A blocked external drain is a frustrating problem, often leading to unpleasant backups and potential water damage. Luckily, many blockages can be resolved with simple DIY methods. This guide will walk you through how to unblock your external drain effectively and safely, saving you time and money on expensive plumbers.
Identifying the Problem: What's Causing the Blockage?
Before you begin, it's important to understand the likely culprit. Common causes of external drain blockages include:
- Leaves and Debris: Fallen leaves, twigs, and other garden debris are frequent offenders, particularly in autumn.
- Tree Roots: Intrusive tree roots can grow into drainpipes, causing significant blockages.
- Grease and Oil: Grease and oil poured down the drain can solidify and create a sticky blockage.
- Sand and Sediment: Heavy rains can wash sand and sediment into the drain.
- Toys and Other Objects: Small toys or other objects accidentally dropped into the drain can cause a blockage.
Tools You'll Need:
Gather these essential tools before you start:
- Work Gloves: Protect your hands from dirt and debris.
- Bucket: Collect water and debris.
- Trowel or Spade: To remove debris from the drain opening.
- Drain Cleaning Tool (Plumbing Snake): For reaching deeper blockages. A flexible snake is best for navigating bends in the pipe.
- Garden Hose: For flushing the drain.
- Safety Glasses: Protect your eyes from splashing debris.
Step-by-Step Guide to Unblocking Your External Drain:
1. Clear Visible Debris: Begin by removing any visible debris from the drain opening using your trowel or spade. Dispose of this waste responsibly.
2. Flush with Water: Turn on your garden hose and flush the drain with a strong stream of water. This might dislodge smaller blockages.
3. Use a Drain Cleaning Tool (Plumbing Snake): If the blockage persists, carefully insert a drain cleaning tool (also known as a plumber's snake) into the drain. Slowly feed the snake into the pipe, feeling for resistance. Once you feel resistance, rotate the snake to break up the blockage. Slowly retract the snake, cleaning it off as you go.
4. Flush Again: After using the snake, flush the drain again with your garden hose to clear away any dislodged debris.
5. Inspect Regularly: Prevent future blockages by regularly inspecting and cleaning your external drain, especially after periods of heavy rain or leaf fall. Consider using a drain cover to prevent large debris from entering the drain.
Dealing with Persistent Blockages:
If these steps don't resolve the blockage, the problem might be more serious. You may need to:
- Locate the Drain Cleanout: Most external drains have a cleanout access point. Locating and accessing this point may be necessary for more thorough cleaning.
- Contact a Plumber: For persistent or severe blockages, it's best to contact a qualified plumber. They possess the tools and expertise to handle complex drain problems.
Preventative Measures:
Regular maintenance is key to preventing future external drain blockages. Consider these preventative measures:
- Regular Cleaning: Clean your drain regularly, removing leaves and debris.
- Leaf Guards: Install leaf guards or drain covers to prevent large debris from entering the drain.
- Proper Disposal: Avoid pouring grease, oil, and other substances down the drain.
- Tree Root Management: If tree roots are a recurring problem, consider trimming or removing encroaching roots.
By following these steps and practicing preventative measures, you can keep your external drain flowing freely and avoid costly plumbing repairs. Remember safety first – always wear appropriate safety gear.
