When it comes to pipe maintenance the easiest thing to do is obviously shut the entire system down and work at your leisure to fix any problems. Of course this not always an option. In some cases work needs to be done without shutting off the water supply. In these cases a very handy tool to have around is the Ridgid SuperFreeze. The SuperFreeze pipe freezer unit allows you to keep the water system operating while making repairs. The RIDGID SF-2500 is a mini-refrigeration unit that circulates self-contained refrigerant to its aluminum freeze heads. These heads form ice plug in as little as 5 minutes in copper tube up to 2 1/2" or steel pipe up to 2". The ice plugs remain frozen while the unit is on allowing ample time to repair any sprinkler head, valve, leaking pipe, etc. 
The Ridgid pipe thawers units KT-190 & KT-200 do just the opposite; they thaw pipes that may have frozen. Recently we’ve seen a bit of a spike in interest for these units with colder weather and ice storms shutting off power in some areas. Not a good combination for pipes full of water. Thawing Units provide continuous heating to quickly thaw 1/2" to 1 1/2" frozen metal pipes. With these lightweight, versatile units, there is no need to dig or tear apart walls. Simply attach the clamps to the metal pipe on each side of the frozen section and the pipe is thawed within minutes.
Both of these types of units can be very handy for any contractors. For more information on these or any other Ridgid Plumbing Tools contact the experts at Ohio Power Tool (800-242-4424) and they will be happy to help you find the right tool for the job.
