In addition to high-tech equipment used to find leaks, a plumber will need specialized tools designed specifically for fixing plumbing problems. A plumber uses pipe wrenches, flaring pliers, pipe vises, pipe cutters, pipe bending machines, thread sealing tape, crimp tools, and many more. You want to leave the repair to a professional who knows what each of these tools is used for rather than you trying to fix a water leak yourself. Leave it to the professionals to get the job done.
