TheBeastie Posted October 31, 2009 Share Posted October 31, 2009 How do you normally set up washers for the rear window? I presume put a separate washer pump into the engine compartment coming off the washer reservoir and then route plastic piping through to the bit you put above the rear door. Slightly concerned it will be very vulnerable to freezing solid in winter, although I suppose could insulate it. Is this correct way , or is there a better way? Also is there a combined washer/wiper Carling type switch you can get - I envisaged click half way and wiper works, push down fully and washer kicks in, release and it jumps back to wiper just on???

defender dinky Posted October 31, 2009 Share Posted October 31, 2009 hi,couldn't you put a T peice into exsisting front ones run it to the back, when you wash the front it might wash the back sametime just a thought defender dinky Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted October 31, 2009 Share Posted October 31, 2009 Mine, which had the proper LR setup, consists of a pump in the bottle (double pump bottle) and then a tube which runs up the nearside windscreen pillar, along the roof edge and then onto the rear jet. A non-return valve just after the pump stops the fluid draining back into the bottle between washes. Never froze in mine, the washer fluid stops it doing so I believe. I've seen setups where the pump is in the door in a bag thing too though. Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted October 31, 2009 Share Posted October 31, 2009 Slightly concerned it will be very vulnerable to freezing solid in winter, although I suppose could insulate it. Surely, If it's going to freeze in the pipe, it's bugger-all use as screenwash anyway?! My factory 90 Hardtop has the pipe with the one-way valve and then up the A pillar and along the inside of the roof, as described above, and has been fine.

Dads Toy Posted November 1, 2009 Share Posted November 1, 2009 Same here, if you haven't already got it you need the washer bottle with 2 pumps in it then as all the others say up the pillar and along the roof inside. If anyone's found a Carling switch like you want I'd also be interested. Malcolm Quote Link to comment Share on other sites More sharing options...
Ex Member Posted November 1, 2009 Share Posted November 1, 2009 I suggest putting the NRV close to the washer nozzle. It prevents the line from self draining out the nozzle over time. Freezing? Do you guys use plain water? That does not wash very well.... For a switch , you could get the genuine one. I just went to a wreckers and picked a suitable one of of some car, that runs both the wiper and wash.

errol209 Posted November 5, 2009 Share Posted November 5, 2009 I suggest putting the NRV close to the washer nozzle. It prevents the line from self draining out the nozzle over time. Sorry to be all scientific, but it makes no significant practical difference where you put the NRV between the pump and jet* on a Land Rover. That said, the LR location (just above the passenger door) does seem a bit odd, as the LR NRV is HUGE. * "Bottom" is better if your jet is more than 34 feet higher than the pump, as the NRV at the jet end in this case will just give you boiling washer fluid, due to the vacuum Quote Link to comment Share on other sites More sharing options...
Ex Member Posted November 5, 2009 Share Posted November 5, 2009 Sure it does. The length of line after the NRV can self drain as air works into the system back through the nozzle. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted November 5, 2009 Share Posted November 5, 2009 Only if the water can go somewhere, which if the jet is the highest point (and it is)...it can't. I put the non-return valve (get it from an aquarium place by the way, same size as the airline hosing, about 20p each) directly after the pump and I had no discernible delay in pressing the button and getting the spray come out the back.
