The Common Causes of Blocked Drains

There are many common causes of blocked drains in and around the home. These causes range from everyday activities to external factors beyond our control. Some of the most common we see for our clients in Brisbane include:

  • Kitchen sinks being blocked up with grease, oils and other food scraps and kitchen waste.
  • Bathroom sinks and drains are commonly blocked by the accumulation of hair, soap, toothpaste and similar hygiene products.
  • External pipework can be blocked by tree roots, or leaves and vegetation debris.

Identifying and addressing these common causes early on can help prevent the inconvenience and potential damage associated with blocked drains.

Initial Signs Your Drain May Be Blocked

A completely blocked drain will be obvious as the water fills up and does not drain away but how do you identify a partially blocked drain?

  • In the bathroom, slow drainage or water pooling around the shower, sink, or bathtub could indicate a blockage caused by hair, soap scum, or hygiene products.
  • Unusual sounds or gurgling noises while kitchen, laundry or bathroom sinks indicate a potential partial blockage which can get significantly worse if not attended to.
  • Foul or unpleasant odours emanating from kitchen drains indicate foreign objects are stuck in the pipework.

Regularly monitoring and addressing these warning signs can prevent minor blockages from escalating into costly plumbing emergencies.

How a Professional Clears a Drain?

Professional plumbers employ a range of specialized tools and techniques to effectively detect, locate and clear drain blockages to restore proper water flow. These may include electric drain-clearing machines, drain cameras and jet rodders. These tools are both expensive and need an experienced operator to be effective.

By combining expertise with state-of-the-art equipment, experienced and professional plumbers can examine the plumbing system to determine if any underlying issues may be the original cause of the blockage. These external issues commonly include broken pipes which allow tree vegetation into the system, insufficient fall over the line or a sag in the drain. If any of these issues are present, the blockage is likely to reoccur. Once a plumber has identified it issues, they can provide options to fix the fault and provide long term solutions.
