Hi
My water is currently off as I'm doing up my bathroom.
While I'm at it, I'm thinking about replacing the broken gate valve in my airing cupboard (I have bought the correct 22mm replacement valve already).
However, before I proceed, I'm a bit nervous about it as when I started to open one end of the broken valve, water came out. Now I know there is going to be 'some' water that is already in the pipe, but can someone confirm just exactly where I need to turn off the water to prevent a flood while I'm doing this?
I have provided links to a couple of photos, but for clarification, the pipe in question comes down from my loft and down into the BOTTOM of my hot cylinder. Before it enters the cylinder, there is a drain cock.
I have turned off the tap in the loft (on the pipe leading out of the water tank), so do I just need to empty the pipe using the drain cock then remove the valve, or will water come out of the cylinder and up out of the pipe since I have removed the water pressure coming down from the tank? Is it even necessary to drain this piece of pipe (will there only be a bucketful or so?
Pictures are HERE
Hope that's clear!
