I like the sleeve solution, I'm just concerned about what I can't see...

If the tube is badly rusted, it's not unthinkable that it could still fall away from the insert and leak water into the car.

The idea of the sleeve is that it extends inside beyond the end of the original drain hole so that if the original drain did become disconnected then the insert will hold everything in place, at least hopefully long enough until you detect it on your next regular inspection, and minimise any water ingress. _______________________________________________

Thank you so much ReggieMac for sharing the sleeve solution that simplifies the procedure immensely!

You can also pull the headlining away, just in front of the rear grab handle and shine a torch up to see where the rubber tube attaches.

I gave mine a wiggle - one seemed solid, the other came off So I've cleared out all the rusty remains of the original tube that was inside it and now need to reconnect it to the insert. However, I need another bit of pipe as the insert is all that remains and is narrower than the original drain. I'm guessing a short length of the Hep20 pipe will work best

I also had one that was blocked at the exit as well - that's located in front of the secondary battery. Easy to clear with a bit of strimmer cable.

Almost there.......
