Step 3 · Install the Water Supply Lines

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

Run the hot and cold water supply lines to the marked valve locations. Connect the PEX lines to the supply stubs using appropriate fittings. Securely tighten all connections to prevent leaks. Consider using a torque wrench for consistent tightening.
