Just thought I'd share with you that I've fixed the leak, all by myself, no plumber required (and also that the inside of under-the-kitchen-sink-pipes are disgusting: a kind of fetid, brown, rotting gloop). Note the trusty marigolds. How do real plumbers manage without them? Now I just have to decide what to do with the fifty quid I've saved... although come to think of it, it's only £25 after you take into account the car insurance fleecing from yesterday! Hope all are well, CT.
