Multiple Choice

The water service shall have piping not less than _____ apart from the sewer.

Explanation:
Not less than five feet of horizontal separation between the water service and the sewer line is required to protect the potable supply from potential cross-connection or backflow problems. This distance gives a safe buffer so that if there’s a leak, backup, or sewer gas, it’s less likely to reach the water line, and it also allows room for proper maintenance and installation clearance around both pipes. Smaller distances would increase the risk of contamination, while longer distances aren’t required by this rule.
