I read a good blow through with an airline may cure it, but I haven't got an airline, or know how to do this??? The Rover is due for its MOT and this is an instant fail. If nothing forthcoming I may have to bite the bullet and take it to my garage, which is annoying and probably expensive considering that any garage will charge at least an hour's labour.

Hi Rob.
So we know you have cleaned the bottle out, and the lower little filter, photos so members know what we are talking about
in a pictorial sense.
Wheel arch liner peeled back.
1
Pump pulled out to check the filter and drain oil fluid.
2
Once fluid is low enough remove the little filter.
3
This one had been cut off so water should have been getting to the screen.
4
I replaced it with one that had not be trimmed down.
5
So i know the pump is ok the fluid is/was clean not congealing which can happen if you use two different fluids, keep to one make and type even for topping up, the filter is clean.
Next step remove the bonnet heat & sound cover, to gain access to the washer tubs and spray jets.

Either buy or find your self a bicycle pump, i happen to have a couple, also so a straight connector, and a piece of tubbing 4mm.

In the centre there will be a one way valve with three barbs coming from it, pull the left lower tube off this is feed tube to the valve.
11
Connect the pump/pumps in my case to the tube/tubes.
12
13
Now give the tube a good pumping the feed one will blow back any gunk in the tube towards the bottle & its knowing working pump, you can then pull the tube of the working pump and reverse pump it back up hopefully clearing and blockage if there is/was one.
Do the same to the jets pump hopefully clearing any blockage in the eye of the jet.
Wash out the washer bottle which in your case you have done so already.

15
With the little back in place and the pump inserted fill the bottle with your choice of screen wash, this time of year making sure its for winter not summer screen wash.
16
17
Now check to see if you have any spray going onto the front windscreen, where it should go.
If not then the one way valve is the problem.
18
Replace it with a good working new one, if you do not have one or can not source one then you a Y connector, in it's place.
19
This worked for me if may do for you too
This is what the valve looks like inside, here is a small diaphragm, this can fail which stop the water getting to the jets.
