Hi John,
Is there a special connection that I can use to do this? As I said, this is for my GT6, which has a heater, so the outlet from the head is redundant as there isn't a feed in point for it... I have seen other GT6's with the take off just blanked off, so I didn't even think about the issue of water flow in that area, but now you mention it I can see the potential for overheating!
Paul.
