Most saddle valves are designed to work with standard rigid copper pipes—they are not recommended for PVC, CPVC, or PEX plastic pipe. They are also designed for water systems with a maximum pressure of no more than 125 psi.

Are saddle valves illegal?

Most state and local codes prohibit the use of a saddle valve, also known as a piercing saddle valve, saddle tap or needle valve, consisting of a clamp that punctures a hole in an existing water intake pipe. It is a shortcut used instead of installing a more permanent and secure connection.
