Install the Angle Stop Valve

What happens here

With the threads properly sealed, carefully thread the angle stop valve onto the prepared copper fitting. Start by hand-tightening the valve to ensure it engages correctly and doesn't cross-thread. Once hand-tight, use an appropriate wrench, such as channel locks or an adjustable wrench, to firmly tighten the angle stop. Ensure it is oriented correctly for your installation and secured tightly enough to prevent leaks, but avoid over-tightening which can strip the threads or damage the valve. This completes a 'quality angle stop install'.

Goal: Securely attach the angle stop valve to the copper piping.
