As a home or business owner, you must have encountered the nightmare of clogged drains and sewer lines.
If you have, you know that this is not just a mere inconvenience; it can actually pose a significant threat to your property and peace of mind. This is where high pressure water jetting comes to the rescue.
In this article, we will take a closer look at this powerful technique, examining its benefits, applications, and safety considerations, and ultimately assessing its overall effectiveness.
So, without further ado, let’s dive into the world of drain cleaning.

The Effectiveness of Drain Jetting

Drain cleaning is considered to be an essential aspect of maintaining a healthy and functioning drainage system for a home or business. In the past, traditional methods such as snaking and chemical drain cleaners were employed to address blocked drains.
However, these methods are not always effective, and sometimes may even cause more harm than good. High pressure water jetting has powerful jet cleaning nozzles that provide a long-lasting cleaning effect that ensures great results and removes fat, oil, grease, and build-ups of debris, ensuring that the line is free flowing.
Drain jetting is an eco-friendly method as it uses clear water to remove blockages rather than relying on chemicals. It doesn’t use any harsh chemicals that can harm your drainage system or the environment. Instead, it relies on the power of high-pressure water to dislodge and remove all kinds of obstructions from your pipes.
This ensures that your drains are clean and free-flowing, preventing any future clogs and potential damage.
Moreover, drain jetting is versatile and suitable for all types of plumbing systems, regardless of their size, age, or material.
This means that it can be used in residential, commercial, and industrial settings, providing efficient and cost-effective solutions to even the most challenging drain problems.

What is HPW Jetting?

HPW jetting or high pressure water jetting (aka drain jetting), is the top method of removing obstructions from drain pipes and is often chosen by professional engineers.
This process uses specially designed hoses and jetting nozzles which are tethered to high-pressure water pump.
The pump propels water through the hose at an incredible force, effectively breaking down and flushing away debris, grease, and other build-ups that can cause clogged pipes.
The power of sewer jetting comes from the combination of water pressure and water volume. Most high pressure water jetting systems are capable of generating pressures ranging from 1500 psi to 4000 psi, depending on the nozzle size and pump capacity.
This high-pressure water is what shatters solid obstructions, such as tree roots, and dislodges stubborn clogs lodged deep within your pipes.
In addition to breaking down blockages, drain jetting also thoroughly cleans the interior walls of your pipes. This not only restores their full capacity but also extends their lifespan by preventing further build-up and corrosion.
So, in a nutshell, sewer jetting is a powerful and effective technique for drain cleaning that offers long-lasting results.

Benefits of Drain Jetting

  1. Effective and Thorough Cleaning: High pressure water jetting can remove even the toughest blockages, including tree roots, grease build-up, and mineral deposits that traditional methods often struggle to break down. When you combine the high pressures of the water jet with the significant flow rates, drain jetting enables you to achieve a comprehensive clean for your maximum flow rate.

  2. Environmentally Friendly: Unlike chemical drain cleaners, drain jetting does not rely on harmful chemicals that could damage your drainage system and negatively affect the environment. Instead, it uses water, a natural and harmless element, to clean your pipes.

  3. Versatile and Adaptable: Sewer jetting is suitable for a wide range of pipe materials and sizes, making it a flexible solution for residential, commercial, and industrial applications. Its powerful water jets can reach deep into your drainage system, ensuring a thorough cleaning.


How Drain Jetting Works


The pre-inspection stage is vital when it comes to jetting. Your drainage engineer will need to thoroughly check and inspect the drainage system using a CCTV camera. This check shows you the locations of the blockage, determine the cause, and assess the overall condition of your pipes.

Selecting the Right Equipment

Once the pre-inspection is complete, the drainage engineer will choose the appropriate drain jetting equipment for your specific situation. This includes selecting the right water pressure, hose length, and nozzle type to efficiently clear the obstruction and clean your pipes.

Performing the Drain Jetting Process

The drainage engineer will then insert the sewer jetting hose into the pipe and slowly advance it towards the blockage. As the high-pressure water is released from the nozzle, it breaks down and flushes away the obstruction. The process is repeated, if necessary, until the entire pipe is clean and clear.

Advantages of Drain Jetting

HPW jetting provides an extensive list of great benefits for drain cleaning. First and foremost, it is extremely effective at removing even the most stubborn clogs and blockages. The high-pressure water jets are capable of cutting through tree roots, solidified grease, and other hard-to-remove obstructions with ease.
Another significant advantage of HPW jetting is its ability to clean and restore the full capacity of your pipes. The water jets not only dislodge and remove debris but also scour the interior walls of your pipes, eliminating any build-up and corrosion. This helps to prevent future clogs and extends the lifespan of your drainage system.
Lastly, HPW jetting is a fast and efficient process that requires minimal disruption to your daily routine. Professional drainage engineers can complete the job in just a few hours, meaning less time spent worrying about your drains and more time spent on what you do best.

Typical Drain Jetting Applications

  1. Residential Drain Cleaning: High pressure water jetting is an excellent solution for homeowners who are dealing with clogged kitchen sinks, bathroom drains, or main sewer lines. It provides a thorough and long-lasting cleaning that keeps your plumbing system functioning optimally.

  2. Commercial Drain Cleaning: Restaurants, hotels, and other commercial establishments often deal with heavy grease build-up and other debris that can cause blocked drains. Sewer jetting can effectively remove these obstructions, ensuring that your business runs smoothly and without interruption.

  3. Municipal Sewer Cleaning: HPW jetting is also widely used by municipalities to clean and maintain large-scale sewer systems. Its powerful cleaning capabilities make it a cost-effective and efficient solution for keeping public sewer systems in top condition.


Disadvantages of High Pressure Water Jetting

While HPW jetting is undoubtedly a powerful and effective technique for drain cleaning, it does have a few drawbacks.
One of the main disadvantages is that it can be more expensive than traditional methods such as snaking. This is because the equipment and training required for high pressure water jetting are more advanced and specialized.
Another potential downside of HPW jetting is it may not be the right solution for all pipe types. Older, fragile, or corroded pipes may be at risk of damage from the high-pressure water.
However, a professional plumber will be able to assess the condition of your pipes during the pre-inspection process and determine if drain jetting is the right solution for your situation.
Lastly, while HPW jetting is an environmentally friendly method for drain cleaning, it does consume a significant amount of water. This may be a concern in areas with water restrictions or where water conservation is a priority.

What Do I Need To Consider For Safety With HPW Jetting?

Drain jetting is a powerful technique that can pose certain risks if not performed correctly. Before attempting HPW jetting, it is essential to consider the following safety measures:
