When I brake hard or park facing down hill, all of my screen wash drains out if my bonnet jets.

It is a slicktop so the reservoir is in the boot.

 

Any ideas?

Sorry :lol::lol:

I think they are fitted with none return valves, Maybe stuck open?

Do they spray strait away or do they have to build up pressure first?

They don't spray, just drain. But at a really steady flow.

Where are the non returns?

Pretty sure he means when you use them mate. lol

Oh, sorry.

Does sound like your non return valve has failed. You can get them from halfords for a couple of quid. Just cut the line under the bonnet and put the valve on. That should sort it for you :)

Ta. I didn't think they had non returns on them. But I suppose it makes sense.
