Bathroom Sink Mixer Tap Dripping Water Inside

Bathroom Sink Mixer Tap Dripping Water Inside: Causes and Solutions

A dripping bathroom sink mixer tap can be a frustrating and potentially costly problem. Not only can it waste water and increase your water bills, but it can also damage your bathroom fixtures and surrounding areas over time. If you find yourself dealing with a leaky faucet, it's important to take action as soon as possible to prevent further damage and save money.

There are several common causes of a bathroom sink mixer tap dripping water inside. Understanding these causes can help you identify the problem and find the appropriate solution:

Worn-out washer: The washer is a small rubber or plastic disk that creates a seal between the tap spout and the valve stem. Over time, the washer can become worn or damaged, causing leaks.
Damaged O-rings: O-rings are small rubber gaskets that create seals in various parts of the tap. If an O-ring becomes worn, cracked, or damaged, it can cause leaks.
Faulty cartridge: The cartridge is a cylindrical-shaped component that controls the flow of water through the tap. A faulty cartridge can cause leaks if it becomes worn, damaged, or clogged.
Loose connections: Loose connections between the tap body and the water lines can cause leaks. This can occur due to improper installation or over time as the connections loosen.
Damaged aerator: The aerator is a small screen attached to the end of the tap spout. It helps mix air with water, creating a more even flow and reducing splashing. A damaged or clogged aerator can cause leaks.

Once you've identified the cause of the leak, you can take steps to fix it:

Replace worn-out washers: If the leak is caused by a worn-out washer, you can replace it with a new one. Make sure to use the correct size and type of washer for your tap.
Replace damaged O-rings: If the leak is caused by damaged O-rings, you can replace them with new ones. Make sure to use the correct size and type of O-ring for your tap.
Replace the cartridge: If the leak is caused by a faulty cartridge, you'll need to replace it with a new one. This can be a more complex repair, so it's best to call a plumber if you're not comfortable doing it yourself.
Tighten loose connections: If the leak is caused by loose connections, you can tighten them using a wrench. Make sure not to overtighten the connections, as this could damage the tap.
Clean or replace the aerator: If the leak is caused by a damaged or clogged aerator, you can clean or replace it. To clean the aerator, remove it from the tap spout and soak it in a solution of vinegar and water. If the aerator is damaged, you'll need to replace it with a new one.

In some cases, you may need to call a plumber to fix a leaking bathroom sink mixer tap. This is especially true if the leak is caused by a faulty cartridge or if you're not comfortable making repairs yourself. A qualified plumber can diagnose the problem and make the necessary repairs quickly and efficiently.

By understanding the causes of a bathroom sink mixer tap dripping water inside and taking steps to fix the problem promptly, you can save money, prevent damage, and keep your bathroom looking its best.
