Green Plumbing

Answer: A - While residential water audits rely on the plumber’s ability to turn off the water supply in order to complete some tasks on the audit, doing so is much more difficult, if not impossible, at a commercial site. The greater number of people onsite, different uses and processes, and other considerations preclude depriving the commercial site of water for periods of time. Visual inspections are entirely feasible at commercial sites, and potential water efficiency savings uncovered may greatly exceed the cost of the commercial water audit.
