99% sure, there was water running off the underside of the rubber pipe. It could however be spray from another tube leaking but I didn't feel anything when I wrapped my hand around the pipe to feel for the leak. I think the water bypass is a good idea, however I need to fix this quick.
Does anyone know the part numbers for those pipes or where they are in the workshop manual. I have the workshop manual but haven't found a pic of them yet. I want to be able to go into Nissan and point at the parts otherwise I will no doubt end up with a door handle for a micra knowing them.
