Beofre I start ripping things apart, does anyone know where this is located? The manual just says that it is between the hose to the rear wash/wipe and the main hose going forward along the chassis. I can't see whether it is within the rear door frame or behind the trim in the loadspace. It would be a shame to spend half a day finding out if someone on this group knew already.
Er, sorry, Disco 2, 2001MY.
Rear wash works fine, but recently has had a delay of ~5 seconds before water comes out. I am assuming the valve has failed and is allowing water to drain back towards the reservoir.
TIA
