Step 10 · Final Test and Cleanup

With no leaks detected under the sink, turn the new faucet handles on, one at a time. Let the water run for a minute to flush any air or debris from the lines. Test the sprayer function. While the water is running, perform one final leak check under the sink. If everything is dry, the installation is complete. Wipe up any water in the cabinet, remove your tools and bucket, and replace the items you stored under the sink.
