How to Unclog a Slow-Draining Bathroom Sink


Clogged or slow-draining bathroom sink is one of the most common plumbing problems. It is usually caused by a buildup of hair, soap, and other debris that can accumulate in the pipes over time. Luckily, it is usually a relatively easy fix that doesn’t require the help of a professional plumber. Here are some tips for unclogging a clogged or slow-draining bathroom sink.

Using a Plunger

The first step is to use a plunger. Fill the sink with enough water to cover the plunger cup, then place the plunger over the drain and pump it up and down several times. This should help loosen any debris that is clogging the drain. If the clog is cleared, run hot water for a few minutes to flush out any remaining debris.

Using a Drain Snake

If the plunger does not work, you can try using a drain snake. A drain snake is a long, flexible metal tool that is used to reach deep into the drain pipe and remove any clogs. Insert the drain snake into the drain until it reaches the clog, then twist and push it down to break up the debris. Once the clog has been cleared, run hot water to flush out any remaining debris.

Using Chemical Drain Cleaners

If the plunger and drain snake do not work, you can try using a chemical drain cleaner. Be sure to read and follow the directions carefully, as some chemical cleaners can be hazardous if used incorrectly. Also, be sure to wear protective gloves and safety glasses when using chemical cleaners. Once the chemical cleaner has been used, run hot water for a few minutes to flush out any remaining debris.

Preventing Clogged or Slow-Draining Sinks

The best way to avoid a clogged or slow-draining sink is to prevent it from happening in the first place. Here are some tips for preventing clogs:

  • Avoid putting grease, coffee grounds, and other solid items down the drain.
  • Clean out the sink strainer regularly.
  • Run hot water down the drain after every use.
  • Install a mesh sink strainer to catch hair and other debris.

If All Else Fails

If none of these methods work, it is time to call a professional plumber. A professional plumber will be able to assess the problem and determine the best course of action. In some cases, the pipes may need to be replaced or the drain may need to be snaked further down the line. Whatever the cause of the clog, a professional plumber will be able to get your bathroom sink draining properly again.
