Faucet leaks can be highly frustrating and can take a toll on your water bills. Furthermore, if you let the leak continue, it can cause damage to your walls, floors, and other fittings. It isn't always necessary to call a plumber straight away.Understanding how to identify and fix faucet leaks can save you a lot of money and time.Simply follow this guide to identifying and fixing your leaky faucet.

Identifying the leak

When it comes to identifying a faucet leak, it is essential to thoroughly examine the faucet. Faucet leaks are often seen in the handles and spout. The leak could also be due to a damaged valve seat, seal, or O-ring. Before any repair occurs, ensure you turn off the water supply via the shut-off valves under your sink or in your basement.


If the faucet drips continuously, the problem could be due to a worn-out O-ring. The O-ring is located at the base of the spout, and it becomes damaged and loose over time. A professional plumber could help you repair it.


If you notice a steady stream of water even when the faucet is shut off, it may be due to a damaged or corroded valve seat. You can replace the valve seat - best done by a plumber.
If water drips directly from the faucet spout, drip by drip, it could indicate that the cartridge needs replacement.

Fixing the leak

Once you have identified the source of the leak, the next thing to do is to fix it. This part varies depending on the cause of the leak.
For O-ring replacement, the first thing to do is to remove the faucet handle by loosening the screw that holds it in place. Next, you will need to remove the stem. Use a wrench or pliers to grip the top of the stem and twist it counterclockwise to get it out. Once out, check the O-ring or washer and replace any damaged ones.
For the valve seat and cartridge replacement, you will need to remove the entire faucet unit. Once out, remove the old valve seat and install the new one. For the cartridge, use a cartridge puller tool to remove it and replace with a new one.

Preventing future leaks

Once you have repaired your leaky faucet, it is essential to take precautions to prevent future leaks. Maintain your faucet by regularly cleaning it and checking for damaged parts.
In conclusion, fixing a leaky faucet can be time-consuming and frustrating. Still, identifying the source of the leak and repairing it can save you money, time, and the inconvenience of a flooded home. Always be sure to turn off the water supply before any repair, and don't hesitate to call a professional plumber if you are not confident. Now, you can enjoy a leak-free faucet and your new knowledge on how to fix it.
