Bathroom Sink Faucets Leaking: Causes and Solutions

Leaking bathroom sink faucets are a common household problem that can waste water and increase your utility bills. While some leaks may be minor and easily fixed, others may require professional attention. Here's a comprehensive guide to help you identify the causes of leaky bathroom sink faucets and provide solutions for fixing them.

Causes of Bathroom Sink Faucets Leaking

Worn-out washers: Washers are small, rubber or plastic discs that create a seal between the faucet handle and the valve stem. Over time, washers can become worn or damaged, leading to leaks.
Damaged O-rings: O-rings are rubber seals that prevent water from leaking around the base of the faucet handle or spout. Like washers, O-rings can deteriorate and cause leaks.
Loose or damaged handles: If the faucet handles are loose or damaged, they may not be able to create a tight seal against the valve stem, resulting in leaks.
Corroded pipes or valves: Corrosion can weaken pipes and valves, causing them to leak. Rust is a common cause of corrosion, especially in areas with hard water.
Faulty cartridges: Cartridge faucets use a single, replaceable cartridge that controls water flow and temperature. A faulty cartridge can cause leaks from the spout or handle.

Solutions for Bathroom Sink Faucets Leaking

Depending on the cause of the leak, there are several solutions you can try:

Replace worn-out washers: Worn washers can be easily replaced by following the manufacturer's instructions. Turn off the water supply, remove the faucet handle, and replace the old washer with a new one.
Replace damaged O-rings: O-rings can be found on the base of the faucet handle or spout. To replace them, remove the handle or spout and replace the old O-ring with a new one.
Tighten loose handles: Loose handles can be tightened using a wrench or screwdriver. Turn off the water supply and tighten the handle nut located under the handle.
Replace corroded pipes or valves: If corrosion is the cause of the leak, you may need to replace the affected pipes or valves. This task may require professional plumbing skills.
Replace faulty cartridges: Cartridge faucets may require the replacement of the entire cartridge. To do this, shut off the water supply, remove the faucet handle, and unscrew the cartridge. Replace the old cartridge with a new one and reassemble the faucet.

If you encounter a leak that you cannot fix yourself, it's recommended to contact a qualified plumber for assistance. They will have the necessary tools and expertise to diagnose the problem and provide a lasting solution.
