Bathroom Sink Leaking at Water Supply Line: A Comprehensive Guide

A leaky bathroom sink can be a frustrating and inconvenient problem. Not only can it waste water, but it can also lead to water damage and mold growth. If you're experiencing a leak at the water supply line, it's important to fix it as soon as possible.

There are a few different reasons why a water supply line might leak. The most common cause is a loose or damaged connection. Over time, the connections between the water supply line and the faucet or sink can loosen due to vibration or wear and tear. This can create a gap that allows water to escape.

Another common cause of leaks is a damaged or worn-out washer. Washers are small, rubber discs that create a seal between the faucet and the water supply line. When a washer is damaged or worn out, it can no longer create an effective seal, allowing water to leak out.

In some cases, a leak at the water supply line may be caused by a more serious problem, such as a crack in the pipe or a faulty faucet. If you're not sure what's causing the leak, it's best to call a plumber for assistance.

How to Fix a Bathroom Sink Leaking at the Water Supply Line

If you're confident in your DIY skills, you can try to fix a bathroom sink leak at the water supply line yourself. Here are the steps:

  1. Turn off the water supply to the sink.
  2. Disconnect the water supply lines from the faucet. Use a wrench to loosen the nuts that hold the lines in place. Be careful not to overtighten the nuts, as this can damage the lines.
  3. Inspect the washers. If the washers are damaged or worn out, replace them with new ones. Make sure that the new washers are the correct size and type for your faucet.
  4. Reconnect the water supply lines to the faucet. Hand-tighten the nuts until they are snug. Do not overtighten the nuts.
  5. Turn on the water supply and check for leaks. If there are no leaks, you have successfully fixed the leak.

Prevention

There are a few things you can do to prevent leaks at the water supply line:

  • Inspect the water supply lines regularly for any signs of damage or wear and tear.
  • Tighten the nuts on the water supply lines every few months to ensure that they are snug.
  • Replace the washers in the faucet every few years, or more often if they show signs of wear and tear.

By following these tips, you can help to prevent leaks at the water supply line and keep your bathroom sink in good condition.
