Water distribution pipes is 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
