Service connection from main pipe to building
Short answer
A service connection uses a ferrule, goose neck, service pipe, stop cock, water meter, and master valve to convey water from the street main to the household tap. The goose neck absorbs settlement, and the meter measures consumption.
Describe the components and purpose in the layout of the service connection from the main pipe to a private building / household, with sketch and use of each component.
A service connection is the pipe that carries water from the street distribution main to the tap or meter inside a private building.

Components and their use
| Component | Use |
|---|---|
| Ferrule (tapping) | A small brass fitting screwed into a hole bored in the main (under pressure); it gives the branch for the service pipe. |
| Goose neck (gooseneck bend) | A flexible curved pipe (lead/copper/PE) which takes up settlement and vibration, so the main pipe is not stressed. |
| Service pipe | GI, PE or PVC pipe of 12–25 mm that carries water from the main to the property. It is laid 0.6–1 m deep. |
| Communication/stop cock (curb cock) | Valve near the road/boundary, for the water authority to cut off the supply to the building. |
| Water meter | Measures the quantity used, for billing and reducing waste. |
| Master/stop valve (inside) | Lets the owner shut off the supply for repairs. |
| Pipe fittings and tap | Elbows, tees, bib cock/tap deliver water inside the building. |
The service line is laid with a small slope, with all joints made leak-tight; the meter is kept in a protective box.
