Cold Shot Pipe Freeze kits... http://www.pipemanproducts.com/Coldshot.html
Pretty neat when you have a property with a common boiler for hot water.
But unto the wicked God saith, What hast thou to do to declare my statutes, or that thou shouldest take my covenant in thy mouth? seeing thou hatest instruction, and castest my words behind thee.---Psalm 50:16-17

Ive used them on municipal water line and they work great. The one I used was CO2 and as long as the water insnt moving its fine.

The bang when the plug thaws and slaps down the pipe to the first bend always make me nervous. And like stickinit said the water cant be moving, if you are to close to a tee with water moving on the other line it can give you a fit.
I'm good at making things cold...You can ask my first two wives!

A pipe freeze works great.... as long as you know what you're doing.
There is a mechanical contractor down here in Miami that specializes in pipe freezes. He uses liquid nitrogen pumped through a jacket wrapped around the pipe. Pretty awesome.
Find someone in your area with experience doing this.

stupid question:
I am assuming that you won't be able to perform pipe freeze operations on water systems since water expands which would crack the pipe?

Personaly I have done it and it worked great. The only thing in the back of your mind is the "cracking of the ice plug". If that happens, well you know the rest.

You would be correct if they were freezing the whole pipe. However this procedure calls for freezing a short section of pipe. Originally Posted by Saman1366
