How To Clear Roots From Drain Pipes

Blocked drains are a prevalent problem in many Australian households, and one of the most frustrating causes is root infiltration. Tree roots often find their way into your drain pipes, leading to clogs, backups, and potential damage. Here we will explore practical methods to clear roots from drain pipes, helping you maintain a free-flowing plumbing system and prevent costly repairs.

Identifying Root Intrusion

Identifying root intrusion in drain pipes is crucial for addressing the problem early on. Look out for the signs outlined below, as they can help you determine if tree roots cause your blocked drain pipes and prompt you to take action to prevent further damage.

Slow drainage

One of the most prevalent signs of root intrusion is slow drainage. If your sinks, showers, or toilets are draining slowly or not draining at all, it could indicate a blockage caused by tree roots. The roots restrict water flow through the pipes, leading to backups and poor drainage.

The main sewer line is likely affected if you experience slow drainage in multiple fixtures within your home. This is a cause for concern and requires prompt attention to prevent further damage.

Gurgling noises

Unusual gurgling or bubbling sounds from your plumbing fixtures, such as sinks, toilets, or showers, can indicate root intrusion. When tree roots infiltrate the drain pipes, they create obstructions and air pockets, causing gurgling noises when water flows through the pipes.

If you consistently hear these sounds, especially when using multiple fixtures simultaneously, it's a strong indication that root intrusion is present and affecting the proper functioning of your drainage system.

Foul odours

Foul odours emanating from drains or toilets can be a telltale sign of blocked pipes due to root infiltration. As tree roots grow and accumulate within the drain pipes, they trap organic matter and sewage, releasing unpleasant odours.

If you notice persistent foul smells, especially near drains or toilets, root intrusion is likely causing a blockage and hindering the proper wastewater flow.

Overgrown tree near the drain line

If you have trees or shrubs growing close to your drain line, there is a higher risk of root intrusion. The roots of trees are naturally drawn to sources of moisture, and drain pipes provide an attractive water and nutrient source.

Keep an eye on trees with aggressive root systems, such as willows, poplars, and fig trees, as they are more likely to cause problems. If you notice overgrown roots near your drain line or signs of root damage on the surface, it's essential to take action to prevent further intrusion into your pipes.

Ways To Remove Roots From Your Drains

Here are a couple of methods both DIY and professional that are proven to effectively clear roots from drain pipes:

Mechanical snaking

Mechanical snaking, or drain rodding, is a traditional method to clear root blockages. It involves using a drain snake, a long, flexible metal cable with a corkscrew-like auger at the end. Here's how you can use it:

• Locate the access point: Find the cleanout or access point closest to the affected drain. It's usually a small cap or plug outside the building or in the basement.
• Insert the drain snake: Remove the cap or plug and carefully insert the drain snake into the pipe until you feel resistance.
• Break through the roots: Rotate the drain snake clockwise to break through the roots. Apply steady pressure but avoid excessive force to prevent damaging the pipe.
• Retrieve the snake: Slowly retract the snake while continuing to rotate it to dislodge the roots. Rinse the pipe with water to flush out any remaining debris.

Hydro jetting

Hydro jetting is an effective method for clearing root blockages and is best performed by a professional plumber. It involves using a specialised machine that propels high-pressure water through the pipes to dislodge and flush out the roots.

Here is how it works:

• Locate the access point: Like mechanical snaking, find the access point closest to the affected drain.
• Insert the hydro jetting hose: The plumber will insert a hose with a specialised nozzle into the pipe through the access point.
• High-pressure water jet: The hydro jetting machine delivers a powerful stream of water at high pressure, typically ranging from 1,500 to 4,000 pounds per square inch (psi). The force of the water cuts through the roots, breaks them apart, and flushes them out of the pipe.
• Thorough cleaning: The hydro jetting process removes built-up debris, sediment, and grease from the pipe, leaving it thoroughly cleaned and restored to its optimal flow capacity.

If you attempt this method, use caution and ensure you have the necessary equipment. Rent a high-pressure water jet from a tool rental company and follow the instructions provided.

Chemical root killers

Chemical root killers are another option for clearing roots from drain pipes. They contain herbicides that are designed to kill the roots obstructing the pipes. Here are some important considerations:

• Choose the right product: Select a chemical root killer safe for your plumbing system and follow the manufacturer's instructions carefully.
• Application: Pour the recommended amount of the root killer into the affected drain and let it sit for the specified duration. The chemicals will gradually kill the roots, causing them to decay and disintegrate.
• Flushing the pipes: After the specified time, flush the pipes with water to remove the dead roots and any remaining chemical residue.

It's important to note that chemical root killers should be utilised sparingly and as a last resort. They can harm the environment and, if overused, may damage the plumbing system.

Mechanical cutting

Mechanical cutting involves using specialised tools to physically cut through the roots and remove the blockage. One standard tool used for this purpose is a root saw or a root cutter attachment for drain snakes.

These tools have serrated blades that can cut through the roots and clear the blockage. Mechanical cutting is best left to professional plumbers with the expertise and equipment to safely and effectively perform the task.

Root foaming

Root foaming is another method used to clear roots from drain pipes. Foam root killers are inserted into the pipe; upon contact with water, they expand and coat the pipe's interior.

The foam contains a herbicidal ingredient that kills the roots upon contact. The foam adheres to the pipe walls, providing a longer-lasting effect to inhibit root regrowth. Professional plumbers typically perform this method with access to the specialised equipment needed for proper application.

Homemade root-killing solutions

If you prefer a DIY approach, use a homemade drain cleaning solution to clean your pipes and kill the roots. One popular option is a mixture of rock salt and boiling water.

Dissolve a cup of rock salt in a pot of boiling water and carefully pour it down the affected drain. The high salt concentration can kill roots and hinder their growth. Remember to use caution when working with boiling water.

Safeguard Your Drain Pipes: Preventive Measures

Preventive measures are vital in mitigating the risk of root intrusion in drain pipes. By implementing the methods below, you can proactively protect your plumbing system from costly and disruptive blockages.

Regular maintenance

Scheduling regular drain inspections and maintenance is essential to identify and address root intrusion early. A professional plumber can use specialised cameras to inspect the inside of your pipes, checking for any signs of root infiltration or potential blockages. By identifying the problem early, you can take appropriate measures to prevent further damage and costly repairs.

Root barriers

Installing root barriers near your sewer lines can be a physical deterrent, preventing tree roots from infiltrating the pipes. Root barriers are typically made of materials like plastic or metal and are buried beneath the perimeter of the pipe. These barriers redirect the roots away from the pipes and encourage them to grow in a different direction.

When installing root barriers, it's essential to consult with an arborist or landscaping professional who can advise you on the proper placement and selection of barriers based on the type of trees and the proximity to your sewer lines.

Tree placement

Strategic tree placement is crucial in preventing root intrusion into drain pipes. If you plan to plant trees or shrubs near your property, choose species with non-invasive root systems.

Research the root structures of different plants and select shallow, less aggressive root systems. Planting these trees and shrubs a safe distance away from your drain lines will reduce the risk of root infiltration.

Regular root maintenance

Consider using root maintenance products designed to inhibit root growth within your plumbing system. These products typically contain chemicals that deter root growth without causing harm to the trees themselves.

You can discourage root intrusion and maintain clear drain pipes by periodically applying these products according to the manufacturer's instructions. It's important to note that preventive measures should be implemented in conjunction with regular monitoring and maintenance.

Regularly inspect your drain pipes, particularly if you have trees or shrubs nearby, to ensure there are no signs of root intrusion. If you notice any early signs, take immediate action to prevent further damage.
