Water Supply & DistributionQuestion 22 of 360
A reduced pressure principle assembly (RP) discharges water from its relief port during a fouling event. Where must the relief port discharge terminate?
a.Directly into the sanitary sewer with a solid connection
b.To atmosphere through an air gap so it cannot be submerged
c.Into a sealed pit under the assembly
d.Back into the potable line downstream
Explanation
The RP relief port must discharge to atmosphere through an air gap so a backflow or fouling event cannot cause submergence and re-contamination. A solid sewer connection, a sealed pit that could flood, or routing back into the potable line would defeat the protection.
