Pipe is available in rigid "joints", which come in various lengths depending on the material. Tubing, in particular copper, comes in rigid hard tempered "joints" or soft tempered (annealed) rolls. PeX and CPVC tubing also comes in rigid "joints" or flexible rolls. The temper of the copper, that is whether it is a rigid "joint" or flexible roll, does not affect the sizing.[19]

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.

Wooden pipes were used in London and elsewhere during the 16th and 17th centuries. The pipes were hollowed-out logs, which were tapered at the end with a small hole in which the water would pass through.[16] The multiple pipes were then sealed together with hot animal fat. They were often used in Montreal and Boston in the 1800s, and built-up wooden tubes were widely used in the USA during the 20th century. These pipes, used in place of corrugated iron or reinforced concrete pipes, were made of sections cut from short lengths of wood. Locking of adjacent rings with hardwood dowel pins produced a flexible structure. About 100,000 feet of these wooden pipes were installed during WW2 in drainage culverts, storm sewers and conduits, under highways and at army camps, naval stations, airfields and ordnance plants.

Plumbers in Australia have licensing requirements that differ from state to state but it is generally accepted a 4-year apprenticeship with a further minimum experience of 2 years (6 years total) and a further curricular requirement as a benchmark for licensing. Licensed plumbers are also expected to maintain minimum relevant training requirements to maintain their plumbing license
