How To Efficiently Remove Scale, Tuberculation, Tree Roots and Descale Pipes With Circular Chains

Restoring optimal flow in sewer lines using circular chains

Descaling pipes is a crucial maintenance task to ensure the smooth operation of plumbing systems. When faced with challenges such as tuberculation and tree roots in pipes, the use of a pipe descaler such as our circular chain combined with a flexible shaft can be highly effective. In this post, we will explore the process of descaling pipes using this method, focusing on how to restore optimal flow. By understanding the importance of employing the appropriate tools for different pipe materials, such as cast iron, clay, and PVC, you can successfully remove scale, tuberculation and debris. Let’s delve into a few details.

Understanding the Role of a Pipe Descaler

A pipe descaler, consisting of a flexible shaft and a circular chain, is a powerful tool used to remove scale, deposits, and obstructions from the inner walls of pipes. The flexible shaft allows for easy insertion into pipes, while the circular chains attached to it effectively clean the entire inner circumference of the pipe, including hard-to-reach areas.

Mastering the Descaling Process

Descaling pipes with a flexible shaft and circular chains requires a systematic approach. Here are the steps to effectively remove scale and address issues such as tree roots in pipes:

1. Assess Drain Pipe Diameter: Before beginning the descaling process, it is essential to determine the drain pipe diameter. This information helps you select the appropriate size of circular chains and ensure an efficient cleaning process. Using chains that are too small or large may not clean the pipe thoroughly or could potentially damage the pipe walls.

2. Selecting the Right Circular Chains: Circular chains are available in different sizes and for different pipe materials. Choose chains that match the drain pipe diameter to ensure proper fit and effective cleaning. Chains without hard bits are suitable for PVC pipes, while circular chains with hard metal bits are meant for cast iron and clay pipes. The chains’ design and construction allow them to scrape away scale and debris, restoring the pipe’s inner surface to its original condition.

3. Clearing Tree Roots in Pipes: Tree roots can infiltrate pipes, causing blockages and reduced flow. To address this issue, start by adding a drill head to your flexible shaft and circular chain. The drill head will remove any bigger, more solid blockages on the way. Once the major obstructions are cleared, the circular chains will remove remaining debris and root remnants.

4. Descaling pipes with a circular chain: Attach the selected circular chain to the drain cleaning flexible shaft and then connect your shaft to a drill. Insert the flexible shaft into the pipe, ensuring it reaches the affected area. Turn the drill on and rotate the shaft with a controlled back-and-forth motion, allowing the chains to clean the entire inner circumference of the pipe. The chains’ movement dislodges lime scale, urine scale deposits, and tuberculation, facilitating their removal.

5. Varying Speed and Pressure: While using the pipe descaler, it is important to vary the speed and pressure based on the severity of the scale and tuberculation buildup. For heavier deposits, a slower rotation speed and higher pressure may be required, while lighter buildup may require a faster speed and lighter pressure. Adjusting these variables ensures optimal cleaning performance.

6. Considering Pipe Material: Different pipe materials, such as cast iron, clay, and PVC, have varying levels of susceptibility to damage. Take into account the specific characteristics of the pipe material when using the pipe descaler. While circular chains are suitable for most materials, it is important to exercise caution and adjust the speed and pressure accordingly to avoid any potential damage.


Descaling pipes using a pipe descaler such as a flexible shaft with circular chains is a highly effective method for removing scale, deposits, and tree roots. By understanding the importance of drain pipe diameter and considering the specific pipe material, such as cast iron, clay, and PVC, you can successfully restore optimal flow and address issues caused by tree roots, scale deposits and tuberculation in pipes.

The circular chains, when attached to the flexible shaft, clean the entire inner circumference of the pipe, ensuring a thorough descaling process. With careful speed and pressure adjustments, the chains scrape away scale and tuberculation, leaving the pipe’s inner surface clean and free from obstructions.

Regular maintenance with a pipe descaler can prevent severe scale buildup and address tree root infiltrations, promoting the longevity and functionality of your plumbing system. By incorporating these practices into your maintenance routine, you can ensure the smooth operation of your pipes and enjoy uninterrupted flow.
