Ask Pete: Why Is My Bathroom Sink Draining Slowly?

The Question: Why Is My Bathroom Sink Draining Slowly?

A slow draining bathroom sink is one of the most common calls we get. Other than an overflowing toilet, there are few plumbing issues that are as obvious as that sink full of water — and other stuff. So why is your bathroom sink draining slowly? And what can you do about it?

Pete Says:

If your bathroom sink is draining slowly, it could be caused by a few different things. The most common culprits are clogged pipes, worn-out seals, or corrosion of the drainpipe. To identify and repair the problem, you’ll need to inspect the sink and its components. A professional plumber will check for the following: 

  • Clogs – The most common cause of bathroom sinks draining slowly is clogged pipes. Inspect the sink piping, including the P-trap and drain pipe, to see if there are any physical blockages that need to be removed.
  • Seals – Worn-out seals can prevent water from flowing freely through the bathroom sink. Check the gaskets, seals, and other components to ensure they are still in good condition.
  • Corrosion – Corroded pipes can also lead to bathroom sinks draining slowly. Inspect the drainpipe for signs of rust or corrosion. If necessary, replace any corroded pipes.

By identifying and repairing the cause of a bathroom sink draining slowly, you can ensure that your clients’ sinks are in proper working condition. With these tips, you’ll be able to quickly identify and fix any bathroom plumbing issues.
