Distributing Mains and Pipes.
Distributing Mains.—The distributing mains generally extend along the streets, and are laid deep enough to avoid injury from frost heavy traffic, usually at a depth of not less than 3 ft. 6 in. from surface of the ground or pavement immediately above such pipe.
The mains vary in size. They are usually of an internal diameter of 4 in. and upwards, and made of cast iron with caulked-lead or flanged joints. The caulked-lead socket and spigot joint is still used for cast-iron mains of all descriptions. Occasionally, however, it is advantageous to use flexible joints which permit movement between adjacent pipes sufficient to enable bends to be negotiated without the use of specials.

Circulation of mains should be aimed at, otherwise dead ends wilt become troublesome owing to stagnation. Where it is impossible to avoid dead ends, frequent flushing out is necessary. The pipes, when, laid, are generally tested to twice the working pressure. Service Pipes. The service or supply pipe may be lead, copper, wrought iron, or steel. Lead pipes are extensively used, and the weight in proportion to the diameter will vary slightly in accordance with the regulations of the water authorities.
