COMMONLY ASKED QUESTIONS

How long does it take to freeze a pipe?
Freeze times will depend on a number of variables, i.e., pipe size and material, water and ambient temperatures. However, the following is a representative guide to freeze times, using 70 degree ambient and 50 degree water.

½"	copper	one or two ice plugs	5-10 minutes
¾"	copper	two ice plugs	8-12 minutes
1½"	copper	two ice plugs	25-35 minutes
2"	iron	one ice plug	25-35 minutes
2"	copper	two ice plugs	45-50 minutes
3"	iron	one ice plug	50-60 minutes

Can I freeze running water?
As a general concept the answer is no. However, because the temperature of the freeze heads on the Freeze Master® will drop to minus 40 degrees there are certain conditions where this will be possible.

I have glycol in my heating/cooling system for protection. Will Freeze Master® work for me?
Yes. If you have frost protection down to -20 degrees, Freeze Master® will freeze it. Freeze times however will be longer.

How long are the hoses and can they be longer?
The hoses are six feet and they cannot be made longer without considerable loss of freeze capability. As the Freeze Master® is completely self contained and portable, it is usually a simple matter to locate the unit near the job site no matter where you are working.

I need to freeze a 6 inch pipe, will Freeze Master® do this?
No. Without going into an explanation about thermal dynamics, we have elected to stay with the portability, safety and convenience of 110 volts.

I have high water pressure, will the ice plug hold?
We have tested copper and steel pipe to 1400 psi without moving the ice plug (the pipe did burst, however).

Will I bust the pipe when I freeze it?
No. Only a small section of the pipe is frozen, allowing for expansion beyond the area of the freeze.
