In this article, we have highlighted the five warning signs of a blocked drain to help understand the situation and identify the plumbing issues immediately.

5 Warning Signs of Blocked Drain


  1. Frequently Blocked Drain

If you notice your kitchen or bathroom drain is blocked frequently, take that as a warning sign of a blocked drain. Such frequent blockages indicate some issues with the main sewer line. Severely blocked drain in the main sewer line will usually occur in multiple drains simultaneously. If you have a frequent blockage in only one drain, it doesn’t indicate severe issues in your sewer line. However, noticing multiple drainage systems clogging at the same time indicates severe blockages issues in the main sewer line. Ensure you call an expert plumber to identify the issue and fix it immediately.

  1. Bad Odour

One of the most common warning signs of a blocked drain is smelling unpleasant odour coming out from your kitchen and bathroom drains. Bad odour can indicate your drain has accumulated stagnant water and decomposed solid waste inside the pipeline which creates a severe blockage. The mixture of gathered still water and rotting solid waste further takes the form of an unpleasant smelling drain. You might notice a bad odour coming out from these common areas – toilets, kitchen sinks, bathrooms, and shower drains. We recommend homeowners not to wait for any visual symptoms and call a professional as soon as possible.

  1. Unusual Sounds

Homeowners can easily detect blocked drain by hearing some unusual sounds coming out from the drain. You might hear some gurgling noise from your toilet or kitchen drains, indicating trapped air in a drainage pipe. It usually occurs due to the build-ups of debris – such as oil, leftover food waste, grease, or soap – inside the drain. When water and air around the blockage collide, it causes the drainpipe to let out gurgling noise. If you hear such unusual sounds from your drain, it’s time to call a plumbing professional who can fix the issues and get it up and running in no time.

  1. Slow Draining

Issues inside your main sewer line can result in minor or severe drainage issues – from clogged lines to slow drainage. If you notice the drainage of your kitchen or toilet sink is slower than usual, consider this as a warning sign of blocked drains. Slow drainage is often caused due to main sewer line blockage. You should get in touch with a plumbing professional for regular checkups and maintenance to prevent slow drainage and other severe issues contributing to a blocked drain.

  1. Sewage Leakage

Noticing sudden wet spots in any area of your home? You might have some drainage issues with your plumbing system. Such occurrence indicates severe sewage leakage. When a sewer line or septic tank line starts to leak, the wastewater immediately reaches the surface of your home or yard and create damp pools. If you notice any wet spots in your house or yard, call an expert immediately.
