Three weeks ago my brother came to visit to change my naff and somewhat broken taps.  After 24 hours, one leak, cold water that wouldn't isolate fully, trips into the loft without a torch and the purchase of a large quantity of plumbing supplies we both left the flat with the taps in place, a limited amount of cold water and fingers crossed there'd be no leaks.

I returned to the flat in some trepidation and I was greeted by ...

... my beatiful taps.  No leaks in sight and after a minor tweak plenty of cold water.  On the otherhand the fridge was a totally different matter!!! And I think I've figured out how to isolate the water in my flat without visiting the loft.
