Suspicious Fluid Leak

[The Monzta]

I noticed a puddle of fluid under my SVX yesterday. I looked underneath and there was a constant drip of cool water just inboard of the LHS front wheel (passenger side here in the UK).

The water was leaking from a rubber pipe protruding from the lower bulkhead and looked to be some sort of vent or overflow pipe.

As my aircon has been on permanently lately due to us here in Britain having an unseasonably good summer......more than three days without snow I wondered whether the water leaking was something to do with the aircon.

The puddle is quite large and I've never had anything like this on other cars with aircon.

Should I be worried or is this just another innocent SVX idiosyncrasy?
