Step 4 · Install the New Shower Diverter Valve

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.

Install the new diverter valve, carefully following the manufacturer's instructions. If using Teflon tape (check manufacturer’s recommendations), wrap several turns around the threads to ensure a watertight seal. Securely tighten all connections, using a deep socket set or adjustable wrench if necessary. Some valves have O-rings, eliminating the need for Teflon tape.
