Pair of wife's old tights and an elastic band over filler neck when topping up simplz!

I'm guessing the one way valve only stops washer fluid draining back into the tank so that when you hit the washers instant flow. I'm sure this is a fairly recent thing so replacing that 3 way valve with a non back flow version or carefully drilling out the tube isn't a major issue.

"Fairly recent"? Not sure why that's relevant. The J10 had one too

Just cured my dribbling washer jets in half an hour. Similar to Gloucesters method but I didn't strip much down. I removed the 6 plastic clips that hold the plastic cowling together at the base of the wiper arms. Removed the 4 clips that hold the silver heat shield in place. I parted the plastic cowling just enough to put my fingers in and fished around for the waterpipe. It's possible to pull the pipe assembly out and simply pull the 3 pipes from the valve. Drilled straight through the valve assembly removing (destroying) the one way valve. Cleared the debris from the assembly and refitted the 3 waterpipes. Pushed it back into the cowling and replaced the clips. Sorted.
