A Comprehensive Guide to Unblock a Drain Outside

When you’re faced with a blocked drain outside your home, the inconvenience and potential for water damage can quickly escalate. Outdoor drainage issues, from a blocked kitchen drain outside to a fully clogged outside drain, require immediate attention. This guide by Burns Plumbing aims to equip you with the knowledge and techniques to tackle even the toughest drain blockage, ensuring your outdoor plumbing remains clear and functional.

Identifying Signs of a Blocked Outside Drain

Identifying the signs of a blocked outside drain is crucial for timely intervention, preventing minor issues from escalating into major plumbing problems. Below are detailed insights into the most common indicators of a drain blockage outside your home:

Standing Water

The accumulation of standing water near an outside drain is a telltale sign of a blockage. This situation arises when the drain cannot facilitate the proper flow of water, causing it to pool in areas outside your home, including near kitchen drains or general area drains. Such standing water not only signifies a serious blockage but also poses risks of water damage and creates a breeding ground for mosquitoes and other pests.

Slow Draining

Experiencing slower than usual drainage outdoors signals a partial blockage in your drainage system. Particularly after periods of heavy rainfall or when attempting to clear debris, water lingering longer than expected is a clear indication that a clog is impeding the normal water flow. This slow drainage often precedes more severe blockages if left unaddressed.

Bad Odours Coming From Your Drainage System

Foul smells emanating from your outdoor drains can indicate trapped debris and stagnant water within the plumbing system, undergoing decomposition. Persistent unpleasant odours near your drains are a distinct sign of a blockage, necessitating immediate attention to remove the offending material and restore fresh air around your property.

Gurgling Sounds

Hearing gurgling or bubbling noises from your drains suggests that air is trapped by a blockage within your plumbing system. Such auditory clues, especially noticeable when water is actively draining, highlight disruptions in the normal flow and function of your outdoor drainage. These sounds can serve as an early warning, prompting further investigation into the health of your drains.

Common Causes of Outdoor Drain Blockage

Here are the most common causes of a blocked outdoor drain:

Leaves and Garden Debris

Autumn brings a natural display of falling leaves, but with it comes the challenge of keeping outdoor drains clear. Leaves, twigs, and other garden debris can accumulate quickly, especially after a storm or during the fall season. This accumulation acts as a plug, hindering water flow and causing water to pool around the blocked drain outside. Regularly clearing your garden and nearby areas of leaves and debris is essential to prevent these materials from entering and clogging your drains.

Mud and Silt Buildup

Drains outside are also susceptible to blockages caused by mud and silt buildup. These sediments can be washed into the drain during heavy rains or can naturally accumulate over time. As mud and silt harden, they create a dense blockage that obstructs water flow. Learning how to clear blocked drains outside filled with mud involves flushing the drain with a pressure hose or employing techniques to dissolve the mud, ensuring the outdoor drainage remains effective.

Blocked Gully Traps

Gully traps serve as a barrier, catching debris before it progresses into the wider sewage system. However, these traps can become overwhelmed with waste, leading to blocked outside drains. Ensuring these gully traps are regularly inspected and cleaned out is crucial for the overall health of your property’s drainage system. This preventative measure helps avoid the unpleasant scenario of water backing up outside your home due to a blocked gully trap.

Incorrect Waste Disposal

One of the leading causes of blocked drains, particularly those connected to kitchen sinks or outdoor cooking areas, is the incorrect disposal of waste. Kitchen fats, oils, and other large debris should never be washed down outside drains, as they can solidify or entangle with other debris, creating significant blockages. Homeowners should practice responsible waste disposal, removing as much waste as manually possible and utilising composting or trash disposal methods instead of relying on outdoor drains to handle all types of waste.

Tools and Techniques to Unblock a Drain Outside

Exploring various tools and techniques is key to effectively unblocking an outdoor drain, from manual efforts to advanced methods:

Manual Removal with Gloves

For minor blockages close to the surface, sometimes all it takes is a pair of gloves. Remove the drain cover and use your hands to pry out debris, such as leaves and twigs, that might be causing an outside drain blockage. This method is often effective for quickly restoring flow to blocked drains outside your home.

Using a Drain Snake

A drain snake, or plumber’s auger, is an essential tool for deeper blockages. To use a drain snake, insert it into the drain and turn it to navigate through the plumbing. As you encounter resistance from the clog, crank the handle to break apart the blockage or hook it to pull it out. This technique is particularly effective for drains outside that have accumulated dense debris or have become clogged with roots.

Hot Water Flush

Pouring boiling water down the drain can help to dissolve fats and oils that might have solidified inside the pipe, contributing to the blockage. This method is simple but effective, especially for kitchen drains outside that may be blocked due to grease or soap residues.

High-Pressure Water Jetting

For more stubborn blockages, such as those caused by mud, silt, or compacted debris in outdoor drainage systems, high-pressure water jetting can be a powerful solution. This technique involves blasting water into the drain at high pressure to break apart the blockage and flush it through the system.

Chemical Drain Cleaners

While chemical drain cleaners should be used sparingly due to their potential to damage pipes and harm the environment, they can be useful for dissolving organic matter inside the drain. Choose a product specifically designed for outdoor use and follow the instructions carefully to avoid any plumbing problems.

Baking Soda and Vinegar

Using baking soda and vinegar to unblock drains is a popular, eco-friendly method that leverages simple household ingredients for effective results. By pouring a mixture of one part baking soda followed by one part vinegar down the clogged drain, the chemical reaction produces a fizzing action that can help break down and dislodge blockages. After letting the mixture sit for an hour, flushing the drain with hot water can clear away the debris, offering a safe and natural way to maintain clear drains without resorting to harsh chemicals.

Preventive Measures to Keep Outdoor Drain Pipes Clear

Adopting preventive measures can significantly enhance the clarity and functionality of your outdoor drain pipes, avoiding common blockages:

  • Regular Cleaning: Regularly clean the drain cover and use a hose to flush water down the drain. This helps prevent debris accumulation and ensures water can flow freely.
  • Install Drain Guards: Cover the drain with guards to trap debris while allowing water to pass through. This simple measure can prevent a lot of material from entering your drains outside.
  • Dispose of Waste Properly: Know how to unblock problems by preventing them. Ensure all waste, especially from the kitchen drain, is disposed of properly and not down the drain.
  • Trim Trees and Bushes: Reduce the chance of blocked outdoor drains caused by leaves and twigs by keeping trees and bushes trimmed away from your drainage system.
  • Regular Inspection: Check drains outside your home periodically for signs of a blocked drain, such as water pooling or bad odours. Early detection can prevent serious outdoor drain blockage issues.
  • Professional Drain Cleaning: Consider scheduling annual or bi-annual cleanings with a professional plumber, especially for complex systems like sewer drains or stormwater drains. Professional cleaning can address not just the symptoms but the root causes of blockages, ensuring your outdoor drainage remains clear and functional.

When to Call a Professional Plumber for Your Blocked Drain

When your own efforts to clear a blocked outdoor drain prove insufficient, it’s time to call in the professionals. Persistent issues like the following require professional help:

  • Recurring Clogs: If you frequently face the same blockage issue despite multiple attempts to clear it, professional insight is needed to address the root cause.
  • Standing Water: Pools of water that fail to drain indicate a severe blockage or a problem deeper within the plumbing system, requiring expert assessment.
  • Sewage Smells: Unpleasant odours emanating from your drain can signify a serious issue in the sewer line, which is best handled by professionals.
  • Complex Blockages: Situations involving the main sewer line or blockages too deep for standard home tools necessitate the equipment and expertise of a professional plumber.
