Bathroom Sink Is Leaking From Under The Faucet

A leaky faucet is a common plumbing problem that can waste water and increase your water bill. If your bathroom sink is leaking from under the faucet, there are a few things you can check to find the source of the leak and fix it yourself.

First, check the faucet aerator. The aerator is the small screen that screws onto the end of the faucet spout. It helps to aerate the water, which reduces splashing and makes the water flow more smoothly. If the aerator is clogged, it can cause water to leak from the base of the faucet. To clean the aerator, simply unscrew it from the faucet and rinse it under running water. If the aerator is damaged, you will need to replace it.

If the aerator is not the source of the leak, the next step is to check the O-rings. O-rings are small rubber gaskets that create a watertight seal between the faucet and the sink. Over time, O-rings can wear out or become damaged, which can cause leaks. To replace an O-ring, you will need to remove the faucet handle and then use a wrench to loosen the packing nut. Once the packing nut is loose, you can remove the old O-ring and replace it with a new one. Be sure to lubricate the new O-ring with petroleum jelly before installing it.

If the O-rings are not the source of the leak, the next step is to check the faucet cartridge. The faucet cartridge is a small, cylindrical device that controls the flow of water through the faucet. If the cartridge is worn out or damaged, it can cause water to leak from the base of the faucet. To replace a faucet cartridge, you will need to remove the faucet handle and then use a wrench to loosen the cartridge retainer nut. Once the retainer nut is loose, you can pull out the old cartridge and replace it with a new one. Be sure to lubricate the new cartridge with petroleum jelly before installing it.

If you have checked all of the above components and the leak is still persisting, the problem may be with the faucet body itself. The faucet body is the main housing of the faucet, and it can develop cracks or leaks over time. If the faucet body is leaking, you will need to replace the entire faucet.

Fixing a leaky bathroom sink faucet is a relatively simple task that can be completed in a few minutes. By following the steps outlined above, you can save yourself the cost of calling a plumber.
