Top Drainage Tips

Blocked drains are a common household nuisance that can lead to unpleasant odours, slow drainage, and even more serious plumbing issues if left unaddressed. Understanding the common causes of blocked drains is the first step in preventing them. In this article, we’ll explore the top 10 things that can cause blocked drains and discuss ways to avoid these issues.

  1. Hair Buildup: Hair is one of the primary culprits behind blocked drains. Over time, hair strands can accumulate in the pipes, forming clogs that impede water flow. Use drain guards or screens to catch hair and regularly clean them to prevent blockages.
  2. Grease and Oil: Pouring grease and cooking oil down the drain may seem convenient, but it can lead to serious blockages. These substances solidify as they cool, coating the pipes and attracting other debris. Dispose of grease in a separate container and throw it in the trash.
  3. Soap Scum: Soap scum is a sticky residue that can accumulate in pipes over time. It combines with other substances, creating a stubborn blockage. Consider using soap-free cleansers or installing a water softener to reduce soap scum buildup.
  4. Food Waste: Avoid putting food scraps, coffee grounds, and other kitchen waste down the sink. Use a strainer in the kitchen sink to catch solid particles and dispose of them in the trash.
  5. Foreign Objects: Small objects like toys, jewellery, and toiletry items can accidentally find their way into drains, causing blockages. Keep an eye on what goes down the drain, especially in households with children, and use drain covers to prevent foreign objects from entering.
  6. Toilet Paper and Sanitary Products: Flushing excessive amounts of toilet paper, baby wipes, and sanitary products down the toilet can lead to toilet blockages. Only flush toilet paper, and use a trash can for other sanitary items.
  7. Tree Roots: Tree roots seeking water can infiltrate underground pipes, causing blockages and structural damage. Regularly inspect and maintain your outdoor plumbing to detect and address root intrusions early.
  8. Mineral Buildup: Hard water can lead to mineral deposits accumulating in pipes, reducing water flow. Install a water softener to prevent mineral buildup and extend the life of your plumbing system.
  9. Deteriorating Pipes: Aging or deteriorating pipes can collapse or develop cracks, leading to blockages. Regularly inspect your plumbing system, and if you notice any issues, consult a professional plumber to address them promptly.
  10. Lack of Regular Maintenance: Neglecting regular maintenance is a common reason for blocked drains. Schedule routine inspections, cleanings, and repairs to keep your plumbing system in optimal condition and prevent blockages before they become major problems.


By being mindful of what goes down your drains and implementing preventative measures, you can significantly reduce the risk of blocked drains. Regular maintenance, proper disposal practices, and the use of protective devices will help keep your plumbing system running smoothly, saving you time, money, and the inconvenience of dealing with blocked drains.
