What tool is used to connect service lines 2 inches or smaller?

• A. Small drilling machines
• B. Hammer and chisel
• C. Socket wrench
• D. Soldering iron

Answer: (A)

Connecting a service line to the main when the line is 2 inches or smaller is done with a small-diameter tapping operation. A small tapping machine (drilling tool) is used to drill into the main and tap a branch for the service, often with a valve installed for control. This method provides a precise, watertight connection without damaging the main, which crude methods can do.

Hammer and chisel is too crude and risky for tapping into a live main. A socket wrench is for tightening fittings after a connection is made, not for creating the branch tap. A soldering iron is used for joining copper pipes, not for tapping into the main to establish a service line.
