Common Causes of Faucet Leakage and How to Fix Them

The faucet at the kitchen sink is one of the most frequently used kitchen fixtures when cooking and washing dishes。If the faucet at the sink is leaking at the rotating joint，here are some solutions。

What to Do If the Faucet at the Sink Leaks at the Rotating Joint

1、Loose Faucet Screws

One common reason for leaks at the rotating joint of the sink faucet is loose screws。The force applied when using the faucet can gradually loosen the screws，leading to a leaking issue。

Solution：

Use a wrench to tighten the faucet screws。Before you proceed，make sure to shut off the water supply to prevent water from continuing to flow。If the faucet screw is damaged，consider replacing it with a new one。You can visit a nearby hardware store to find a screw that matches the original。.

2、Worn Seals

Another common reason for leaks at the rotating joint of the sink faucet is worn seals。Over time，the seals in the faucet may lose their sealing ability due to prolonged use，which can cause leaks。

Solution：

Shut off the water supply and unscrew the screws at the base of the faucet to remove the seals。Check if the seals are damaged or worn。If they are，visit a nearby bathroom supply store or hardware store to purchase new seals that match the original。Install the new seals at the base of the faucet and tighten the screws with a wrench or screwdriver。

3、Faucet Cartridge Failure

If the above two methods do not resolve the leak at the rotating joint of the sink faucet，it may be due to a failure of the faucet cartridge。If the cartridge is worn or damaged，it will not effectively control the water flow，leading to leaks。

Solution：

Shut off the water supply and use a wrench to disassemble the faucet。The specific steps may vary depending on the model of the faucet，so refer to the user manual or online tutorial videos。Remove the cartridge and check if it is worn or damaged。If it is，visit a professional repair shop or purchase a new cartridge that matches the original。Install the new cartridge back into the faucet，reassemble it，and tighten the screws with a wrench。

Summary：This concludes our discussion on what to do if the faucet at the sink is leaking at the rotating joint。When using the sink faucet，if you notice a leak at the joint，first check for loose screws and tighten them with a wrench。If the problem persists，consider replacing the faucet seals。If none of the above methods work，you may need to replace the faucet cartridge。If you're unsure about how to resolve the issue，consult a professional repair technician for advice。Fixing the leaking problem can not only save water resources but also reduce water bills and improve the quality of life at home。
