I need to move the pipe between my cold water tank and the drain cock. As there is no valve between the two I am planning to use a freeze spray to form an ice plug and then quickly swap over to the new bit of pipe.
Now, the drain cock is connected via a 22mm pipe. I bought a pipe freezing kit in a well-known DIY-shed. When I got it home it only mentions 12 and 15mm pipe. I have tried the jacket on a 22mm pipe and it fits perfectly.
So, I was wondering. Has anyone tried using a Wickes pipe-freezing kit on a 22mm pipe? How long did the ice plug last there?
Now, I can already hear the alarm bells ringing in many heads: "why isn't he just going to drain the whole system down first, rather than risk 100-odd gallons of cold water coming through his ceiling?". Good question. Well, using the drain cock is my fall-back option. I just really don't want to have to drain my cold cistern. Just seems like a lot of bother to me.
