How to Stop Leaking Bathroom Taps

Leaky bathroom taps can be a frustrating and wasteful problem. Not only do they create an annoying dripping sound, but they also contribute to water waste and can lead to higher water bills and potential plumbing issues. Fortunately, many common types of leaking taps can be fixed with a few simple tools and techniques. This article outlines the common causes of leaking bathroom taps and provides detailed steps on how to repair them.

Identifying the Source of the Leak

The first step in fixing a leaking tap is identifying the source of the leak. This will determine the appropriate repair method. Here are some common types of leaks and their potential causes:

Dripping from the spout: This is often caused by a worn-out washer or O-ring in the tap cartridge.

Dripping from the base of the tap: This may indicate a problem with the faucet's stem or the O-ring that seals the stem to the faucet body.

Constant flow of water: A continuous flow of water indicates a problem with the tap's internal mechanisms, such as a broken valve or worn-out parts.

Leaking when the tap is turned off: This is usually caused by a worn-out washer or O-ring in the tap cartridge.

Fixing a Leaky Tap Cartridge

Many modern bathroom taps utilize a cartridge system, where a single unit contains the valves and seals necessary for controlling water flow. Replacing a worn-out cartridge is often the simplest way to fix a leaking tap.

Tools needed:

Adjustable wrench
Phillips screwdriver
New tap cartridge (compatible with your existing faucet)
Optional: Teflon tape

Steps:

Turn off the water supply: Locate the shut-off valve for your bathroom sink and turn it off. If you cannot find a shut-off valve, turn off the main water supply to your house.
Remove the handle: Use a Phillips screwdriver to remove the screw holding the handle in place. Some handles may also have a decorative cap that needs to be removed first. Gently pull the handle off the tap.
Remove the cartridge: Locate the cartridge retaining nut. Use an adjustable wrench to loosen and remove the nut. The cartridge should then be able to be pulled out of the tap.
Install the new cartridge: Place the new cartridge into the tap body, ensuring it is properly seated.
Reattach the cartridge nut: Tighten the cartridge retaining nut with an adjustable wrench. Be careful not to overtighten, as this can damage the cartridge.
Replace the handle: Reinsert the handle and tighten the screw.
Turn the water back on: Carefully turn the water back on and check for leaks.

Repairing a Leaky Tap Stem

Older bathroom taps often utilize a stem and washer system, where a separate stem controls the water flow and a washer creates a seal to prevent leaks. These types of taps can also leak due to worn-out washers or stems.

Tools needed:

Adjustable wrench
Phillips screwdriver
New tap washer (compatible with your existing faucet)
Optional: Teflon tape

Steps:

Turn off the water supply: Locate the shut-off valve for your bathroom sink and turn it off. If you cannot find a shut-off valve, turn off the main water supply to your house.
Remove the handle: Use a Phillips screwdriver to remove the screw holding the handle in place. Some handles may also have a decorative cap that needs to be removed first. Gently pull the handle off the tap.
Remove the packing nut: Locate the packing nut below the handle. This is a larger nut that is usually either hexagonal or square shaped. Use an adjustable wrench to loosen and remove the packing nut.
Remove the stem: Once the packing nut is removed, the stem should be able to be pulled out of the tap.
Replace the washer: Carefully remove the old washer from the stem. If the stem is also worn, you may need to replace it as well. Install the new washer onto the stem.
Reassemble the tap: Insert the stem back into the tap body. Ensure the stem is properly seated. Replace the packing nut and tighten it securely.
Replace the handle: Reinsert the handle and tighten the screw.
Turn the water back on: Carefully turn the water back on and check for leaks.

Other Common Repairs

In addition to replacing cartridges and washers, there are other repairs that may be necessary to fix a leaking bathroom tap. These include:

Replace the O-ring: Worn-out O-rings can cause leaks at the base of the tap or where the spout connects to the faucet body. You can purchase replacement O-rings from a hardware store.

Tighten the packing nut: If the packing nut is loose, it can allow water to leak past the stem. Tighten the packing nut with an adjustable wrench.

Clean the aerator: Mineral deposits or debris can clog the aerator, causing the tap to leak or spray water unevenly. Remove the aerator from the end of the spout and clean it with a toothbrush and vinegar.

Replace the tap: If the leak is severe or the tap is old and worn, it may be more cost-effective and efficient to simply replace the entire tap.

By carefully identifying the source of the leak and following the appropriate steps, you can fix a leaky bathroom tap and prevent further water waste and damage. If you are unsure how to proceed or lack the necessary tools, it is always recommended to contact a qualified plumber for assistance.
