Bathroom Faucet Leaking Under Sink

A leaky bathroom faucet is a common household problem that can waste a significant amount of water and increase your water bill. While some leaks may be minor and easy to fix, others may require professional assistance. In this article, we will provide a comprehensive guide to help you identify and repair a leaking bathroom faucet under the sink.

Identifying the Source of the Leak

The first step in fixing a leaky faucet is to identify the source of the leak. There are several common locations where leaks can occur:

Faucet handle: Leaks from the faucet handle are often caused by worn-out O-rings or washers.
Cartridge: Cartridge faucets contain a removable cartridge that controls the flow of water. Leaks from the cartridge are usually caused by a damaged seal or worn-out parts.
Supply lines: The supply lines connect the faucet to the water supply. Leaks from the supply lines can be caused by loose connections, damaged hoses, or corrosion.
Drain assembly: The drain assembly is the part of the faucet that allows water to drain from the sink. Leaks from the drain assembly can be caused by a worn-out gasket or a loose connection.

To identify the source of the leak, inspect the faucet carefully while it is running. Look for any visible dripping or spraying water. You can also use a flashlight to check for leaks in hard-to-reach areas.

Repairing the Leak

Once you have identified the source of the leak, you can proceed with the repair. The type of repair will depend on the location of the leak.

Handle Leaks: Handle leaks can be repaired by replacing the O-rings or washers. To do this, follow these steps:

Turn off the water supply to the faucet.
Remove the handle by unscrewing the handle screw.
Replace the O-rings or washers with new ones.
Reinstall the handle and tighten the handle screw.
Turn on the water supply and check for leaks.

Cartridge Leaks: Cartridge leaks require replacing the entire cartridge. To do this, follow these steps:

Turn off the water supply to the faucet.
Remove the handle and any decorative caps.
Unscrew the cartridge retainer nut.
Pull out the old cartridge and insert the new cartridge.
Tighten the cartridge retainer nut.
Reinstall the handle and any decorative caps.
Turn on the water supply and check for leaks.

Supply Line Leaks: Supply line leaks can be repaired by tightening the connections or replacing the hoses. To do this, follow these steps:

Turn off the water supply to the faucet.
Using a wrench, tighten the connections between the supply lines and the faucet.
If the connections are still leaking, replace the supply hoses.
Turn on the water supply and check for leaks.

Drain Assembly Leaks: Drain assembly leaks can be repaired by replacing the gasket or tightening the connection. To do this, follow these steps:

Turn off the water supply to the faucet.
Place a bucket under the sink to catch any water.
Using a wrench, loosen the nut that holds the drain assembly in place.
Pull out the drain assembly and inspect the gasket.
If the gasket is worn or damaged, replace it with a new one.
Reinstall the drain assembly and tighten the nut.
Turn on the water supply and check for leaks.

Preventing Faucet Leaks

To prevent future faucet leaks, follow these tips:

регулярно проверяйте кран на наличие протечек и немедленно устраняйте любые проблемы.
Use low-flow faucets and aerators to reduce water consumption and stress on the faucet.
Avoid using harsh cleaning products on the faucet, as they can damage the finish and lead to leaks.
Install a water softener if you have hard water, as it can reduce the buildup of scale and mineral deposits that can contribute to leaks.
