Facilities, Cleaning & PestsQuestion 498 of 500
A maintenance worker ties a well-water line into the building's drinking water piping. Why must the manager stop this?
a.It reduces the water pressure at the dish machine's final rinse
b.It voids the plumbing permit issued for the building
c.It creates a cross connection with a system of unknown quality
d.It raises the water hardness above the sanitizer's limit
Explanation
No person may create a cross connection by joining the drinking water system to a non-drinking water system or a water system of unknown quality, and non-drinking water piping must be durably identified so it is readily distinguishable. Pressure and hardness are operating problems; a cross connection is a contamination pathway into every tap in the building.
