Alice tells me that the engineer came out early this morning, and had a look at the boiler.  He’s apparently tightened everything up, and has stopped the joint from leaking.

He doesn’t understand where all of the water came from, so its possible that a lot of this was spilt when the system was installed,  but the pipe was definitely leaking last night, and the towel and cardboard were certainly damp this morning.

Lets hope that its all now sorted and that the leak is fixed.
