Faucet
A leaky faucet is often caused by worn-out or damaged washers or O-rings. To check the faucet, turn off the water supply and remove the aerator, which is typically located at the tip of the spout. Inspect the washer or O-ring for signs of wear or damage and replace it if necessary.
Handles
Leaking handles can be caused by loose or worn-out O-rings or cartridge seals. To check the handles, remove the handle cap and tighten the packing nut, which is located beneath the handle. If the leak persists, the cartridge or O-ring may need to be replaced.

Repairing the Leak
Once you’ve identified the source of the leak, it’s time to repair it. The specific repair method will depend on the type of leak you have.
Replacing Washers
Washers are rubber or plastic seals that create a watertight seal between the faucet handle and the valve body. Over time, washers can wear out and cause leaks. Replacing a washer is a relatively simple repair that can be done in a few minutes.
- Turn off the water supply to the faucet.
- Remove the handle by unscrewing the screw that holds it in place.
- Remove the old washer from the valve body.
- Apply a small amount of plumber’s grease to the new washer.
- Insert the new washer into the valve body.
- Reinstall the handle.
- Turn on the water supply and check for leaks.
Tightening O-Rings, How to fix a leaking bathroom sink
O-rings are rubber or plastic seals that create a watertight seal between two surfaces. O-rings can be found in a variety of places in a bathroom sink, including the faucet base, the drain stopper, and the P-trap.
- Turn off the water supply to the faucet.
- Locate the O-ring that is leaking.
- Use a wrench to tighten the O-ring.
- Turn on the water supply and check for leaks.
Fixing Cracked Pipes
Cracked pipes are a more serious problem that can lead to major water damage. If you have a cracked pipe, it is important to repair it as soon as possible.
- Turn off the water supply to the pipe.
- Cut out the cracked section of pipe.
- Install a new section of pipe.
- Turn on the water supply and check for leaks.
Sealing Drain Stoppers
Drain stoppers can leak if the seal between the stopper and the drain is broken. To seal a drain stopper, you can use a variety of methods, including:
- Applying a bead of silicone caulk around the base of the stopper.
- Replacing the O-ring in the stopper.
- Installing a new drain stopper.
Preventative Measures: How To Fix A Leaking Bathroom Sink
Regular maintenance is essential to prevent future leaks. Over-tightening fixtures, using harsh chemicals, and neglecting cleaning can lead to leaks. High-quality materials and professional installation ensure longevity and minimize the risk of leaks.
Maintenance and Cleaning
- Check fixtures regularly for loose connections and tighten them if necessary.
- Use mild cleaning agents to avoid damaging seals and gaskets.
- Clean the sink and drain regularly to remove debris and prevent clogs.
Avoid Over-Tightening
Over-tightening fixtures can damage seals and gaskets, leading to leaks. Use a wrench to tighten fixtures just enough to create a snug fit.
Use High-Quality Materials
High-quality materials, such as brass or stainless steel, are more resistant to corrosion and wear than cheaper materials. They are less likely to develop leaks over time.
Professional Installation
A professional plumber can ensure that fixtures are installed correctly, with proper seals and gaskets. This reduces the risk of leaks and ensures a long-lasting installation.
