O-Rings in faucets are usually the source of your leak.  This article will show you how to replace them.


How To Replace O-Rings In A Faucet

  1. Make sure your faucet is all the way off. You can either shut the water supply to the faucet or simply turn the faucet to the "off" position if the leak is not that bad.
  2. Locate the head of your faucet, which is the part that unscrews. Take your crescent wrench, attach to the head, and slowly but firmly loosen the head. Remember the "righty tighty/lefty loosy" rule or you will find yourself with a broken faucet head. Once the head is loosened, unscrew it by hand to prevent any thread damage.
  3. Remove the O-ring. If it isn't laying in the head of the faucet, it is attached to the faucet itself right where the head and faucet meet. Replace the old O-ring with your new one. Ensure the O-ring is laying flat and in place.
  4. Hand screw the head back onto the faucet. Ensure the O-ring is not in the way of the threads or you will be repeating this process again. Once the head is all the way screwed on, use the crescent wrench to firmly tighten the head. Again, be careful not to twist too hard!
  5. Turn your water supply back on for ten seconds and back off. Wipe the head and watch for 60 seconds to see if there are any more leaks. If there are no leaks, congratulations! You have successfully replaced your O-ring.
