Step 9 · Turn On Water and Check for Leaks
Double-check that all connections are tight. Place a dry paper towel under each connection point to make leaks easier to spot. Turn both shutoff valves back on by rotating them counter-clockwise slowly. Do not open them abruptly, as the sudden pressure can damage components. With the water on, use your flashlight to meticulously inspect every connection you made: where the supply lines meet the faucet, where they meet the shutoff valves, and the sprayer hose connection. Look and feel for any drips of water.
