Water Service Pipe Lines
Water service pipe lines extends from the potable water source to the interior of buildings.
A "water-service" pipe line extends from the potable water source to the interior of a building. Inside the building the "water-service" pipe becomes a "water-distribution" pipe.
A water service pipe must be rated for the pressure produced by the water source and in the service line by pumps or static differences.
- it is common to rate water service lines for more than 160 psi (11 bar) and temperatures below aprox. 75oF (25oF)
Commonly used materials in water service pipe lines are
- Cast iron pipe (ductile pipe) - used in large water mains
- PE - Polyethylene
- PVC - Polyvinyl Chloride
- PB - Polybutylene
- Asbestos cement pipe
Other commonly approved and rarely used materials are
- ABS - Acrylonitrile Butadiene Styrene
- Brass pipe
- Copper tube - can be used as service lines without joints. Primarily used as water distribution pipes.
- CPVC - Chlorinated Polyvinyl Chloride
- Galvanized Steel
