A Price Guide and Information Sheet on Replacing and Installing a Stop Tap or Stopcockl


99 times out of 100 there’s only one stop cock per household, it’s usually in some inaccessible place under the kitchen sink and you never go near it.
The problem is, when you do want to turn it off it’s because you’re in trouble. When you are in trouble you are at the mercy of the
plumber and he charges an arm and a leg when he’s feeling benevolent!
Do yourself a favour. See if yours is accessible and working. If it’s not, get it moved / replaced at a time when you are in charge and not the plumber.
If you need a new one it’s because the existing one is seized. If it’s seized it’s because it’s old. If it’s old it’s probably an “in line” affair on mild steel or even lead pipework. Bother!
