Water Service Pipe Lines

Sponsored Links

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
