What Causes a Blocked Drain?

Before reaching for tools or chemicals, it helps to understand what might be causing the problem. Common culprits include:

• Grease and fat build up from cooking oil and food waste.
  
• Hair and soap residue from showers and sinks.
  
• Wet wipes, sanitary items, or cotton buds that do not break down properly.
  
• Leaves, soil, and debris are blocking outdoor drains.
  
• Tree roots growing into underground pipes.
  

Identifying the likely cause will guide you towards the safest and most effective solution.

Step-by-Step: How to Clear a Blocked Drain Safely

Clearing a blocked drain can often be done with basic household tools and a little patience. Follow these safe DIY steps before calling a professional.

1. Use Boiling Water First

Pouring boiling water slowly down the drain can break down grease or soap deposits. Do this in stages, allowing each pour to work through the blockage before adding more. Avoid this method if you have PVC pipes, as extreme heat may soften the material.

2. Try a Plunger

A traditional plunger is still one of the most effective tools for clearing local blockages. Ensure there is enough water in the basin to cover the rubber cup, press down firmly, and create a seal. Then pump up and down several times to dislodge the blockage.

3. Mix Baking Soda and Vinegar

Pour half a cup of baking soda followed by a cup of vinegar into the drain. The fizzing reaction can help break down organic build-up. Wait 20 to 30 minutes before flushing with boiling water to clear any residue.

4. Use a Drain Snake or Drain Rods

If the blockage is deeper, a drain snake or flexible rod can help reach and remove the debris. Insert the tool gently into the pipe and twist slowly until you feel resistance, then pull back carefully to extract the clog.

5. Check Outdoor Drains

If indoor drains are not the issue, inspect external gullies or inspection chambers. Leaves and debris can easily accumulate here. Wearing gloves, remove the debris and rinse the area with clean water.

When to Call a Professional

DIY methods are suitable for minor blockages, but some signs indicate a more serious issue. Contact a drainage specialist if:

• Water is backing up in multiple fixtures.
  
• You hear gurgling sounds in your pipes.
  
• There is a persistent foul odour.
  
• The blockage returns repeatedly.
  

Coastal Drains offers emergency drain unblocking services 24 hours a day across Sussex. Our trained engineers use professional equipment such as CCTV, drain surveys, and high-pressure jetting to locate and remove even the most stubborn blockages safely.

Professional Methods for Tough Blockages

If DIY techniques fail, professionals use advanced tools to clear and inspect drainage systems effectively.

• Drain Jetting: Powerful water jets remove blockages, fat build-up, and roots from pipes. Learn more about the process in our drain jetting guide.
  
• CCTV Drain Surveys: A small camera is inserted into the drain to identify the exact location and nature of the blockage.
  
• Drain Excavation: Used only when damage is severe and other methods are ineffective.
  

These techniques ensure a long-term fix and prevent further issues.

Preventing Future Blockages

Prevention is always easier than repair. Keep your drains clear with these simple habits:

• Dispose of cooking fats and oils in the bin, not the sink.
  
• Use drain guards in kitchen sinks and showers to catch debris.
  
• Regularly flush drains with hot water.
  
• Schedule routine inspections to catch problems early.
  

You can also explore drain maintenance plans to ensure your system remains in top condition all year round.
