Commercial Plumbing Time Study

About the Study

New Content Item

REHAU worked with Home Innovations Research Lab to conduct a side-by-side installation time study of a hot- and cold-water commercial plumbing system conducted in two identical sections of a mockup hotel.

Each section included a hallway and four guest suites, each suite having five plumbing fixtures.

Installation time was evaluated for the following systems:

  • REHAU RAUPEX® PEXa pipe and EVERLOC+™ fittings; 
  • PEXa pipe with cold expansion fittings;
  • Copper pipe with solder fittings; and 
  • Copper pipe with press fittings.

Each of the four systems was installed on a section of the mockup by two different plumbers. The installations included 1/2, 3/4, 1, 1 1/4 and 2-inch piping, representing a mix reflective of a hotel plumbing system.

Key Findings: EVERLOC+ Installs Faster
