What is Hydro Jetting?

Hydro jetting is a specialized plumbing procedure that involves the use of high-pressure water to clean and clear sewer lines and drains. Unlike traditional snaking methods that may only punch a hole through a clog, hydro jetting thoroughly cleans the interior of pipes, removing buildup and residue that can lead to recurring blockages.

How Does Hydro Jetting Work?

The process of hydro jetting begins with a professional plumber deploying a specialized tool called a jetter. This equipment consists of a tank that holds water, a high-pressure hose, a specially designed nozzle, and a mechanism to pressurize the water for release. The plumber inserts the jetter into the sewer line through an access point, such as a cleanout opening, and activates the system.

Once activated, the high-pressure water is propelled through the hose and out of the nozzle at pressures reaching up to 3,500 pounds per square inch (psi). This intense force allows the water to scour the interior walls of the pipe, dislodging debris, grease, scale, and other obstructions in its path.

Different types of nozzles are available for various applications; for instance, chisel-type nozzles are effective for cutting through tough blockages like tree roots or hardened sediment.

Benefits of Hydro Jetting

  • Thorough Cleaning: Hydro jetting provides a comprehensive cleaning solution by removing buildup along the entire length of the pipe.
  • Environmentally Friendly: As it relies solely on water pressure for cleaning, hydro jetting is an eco-friendly option that does not involve harsh chemicals.
  • Long-Term Results: By clearing out debris completely, hydro jetting helps prevent future clogs and promotes better drainage.
  • Versatility: Hydro jetting can be used in various types of pipes and is effective for both residential and commercial plumbing systems.

When to Consider Hydro Jetting

Hydro jetting is an ideal solution for addressing persistent clogs or slow drains caused by:

  • Grease buildup
  • Soap scum accumulation
  • Mineral deposits
  • Tree root infiltration
  • Scale formation

However, it is essential to note that hydro jetting may not be suitable for all situations. Older or fragile pipes may be damaged by the high-pressure water, leading to potential leaks or ruptures. Additionally, if a pipe is already compromised due to cracks or breaks, hydro jetting may exacerbate the issue.

Professional Hydro Jetting vs. DIY Solutions

While there are DIY hydro jetting kits available on the market, it is highly recommended to enlist the services of a professional plumber for this task. Professional plumbers have the expertise and equipment necessary to perform hydro jetting safely and effectively without causing damage to your plumbing system.


In conclusion, hydro jetting is a powerful tool in the arsenal of modern plumbing techniques. By harnessing the force of high-pressure water, hydro jetting can tackle even the toughest clogs and restore optimal flow to your sewer lines. Whether you are dealing with stubborn blockages or seeking preventive maintenance for your plumbing system, hydro jetting offers a thorough and environmentally friendly solution.

Remember to consult with a licensed plumber to determine if hydro jetting is suitable for your specific situation. With proper care and maintenance, your plumbing system can remain free from obstructions and function efficiently for years to come.
