Do I have a faulty non-return washer valve or isn't there one fitted? It takes a few seconds for the screenwash to start spraying on the windscreen and sometimes the wipers have already started moving by the time it gets going. Makes it even more annoying at this time of year when I just want a quick squirt on the windscreen and a single wipe to clear the road grime.
Is it just me? Has anyone fitted a non return valve in their screenwash pipework?
-
Can't talk for the golf as I haven't had a look but most vehicles have a valve of some description fitted inline with the washer pipework to maintain water in the lines up to the jets. It sounds like yours is leaking back so I would agree that if fitted the check valve is defective. Usually have dirt wedged under the ball. Other possibilities is a blocked jet, a leaky line or at a worst case the washer pump itself.

I would expect some sort of non-return valve to be fitted - would be interested to hear of experiences of other members with the same car if their washers start spraying as soon as the stalk is flicked.

yes, I start spraying as soon as I flick my stalk
(stop sniggering at the back :whistle:)

I prefer no return valve in this weather as the nozzles tend not to freeze when you need them most. So a delay before squirting is not a bad thing.
-
You have heated nozzles - they come as part of the standard 'Winter pack" that all performance Golf have.
-
i've tried mine and they have a delay too, but could that not be because the lights get sprayed 1st?
-
You can either have a short delay before spraying which means that the wipers smear crap and abrasive substances all over the screen before the spray gets to it, or have the possibility of the nozzles freezing and not spraying at all.
In theory, if there is no water in the nozzles or the last few inches of piping leading to the nozzles then all of the washer fluid is kept warm within the engine bay.
Having the headlight washers spray copious amounts of washer fluid all over the bonnet and windscreen a fraction of a second before the wipers are activated means that at least a small quantity of water hits the screen before the washer jets activate, but this only happens when the headlights are on.
-
Surely everyone dilutes their washer fluid appropriately which should remove any risk of freezing?
-
Yes exactly - and (as I said earlier) the washer nozzles are heated).....

Not all of them though - older GTI's don't have them. Just to avoid confusion for us 7.0 owners lol.

Unless you ordered the winter pack... the run out of the Mk7 had a "free" winter pack didn't it? As does the 7.5.
Maybe it might stop the "prolapse" of the headlight washers when its freezing ;-)

Not sure about the runout models - my 2014 doesn't. I didn't tick the box as I ordered leather and it was an expensive option for just the heated washer jets (even though it was a cheaper option if you ordered leather)

Oops I stand corrected! Yes the early 7.0's didnt have it....

mine's a 63 plate which I thought was early. has the heated seats so assume that's the winter pack

Heated seats don’t necessarily mean you’ve got the winter pack. If you’ve got leather seats, the leather option included heated seats. If you’ve got cloth seats and they’re heated then yes, you’ll have the winter pack.
