is the spray pattern adjustable on these as i would like the mist to hit a bit higher on the windscreen.
Pidu
No, they are not adjustable. If you put a drop of a glue at the bottom of the nozzle it will do the job.

Even at motorway speed mist reaches top of the windscreen.

Blooming good idea.
So simple yet so clever.
Give that man a coconut. :D
Pidu
If you find this idea useful better send me a beer, pm me for delivery address :lol:
salsheikh
mmm, will give it a try and report back.
Pidu
It will also help to reduce washer fluid marks on the bonnet, but the best thing to do is to use 2 non-return valves. I was sick of cleaning the bonnet, now I have no marks at all.

If you can show me the non return valves and where you got them then it's probably worth a beer. :)

I used original Vauxhall non-return valves from Vectra B:

They are cheaper on ebay, good quality, can recommend. There are also some cheaper fiat valves or universal ones, but they are not that good and some of them restrict too much the flow of fluid.

Pop up the bonnet, remove the mat.

Take washer tube off the jet and connect the valve. Remember about the direction of flow, it is marked on the valve. Use piece of tube to connect valve with jet. Two valves give best result - one in front of each jet.

Photos by Czari. Used fiat panda non-return valves.

You do exactly the same in case of heated jets.

If we are talking about it it is worth to say about third non-return valve - at the back of the car for rear window jet. If you fit it washer fluid starts flowing immediately, not like without the valve - after few seconds, when rear wiper is making second run.

To fit it open the tailgate, at the top you will see rubber seal with washer tube running through it, remove it, cut the tube somewhere between rear jet and the seal and connect the valve. Put the valve inside the tailgate, fit the seal - job done.

I can make some photos tomorrow, it's too late and too dark today :P

Dose the one way valve just allow extra pressure to build up so that the washer fluid squirts a little further stopping it from dribbling all over the bonnet?
Pidu
Marks on the bonnet are caused by washer fluid dribbling out of the jets after you have used them. There is some amount of washer fluid in the tubes and while car is moving it is getting out. Non-return valves do not increase the pressure, they require higher pressure to let the fluid flow, so it happens only when washer pump is working. If pressure drops fluid will not flow any more, so you have no marks on the bonnet. Non-return valves also do not allow the washer fluid to move back to washer fluid container as they don't let air get into the tubes, when pump is not working fluid is still in the tube ready to flow immediately when pressure increases. Funny thing is Ford put one non return valve in the washer system, but as you can see it is not quite working as it should and we have those nasty marks to clean every time. There might remain some small triangle shaped marks on the bonnet in the area between jets and windshield - that is understood, but it looks like drop of glue can help, for some time I have no washer fluid marks to clean.

Hi

Are these mist washer jets different from the standard ones on a focus? , never heard of them before.
Pidu
This is cheap and easy upgrade. They are from Focus Mk3.

Mist jets in action at different speeds (speed in kmh, not mph)

If anyone wants non return valves, you can get them from any pet supplies shop as they are used for fish tanks. :)

My friend used that kind of valves, but they were no good - fluid pressure decreased too much. As there is many types of fish tank valves it might be the matter of luck. I prefer to use well tested genuine automotive parts in my car ;)
alkyz89
also fish tank valves are used to pass air through and to stop the return of water in the case of a fault on an air pump...so i dont know how they would handle with the constant fluid being passed through the valve... may have no difference what so ever but its worth a thought...
+1 to pidu i think id prefer something designed for cars

Could somebody post a link to the hose they used to connect the non return valves to the jet, i bought 4mm dia stuff off ebay but it seems to loose a connection, so i figured someone on here could give us a nudge in the right direction,

Ta very much,

I was looking at quotes recently, one dealership came back and said that a pair of mist and heated jets was just under £22.00 think the valves were about a fiver.

Which dealer?  The heated ones used to be something stupid like £4 each, but I can't find them for less than £25 the pair now :(

Ford Retail Limited: part number 1423953 - £21.19.

 

He does state the price of the "washer jet" and not "jet's" so I hope thats a pair!!!
