PLUMBING SYSTEM

The Plumbing System is the science of installing, repairing and servicing the pipes. It includes the waste pipes, fixture traps, vent pipes, building sewers, drainage pipes and devices within and outside the house, which distributes water in the different part of house.
Plumbing system is used for water supply in building. It supplies water to kitchen toilet outlets via distribution system of pipes. Drainage system is used to get rid of human wastes through well-arranged network of drainage pipes.

PLUMBING SYSTEM

Parts of a Drainage, Waste & Vent System:

The DWV system is the largest part of any plubming system which consists of three major classes of piping and fittings in a simple drainage system.
1) Drainage Pipes : They receive and convey the used water to a public or private disposal system.

2) Fi xture traps : They provide a liquid seal protection without restricting the flow of sewage or other waste.

3) Vent pipes : They admit air to and exhaust air from all parts of the drainage system. That protects fixture traps against siphonage and back pressure.

Water Distribution Systems

The purpose of distribution system is to deliver water to consumer with appropriate quality, quantity and pressure. Distribution system is used to describe collectively the facilities used to supply water from its source to the point of usage.

1. Water quality should not get deteriorated in the distribution pipes.
2. It should be capable of supplying water at all the intended places with sufficient pressure head.
3. It should be capable of supplying the requisite amount of water during firefighting.
4. The layout should be such that no consumer would be without water supply, during the repair of any section of the system.
5. All the distribution pipes should be preferably laid one metre away or above the sewer lines.
6. It should be fairly water-tight as to keep losses due to leakage to the minimum.
