Replaced the leaking screen washer pump. Hoped it would solve poor pressure issue I had.
Now have no leak, but no pressure to jets either, just dribbles of water onto bonnet with occasional jet hitting bottom of screen.
Filter in bottle was very clean, no gunk at all. Used a pin on jets, no change. Pulled tube off pump and switched on, squirted half a tank into the bumper, seems to be plenty of pressure there.
Blocked tubing somewhere? Passenger side was always more powerful than driver side. Now passenger side just dribbles better than the driver side...
Typical that I have the problem just before MoT due...
Hopefully I'll have another dry day tomorrow to do more testing.
