Most states and localities require plumbers to be licensed. Although licensing requirements vary, most states and localities require workers to have 2 to 5 years of experience and to pass an exam that shows their knowledge of the trade and of local plumbing codes before they are permitted to work independently. In addition, most employers require plumbers to have a driver’s license.
Water heaters are tasked with heating the water that passes through the pipes to every shower, tub, and sink. These heaters are also supposed to heat water for the washing machine and dishwasher. These units can hold up for a long time, but may begin to cause problems over time. When the heater does not heat water properly all the time, leaks, or makes odd noises, homeowners will know that there is a problem. A water heater that begins to leak could start flooding the house at any moment. A water heater that makes odd sounds could be under pressure and about to burst. In each of these cases, it could be dangerous for the homeowner, and only a licensed Manhattan plumber can fix the problem or replace the water heater altogether.
Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, dies, and joining tools such as soldering torches and crimp tools. New tools have been developed to help plumbers fix problems more efficiently. For example, plumbers use video cameras for inspections of hidden leaks or problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.
