefully) as that is positive displacement as opposed to the little electric pump installed which will be a centrifugal type.
