So the plumber has just left.
Let me explain. 7:30 this morning I heard a hiss coming from the bathroom. Seems the hot water pipe at the sink just burst. Just like that.
Apparently the new type of webbed metal pipe with a rubber core (used universally for the last 15years instead of copper) has a tendency to just burst without warning!
My post is to warn people to locate and practice using your stopcock. Keep it oiled as it took 2 men and a hammer to get mine moving - with boiling hot water gushing out for the whole 40 minutes it took.
I thought all I needed was to know where it was, never occurred to me to make sure I could turn it 🤦♀️
