Colin Lindsay Posted July 20 Report Share Posted July 20 Too advanced for Heralds!! Just a simple T piece, very early ones were brass, later plastic - same with the washer bottle, a brass valve in the lid of two of mine but the rest just a straight through pipe; I'm assuming that's original and a real bonus if not!

johny Posted July 20 Report Share Posted July 20 They could have avoided all this by just mounting an NRV in each of the inlet and outlet of the pumps - would have been so easy to maintain and replace! 1 Link to comment Share on other sites More sharing options...
Colin Posted July 20 Author Report Share Posted July 20 Er . . . (my poor sipleton head):- is an NRV needed on the water pick-up tube in the water bottle? There was one on it and I've renewed it . . . Best, Colin Link to comment Share on other sites More sharing options...
johny Posted July 20 Report Share Posted July 20 Fraid so, one on the suction side of the pump and another(s) on the discharge side and of course all must allow flow in the right direction although in this case it would be difficult to install them the wrong way round😁 Link to comment Share on other sites More sharing options...
Colin Posted July 20 Author Report Share Posted July 20 Blimey, Hazel!! I am really grateful to you all for the variations and specs on what I thought should be the very simplest item of all to sort. I am going to have wait for a partial or full dismantle until another 10 days 9r so due to being otherwise occupied. You'd think in 35 years I'd recall what I'd done. Although very nicely hidden by insulation and other wiring, I think I can see I've inserted a plastic 'T' piece in the piping to the nozzles; so I am thinking it does not have an NRV in it, leaving that function to be performed by my glass balls in the metal under-dash nozzle feed pipes! BUT - as I am unable to draw water into the diaphragm whatever the situation further toward the screen nozzles, I think I will commence with sucking washer fluid up the diaphragm feed pipe and also try to fill that, too and then plunge it all out up the system. I have some thin-nosed syringes with which I might be able to achieve this!! 😃 Again, Cheers to All. Good info and entertaining, to boot! C.

johny Posted July 20 Report Share Posted July 20 As I say test the valves before stripping stuff down. Even better with a syringe as you can try forcing water back to the bottle - no go and then, after pumping water out of the nozzles, try to suck it back - also no go👍 Link to comment Share on other sites More sharing options...
Colin Posted July 21 Author Report Share Posted July 21 As per earlier - a little exercise for me once freer than atm!! Will keep everyone posted! Cheers again, All! Best, C. Link to comment Share on other sites More sharing options...

dougbgt6 Posted August 10 Report Share Posted August 10 Just to confuse everybody, in my box of useful bits I have a flow sensor, a timer and a pump. I've temporarily connected it all together and it works. The original handraulic switch trigers the flow sensor which turns on the timer which works the pump. Another waste of time and effort when I should've been doing more important things to the car. Doug 1 Link to comment Share on other sites More sharing options...

Colin Posted August 10 Author Report Share Posted August 10 Now I'm back off hol, I'm going to pursue my, 'it all needs a good priming', theory (having been laid up ten years and the washers not need over the last 6-7 years). Think I'll film it being done and will post, if it works 😉 Best to All. C. Link to comment Share on other sites More sharing options...
Colin Posted August 19 Author Report Share Posted August 19 Here I am! Holiday over. New non-return valve at the bottom of the washer bottle tube. I used a syringe to try to draw up water from the bottle and found it was virtually impossible. I have no idea why. Eventually the syringe pulled some bottle water up. I primed the new manual diaphragm pump. Connected input & jet output pipes - and pumped. Bingo . . . Yes, water out of each of the jets! Except, great pressure and spurt (mainly over the roof if I'm honest) from the passenger side jet . . . and a pretty poor pressure (more of a dribbly spurt) from the driver's jet. I'm hoping it may be just a bit of a sticky non-return (if there is one) under the jet which will ease off. But at least there is something at the screen now. May give the driver's side a poke from the top, with some thin wire in case my previous anti-blockage efforts haven't cleared summat, but otherwise, not sure why the driver's side jet isn't spraying out with the pressure it should have.

johny Posted August 19 Report Share Posted August 19 Progress! Get some cleaner in the system and give it good work through and then set up the directions of the nozzles👍 Using it regularly will help keep all working... Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 19 Report Share Posted August 19 its easy for jet and the NR valve you dont know about ( Ha ) to get clogged if washing up liquid has been used it can go very solid when in unused zones just stick to the blue or pink stuff dont add any soapy stuff and note most of the ready to use screenwash is 75% water so buy the concentrate and water it down . happy squirting Pete Link to comment Share on other sites More sharing options...
Colin Posted August 19 Author Report Share Posted August 19 Hi Johny - thanks. Will do! Direction's easy enough - angle of inclination bit trickier! But until driver's becomes a bit more efficient, I'm not too concerned!! Best, C. Link to comment Share on other sites More sharing options...
Colin Posted August 19 Author Report Share Posted August 19 Hi Pete - Yes; I imagine I probably used that, all those years ago. I have a drop of Meths in atm.. I'll feed some white vinegar down the jet with my super-duper syringe and I'll just keep using them until such time . . . Thanks! Best, C. Link to comment Share on other sites More sharing options...
