| Fixture Flow Rate Comparison Cross-Linked Polyethylene (PEX) Piping and Copper Tubing |
|
| Cross-linked polyethylene (PEX) and copper piping were tested at varying source pressures and two maximum runs; 60 and 100 ft, to determine if PEX and copper piping systems will deliver sufficient volumetric flow rates to the plumbing fixtures when using the same nominal size tubing. |

| ORNL: Evaluation of Residential Hot Water Distribution Systems by Numeric Simulation |
|
| The goal of this project was to simulate and compare the energy and water performance,
economics, and barriers to use of various domestic hot water distribution systems in new and
existing California residences, and to evaluate the potential statewide impact of the use of
more efficient hot water distribution systems. |

| PEX Information by PPFA |
|
| PEX piping has been used in hot and cold water distribution systems and for hydronic radiant heating in Europe for many years. Introduced into the United States in the 1980's, PEX has replaced polybutylene (PB) as the most widely-used flexible plumbing piping. |

| PEX Piping: Speeding Installation |
|
| Keith Peterson didn't want to use copper for his plumbing because of the taste it can leave in the water. He selected cross-linked polyethylene (PEX) piping for its ease of installation and cost savings, and even tied a REHAU fire suppression system into his cold water pipes. |
