What is a saddle valve?

Tuesday, August 14, 2018

   A saddle valve is an easy way for a homeowner or handyman with no pipefitting experience to add a small water line to an existing pipe. It is a low-flow device and often used to run water to a refrigerator ice maker. The valve clamps around a water pipe and, when the handle is rotated clockwise, a sharp pin pierces the pipe and begins a flow of water. Unfortunately, saddle valves are prone to leakage and are specifically prohibited by the Florida Building Code:

   We call out a saddle valve as a defect during a home inspection, and recommend a T-fitting and valve as a replacement.
