Blocked drains are one of the most common plumbing issues that homeowners in Melbourne encounter. While they can be a frustrating inconvenience, understanding the underlying causes of blocked drains can help you take proactive measures to prevent them. In this article, we’ll delve into the top 5 reasons why your drains might be blocked and provide valuable insights to keep your plumbing flowing smoothly.

  1. Food Debris and Grease Buildup

Your kitchen sink can easily become a hub for food scraps, coffee grounds, and cooking oils. Over time, these substances accumulate, leading to clogged drains. Grease, in particular, can solidify and stick to the pipe walls, causing a stubborn blockage. To prevent this, use sink strainers to catch food particles and dispose of grease properly, rather than pouring it down the drain.

  1. Hair and Soap Scum Accumulation

Bathroom drains are prone to blockages due to hair, soap scum, and personal care products that go down the drain. Hair can wrap around pipe bends and trap other debris, forming a tight blockage. Regularly cleaning your drains, using hair catchers, and minimizing the use of bar soaps can help reduce the risk of blockages.

  1. Foreign Objects and Non-Flushable Items

Children’s toys, sanitary products, and wet wipes are examples of non-flushable items that often find their way into toilets and drains. These items can obstruct the pipes and lead to blockages that are difficult to clear. It’s important to educate your household about what can and cannot be flushed or washed down the drain.

  1. Tree Root Intrusion

Beautiful trees and gardens can also be a source of blocked drains. Tree roots are attracted to the moisture and nutrients inside pipes, and over time, they can infiltrate and obstruct the flow of wastewater. If you have trees near your plumbing lines, consider regular root maintenance and inspections to prevent root intrusion.

  1. Broken or Collapsed Pipes

Age, corrosion, and ground shifts can lead to cracked, broken, or collapsed pipes. These damaged pipes can catch debris, causing blockages. Additionally, offset or misaligned pipes can create areas where debris accumulates, leading to blockages over time. If you suspect damaged pipes, it’s essential to seek professional assistance to assess and repair the issue.

Preventive Measures

Prevention is key to avoiding the hassle and expense of blocked drains. Here are some preventive measures you can take:

  • Use drain screens or strainers to catch debris before it enters the drain.
  • Avoid pouring grease, oil, and coffee grounds down the sink.
  • Dispose of non-flushable items properly in the trash.
  • Regularly clean bathroom drains by removing hair and soap scum.
  • Consider periodic professional drain cleaning to keep your pipes clear.
