Water-distribution pipe is the piping located inside a building
A water-distribution pipe is located inside a building and delivers potable water to the fixtures. The supply system delivering water from the potable source to the building is the "water-service" pipe.
The water distribution system includes normally both hot and cold water. The temperature range limits the materials allowed.
- it is common to rate water-distribution pipes for a minimum working pressure of aprox. 100 psi (7 bar) and 180oF (80oC)
It the the water-service to the building exceeds the rated water-distribution pressure, a pressure-reducing valve must be installed.
Commonly used and approved materials in water-distribution pipe lines are
- Copper tube
- Galvanized steel pipe
- PB - polybutene
- PEX - cross-linked Polyethylene
