Blocked outside drains are a common issue that can cause significant inconvenience and potential damage to your property if not addressed promptly, especially when dealing with a blocked drain. Understanding the causes, identifying who is responsible, and knowing how to tackle the problem effectively are crucial steps in maintaining a healthy drainage system. This guide will walk you through everything you need to know about unblocking outside drains, from identifying the problem to preventing future blockages.
Understanding Blocked Outside Drains
Blocked outside drains, or external drains, can occur for various reasons, each contributing to the obstruction in different ways. Knowing the common causes can help you prevent and address these issues more effectively.
What Causes Blocked Outside Drains?
Leaves and Debris Accumulating in the Drain: Leaves, twigs, and other garden debris can easily enter and clog outside drains, especially during autumn.
Fat and Grease Buildup from Kitchen Waste: Fat and grease can solidify and stick to the inside of pipes, gradually building up and causing blockages.
Tree Roots Growing into the Drain: Roots can infiltrate and grow inside drains, leading to significant blockages and damage.
Flushing Solid Items Down the Drain: Items such as sanitary products, wet wipes, and other non-degradable materials can cause severe blockages.
Sediment and Waste Accumulating in the Drain: Over time, sediment, soil, and other waste can accumulate and obstruct the flow of water. A drain blocked with mud and silt can indicate larger problems like broken pipes. Removing the debris by hand and using tools like drain rods and hoses is essential for effective clearing.
Common Types of Outside Drain Blockages
Hair and Soap Scum Buildup: Hair and soap scum from bathroom drains can combine and cause blockages in outside pipes.
Food Waste and Grease Accumulation: Kitchen waste such as food scraps and grease can solidify and block drains.
Tree Roots and Debris: Tree roots and natural debris are common culprits in outdoor drain blockages.
Mud and Silt Buildup: Mud, silt, and other sediments can accumulate in drains, particularly after heavy rain.
Lateral Drains: Lateral drains serve as conduits for wastewater leading to the main sewerage systems. Local water companies are responsible for maintaining them, especially in cases of blockage or when determining who handles drainage issues.
Identifying Responsibility for Blocked Drains
Understanding who is responsible for maintaining and unblocking drains is essential to resolving the issue effectively. Drain covers play a crucial role in preventing blockages and are a key part of maintenance responsibility, as they protect drains from debris and other potential blockages.
Who Is Responsible for Blocked Drains Outside?
Homeowners: Generally, homeowners are responsible for internal drains and any drains within the boundaries of their property.
Local Water Companies: External drains and public sewer systems are typically maintained by local water companies.
Shared Drains: Drains that are shared between multiple properties may be the responsibility of the homeowners or the local water company, depending on local regulations.
Preparing to Unblock the Drain
Before you begin unblocking your drain, gather the necessary tools and take appropriate safety measures.
Tools and Equipment Needed
Drain Rods or Plumber’s Auger: Essential for breaking up and removing blockages. Drain rods are particularly effective as they can be connected to reach deeper obstructions and come with different end fittings to tackle specific blockages.
Protective Clothing and Gloves: To protect yourself from contaminants.
Bucket and Bin Bags: For collecting debris and waste.
Pressure Hose or Garden Hose: Useful for flushing out debris.
Drain Cleaning Products (Optional): Chemical cleaners can help dissolve stubborn blockages, but use with caution.
Removing the Drain Cover
Use a Screwdriver: Insert a screwdriver into the edges of the drain cover to pry it off.
Be Careful: Ensure the cover does not fall into the drain, as retrieving it can be challenging.
DIY Methods for Unblocking Outside Drains
Several methods can be used to clear blocked outside drains. Choose the method that best suits your situation.
It is also important to maintain outdoor drains after clearing blockages to prevent future issues.
Using a Drain Rod to Clear Blockages
Feed the Drain Rod into the Drain: Insert the rod into the drain and push it towards the blockage.
Twist and Push: Twist the rod to break up the blockage and push the debris out.
Use a Drain Rod Insert: For blockages further down the drain, attach an insert to reach deeper.
Alternative Methods for Unblocking Outside Drains
Boiling Water and Bicarbonate of Soda: Pour boiling water and bicarbonate of soda into the drain to help dissolve grease and debris.
Chemical Drain Cleaners: Use with caution, as harsh chemicals can damage pipes and harm the environment.
Pressure Hose: Attach a pressure hose to flush out debris with high-pressure water.
Dealing with Standing Water
Standing water can make the unblocking process more challenging. Here’s how to handle it effectively.
What to Do If There’s Standing Water
Remove Standing Water: Use a bucket or wet vacuum to remove as much water as possible before attempting to clear the blockage.
Avoid Splashing: Be careful not to splash water, as it can spread contaminants and worsen the situation.
Protecting Yourself and Your Property
Safety should always be a priority when unblocking drains. Follow these precautions to protect yourself and your property.
