Common Reasons Your Sink Drains Water Slower than Usual

Is your sink draining slower than usual? This can be inconvenient as tasks such as doing the dishes or bathing may take twice the time they usually do. However, beyond these inconveniences, a slow draining sink may be an indication of more severe problems, such as blocked drains or problems with your septic tank.

This article will run you through the possible causes of your slow-draining sink and how you can solve them.

Common Causes of Slow-Draining Sinks

Any of the following may cause problems with your sink draining:

  • Minor Blockage: Hair, dirt, food, and soap scum can clog your pipes. A plumber will inspect your pipes with a camera to see the blockage. They will then remove the blockage and clean the line.
  • Tree Roots in Your Pipes: Tree roots can grow in your sewer line and damage your pipes. There is no way to prevent this issue, but a plumber can remove the tree roots and replace the damaged pipe section.
  • A Clogged P-Trap: The P-trap is directly under your sink. As it is bent in shape, grease and other materials can accumulate in the bend of this pipe.
  • Sludge in Your Septic Tank: Sludge collecting in your septic tank can block up the mainline and cause slow-draining sinks. A plumber will need to diagnose this issue and clean up your tank.
  • Problems in Your Drain Pipes: Drainpipes connect directly to the main sewer line, but they can also have leaks, clogs, sediment buildup, and other issues.
  • Problems in Your Vent Pipes: Vent pipes allow air to travel through the drain pipes. This forms a vacuum to create air pressure and eliminate gasses that cause unpleasant odours. Unbalanced air pressure due to blocked vent pipes can cause your sink to drain slowly.  
  • Deteriorated or Old Plumbing: If you regularly flush chemical cleaners down your drain, your pipes may get corroded and deteriorate. You may also have deteriorated plumbing due to its old age. Your plumbing may need to be replaced with new ones in these cases.

What Happens If You Leave Your Drain Clogged?

A slow-draining drain may not be a severe problem. However, leaving the problem unattended for an extended period can lead to more severe issues, such as:

  • Mould and Mildew in Damp Spaces: If you have a slow-draining sink, the water stagnates in the sink and causes mould growth. These microorganisms are not only unattractive but may also cause health problems.
  • The Buildup of Soap Scum: Soap scum is caused by soap and other products that you regularly use, such as shower gel and toothpaste. 

If you leave a slow-draining sink unattended, the soap scum and other residues in the sink will accumulate and harden. This will result in clogs that are harder to remove the longer they stay in the sink.

  • Unpleasant Odours: Unpleasant odours are emitted from your sink as it drains slowly. These gasses can be harmful to your health if they build up in enclosed spaces. If left unchecked, these odours will eventually spread to other rooms in the house.

Conclusion

A slow-draining sink can be a minor inconvenience or indicate a more severe plumbing issue. In either case, you should get regular drain inspections and clean your sink drains regularly.
