How to freeze a pipe with a leaking joint?

[Psyclist]

Evening all,

I've dropped a bit of a bo**ock this afternoon when extending an old pipe that comes out of the ground to use as a hose pipe.

I have been completely unable to locate any service valves for it so used a freezing kit to plug it while I cut the broken old tap off it to fit a new gate valve, pipe and hose tap.

Freezing went fine, I cleaned up the end of the old pipe, fitted the new bits and nipped everything up and then started tidying up while I waited for the freezing kit to thaw.

Got a bit of a fright when the ice plug went because I hadn't checked that the tap was shut so it suddenly started spraying water everywhere, but I turned the tap off and found a tiny leak spraying from the bottom of the gate valve.

I tried to nip it up a little more in case I hadn't tightened it enough and it made no difference so I obviously need to redo it.

Only thing is, I can't see the freezing kits working again if the water is moving through the pipe at all.

Is that right? If so, what can I do about that? How do you work on a leaking joint with no form of isolation?

Cheers all!

What freezer kit are you using? Why are you fitting a gate valve to mains water supplies?

TIGHTEN IT UP.
if that fails RUN AWAY.

I had it lying around, it was the right size for the pipe and I've seen a lot of hose taps fail so wanted some kind of isolation before the hose tap.

The freeze kit was a jacket and a 415ml can of Arctic Spray.

If it's a gate valve, then you could use a Jet Swet. Corgi sell them;

If it's outside, do it live.

If you turn all the taps in the house on then how much does that reduce the leak?

No stopcock at the inlet to the house?

That's what I can't find. I've looked around the house for nearly two hours and the only stopcock in a plastic lid that I could find made absolutely no difference whatsoever so I can only assume it goes to somebody else.

How come you could freeze it in the first place?

 

[Psyclist]

It wasn't leaking. It just had a valve on it that you could open with a wrench but couldn't attach anything to because it was smashed so the water wasn't running at all when I froze it.

You'll not be able to freeze it again with water flowing. I've got big f.ck off CO2 gear & even with that it's a waste of time.

Do it live or a Jet Swet as I suggested.
