TL;DR
A saddle valve is a small clamp-on fitting that pierces a copper or plastic water line with a hollow needle to tap a low-flow branch, typically feeding an ice maker, humidifier, or filter. Because the pierced hole and rubber gasket leak over time, most plumbing codes no longer permit them, and plumbers usually replace one with a soldered or push-fit tee and a quarter-turn stop.
