Under what circumstances may a saddle valve be used to connect an icemaker or refrigeration line?

• A. Always
• B. Only with a permit
• C. Never
• D. Only for temporary use

Answer: (C)

Tap connections for icemakers and refrigeration must be made with a proper shutoff valve and a dedicated supply line, not by piercing the pipe. A saddle valve clamps onto a copper line and pierces it with a needle, creating a small, hard-to-repair hole that can leak or corrode over time. It also doesn’t provide a reliable, code-compliant shutoff and can pose backflow and contamination risks. Because of these safety and code concerns, saddle valves are not permitted for potable-water connections to icemakers or refrigeration lines in typical Illinois plumbing practice. The correct approach is to install a proper cold-water shutoff valve and run a dedicated supply line to the appliance.
