Tranmision Lines Carry the water from the source to the storage areas. They are generally the most expensive because they are the largest and thickest pipes in the water delivery system. The closer the storage tanks are to the source the lower the cost will be.
Distribution Pipes deliver the water to the end user. The minimum diameter is 2 inches but lines which service fire hydrants must be at least 6 inches. To protect the water from contamination, the potable water pipe should be at least 10 feet from sewer pipes and in separate trenches.
Iron pipe was a lower-cost alternative to copper, before the advent of plastic materials suitable pr portable water. Special non-conductive fittings must be used to join them with other metallic pipes, except for terminal fittings, in order to avoid corrosion owing to electrochemical reactions between dissimilar metals
Wooden pipes were often used in Montreal and Boston in the 1800s. The pipes were hollowed-out logs, which were tapered at the end with a small hole in which the water would pass through. The multiple pipes were then sealed together with hot animal fat.
Lead Pipe's where a perfered materials for centuries due to the malleability. For years this was a source of lead related health problems including still births and high rates of infant mortality. They remain in many households. It is no longer legal to install lead pipes in the US.
PEX is a cross-linked polyethylene. The material is more durable under chemical exposure, extreme temperature changes, and better resists creep deformation, therfore PEX is an excellent material for hot water and other applications.
Copper Pipe is widely used for potable water plumbing because of their corrosion resistance and safety. Plumbers experienced in Copper Pipe installation and repair are common. They are easy to work with because of it's malleability and fittings are easily soldered. Copper pipe has sometimes failed due to pinhole leaks a company called CuraFlo has made exceptional strides in rehabilitating copper pipe.
Galvanized Galvanizing is done by the application of molten zinc to pre-formed steel pipes to provide a corrosion resistant coating. Many galvanized pipes in old buildings were manufactured using zinc that probably contained high levels of lead, which is a common impurity in the zinc. It was not until 1986 that the Wheatland Tube Company became the first galvanized pipe manufacturer to be certified to ANSI/NSF Standard 61 for its hot dip galvanized pipe. Galvanized pipes are still common in older homes and many commercial buildings. Galvanized pipes will corrode over time. - 15224
