Hey everyone, I know there's been a couple of threads on this kind of thing already, but I couldn't find one with a solution to my problem.

Basically I've been having a bit of a problem with the screen washers leaking and emptying over the course of about 2-3hours or so. I had a look in the bonnet and found the grey one-way valve near the bottle was leaking through the hole in the bottom, and it was spurting out of there when the jet was activated. So one trip to halfords later I bought one of their own brand one-way valves and stuck that on. Now the front washers are working fine, and there doesn't seem to be a leak, but the rear washer doesn't work. (A little bit of water comes out but not enough to get to the windscreen). Is this something else or a related problem?

Hello mate and WELCOME TO THE FORUM!!

Check that you have pinched the hose when replacing the 1 way valve for the fronts. Its very easily done. Failing that, you can disconnect the rear washer hose at the pump and then activate the pump to check that its working correctly.

Hope that helps,
Alan

thanks very much, I'll have a look at that later!
