Step 8 · Turn On Water and Test for Leaks

With the new angle stop in the 'off' position, return to the main water shutoff valve. Turn it on slowly and fully (counter-clockwise). Listen for the sound of pipes filling. Go back to the sink and use a flashlight and a dry paper towel to inspect the new valve. Check for any moisture around the main compression nut at the wall. If it's dry, slowly turn the handle of the new angle stop to the fully 'on' position (parallel to the outlet). Now check for leaks around the valve stem and where the faucet supply line connects. If all connections are dry, turn on the faucet and let it run for a minute. Perform one final check for any drips. Clean up your tools and towels.
