I know they are not cheap, but genuine and high quality.

Thanks very much Peter!

FOCA, sorry mate, but it looks like you did not read the whole thread and linked thread (post #4). Do it first please. It works, for me and many other Focus users from different countries. I found this solution on other forum and shared here.

BTW Focus has one factory fitted non-return valve too.

Ahh - the thread makes more sense now -

The cars already have 1 non-return valve (that does not work that well) and you add 2 (1 per nozzle)

Now i would like heated nozzles with adjustable aim fine mist nozzles with multiple jets - that would be good

i have them one mine and somehow i still get the dreaded dribbles. i must have done something wrong

[jon-v8]

That's interesting - I was just about order the valves, and now reading you're still getting the excess screen wash running out?

From what Peter has said, he hasn't had an issue at all??

Hmmm I'm in a dilemma now too lol

[FOCA]

i have them one mine and somehow i still get the dreaded dribbles. i must have done something wrong

Mine is still standard, but when i read this thread i thought the screenwash system already has non return valves (or a non return valve) fitted (to stop the screenwash fluid draining back to the bottle/ resovoir and the lines filling with air )


So i thought, if the system already has non return valve(s) fitted, how can fitting more help unless its restricting the flow of water/ reducing the amout of spray going onto the windscreen

Perhaps its more to do with the exact design of the nozzles, jets etc, the pressure generated by the pump, etc

Im going to give it a try myself (more out of scientific curiosity) personally im not really that bothered by water on my bonnet, im just happy when the car starts, runs, gets me where i want to ho, and how quick it is, everything else is a bonus (and i hardly ever clean it!)

guys, eter hasnt had a problem, i think i might have not fitted mine correctly.
i fitted mine but there is a bit of a length from the jet and the valve, i dont think there should be.

The whole problem is strange, focus is my first car with this issue. And unlike FOCA said it is not only water on the bonnet, those marks were hard to get rid off, normal washing was not enough.

The way I see it Ford did not design washing system correctly, like many other things. Yes, there is a non return valve to keep the fluid inside tubes and prevent it from going back to the tank and actually this together with diameter of tubes and angle of the nozzles may be causing the problem. Tubes are about 5mm, while my previous cars were using 3mm tubes as far as I remember. When we use washers we are left with tubes full of washing fluid. While driving car is shaking and air slowly gets inside tubes from the nozzle side, obviously it pushes washing fluid out. Air must be getting pretty far, as nozzles dribble for a long time causing marks on the bonnet. I believe it happens due to "large" diameter of tubes. For the same reason Ford had to use non return valve as larger tubes require more time to fill, without valve it would take more time from pressing button to spraying from the jets and in some situations wiper would be moving on dry dirty windscreen causing scratches.

When we fit non-return valve close to the nozzle there is only about 1 cm of tube filled with washing fluid. Even IF it will dribble it will be a very small amount of fluid.

Other thing is I have used 3mm tube to connect non-return valve with nozzle, the only available in the store on that day. I remember I had to heat it up to fit. It is very short piece, valve and nozzle almost touch each other. The result for me is as written few posts earlier.

Sorry for such a long post, shared few thoughts I had while having a beer

Modifications : - re-designing/ engineering everything Ford never got right.

Peter, can you put up a pic of your return valve/wahser jet?

[Pidu]

Honestly I do not want to remove mat now, little bit to cold for me.

You can find picture in this thread - post #8

You will see piece of blue tube connecting valve and jet. I did it shorter, as short as possible and that is it.

Thanks Peter, mine doesnt look like this, hence mine still leaking. will sort it out soon.

Hi bud just got these through the post just a quick question what end goes where lol
I see an arrow pointing up
Thanks

[Pidu]

Arrow shows direction of fluid flow. It must point towards washer jet.

[Jay Ali]

Thanks a lot
I should've just read your guide, only 2 posts above mine lol silly me
