You are braver than me!
I've seen those kits but in the end chickened out and found the isolating valves.
In our place here a lot of them are in the airing cupboard along with the hot water cylinder etc.
Maybe if the watter in the pipes is already cold....
Well done mate!
The pipes were hot feeds to the taps, I did make sure the were not hot as id need to work faster haha
After using the kit im sure it could be done even if the pipe was warm id use 2 of the foam pads to
give me more time. Took about 12 mins to defrost after id removed the pad. Tbh I though whats the worst
that can happen.......
I get 2 HAMMERS & flatten the pipe (now I know you've got a smile)
