Especially at this time of year, roads are mucky with salt spray, wipers going for most of any journey, windscreen rapidly gaining that greying muck all over it. Ah ha! But I have squirty water available! Pull on the stick and oh… two whole dry wipes before the magic blue/yellow (other flavours are available) soapy juice comes through. Two wipes of near total blindness.
Not two minutes later a truck sprays you with more muck, ah ha! More squirty water needed! Another pull on the stick, two more blinding dry wipes before the magic happens.
The rear is also getting quite opaque, best have a wash. Push the button, wait, wait, dry wipe after dry wipe, and suddenly clean as the magic fluid reaches the nozzle.
What’s going on? It didn’t do this at first. A recent development over the last few weeks. I’ve just been out (in the blizzard) and had the bonnet liner off. All that pipework is sound, NRVs I can breathe through both ways but they may be fluid switch and not air so unknown, and all 3 at the same time? I have my doubts. My headlight washers also never seem to spray but this maybe needs more testing, and being xenons I want to be considerate to other road users, as headlights are a 24hr necessity from now until April in my local area.
So I’m leaning towards bottle/pump/filter. I am not going to be tackling this in the snow, so maybe at the weekend. Maybe the filter is clogged and flexing, creating negative pressure between it and the pump, then after the scoosh, it’s drawing back down and taking the juice out of the lines?
Happy to take any other rambling thoughts and fix suggestions, or maybe this is simply another wonderful “feature” of the vehicle. (I don’t love it any less, my timed climate has been defrosting it for the school run all week, nothing beats bashing down a deep snowy lane in a warm car).

Was happening in the summer-like period of November too, temperature in the teens, in November!! And I would hope my -20 screenwash isn’t freezing at a paltry -2. D4 XS Commercial - MY16 - Corris Grey

I'm guessing but there's probably a 'one-way' valve in the system somewhere that used to do it's job and stop fluid draining back out of the pipes into the tank but it's now sticking open! Disco 4 Landmark
