Step 6 · Turn Water On and Test for Leaks

The final step is to test your work. Go back to the shut-off valve and open it slowly and completely. Return to the outdoor faucet and inspect the packing nut area closely for any signs of water drips or seepage. Turn the faucet on and let water flow, then turn it off again. Check for leaks in both the on and off positions. If a small drip appears from the packing nut, use your wrench to give it one last, very slight (1/8 turn) tightening. If the leak is gone and the handle operates smoothly, the repair is complete.
