What Is Hydro Jetting?

If you’ve ever had a tree root extracted from your sewer line, then you know how frustrating a blockage in your pipes that cause backups of water in your yard or home can be. Learn more about what this tool is used for and how it sets itself apart from a simple snake. 

What is Hydro Jetting?  


Hydro jetting is an effective method of cleaning drains and main sewer lines. A jetter for sewer lines has a water storage tank and hose attachment that will blast water into the drain lines with 4,000 PSI / 18 gallons per minute or greater. A professional contractor will use specialty jetting nozzles which will vary depending on the type of clog, size of the drain, and level of build-up in the drain/pipe. Specialty nozzles can redirect the spray of the high-pressure water to cut through even the heaviest tree roots and scale build-up, fully removing it from the pipeline.  

 What Exactly is it  Used For? 

This is used to completely eliminate scale build-up and heavy root intrusion in the main sewer line, and heavy grease and scale build-up. If you’re noticing recurring clogs in your home’s plumbing system, it’s time to call a reputable professional to the scene. In many cases, clogged drains and problems with water pressure indicate more serious problems inside the plumbing pipes. An expert should know the best course of action to take, and when to implement hydro jetting as a solution.

What is the Difference Between a Pressure Washer & Hydro Jetter?


Are they the same? Initially, yes, they have the same features, but they are not the same in comparison. However, when it comes to the pressure used, a pressure washer normally expels 2.5 – 4 gallons per minute while a trailer-mounted hydro jetter uses anywhere between 18 – 25 gallons per minute. 

Jetters and pressure washers alike both come with a pump, engine, and some form of pressure control (usually an unloader valve). In most cases, that’s where the similarity ends. A professional jetter will have additional features like a pressure gauge to aid in making adjustments, a pulsation valve to create hose shake when needed, a hose reel with an adequate continuous length of jetting hose, multiple jetting nozzles, and a method of turning the flow to the nozzle on and off. Larger units will include a water tank to supply both the right amount of incoming water for the unit and to provide for cooling of the pump for longer periods in bypass (flow is turned off with a valve but the engine is running). A jetter is built specifically to do the job.

 When is it Necessary to Preform Hydro Jetting?


Typically, hydro jetting of the main sewer line is not the first step to clear a clogged drain line.  Here are examples to when hydro jetting is necessary:

  • Heavy clogs that won’t clear by snaking.
  • Backflow of water and sewage into the drains of your home. 
  • Area drains overflowing in the rain. 
  • In preparation for epoxy relining.
  • Commercial preventative maintenance. 

An Inside Look


Accessing a cleanout, an area of the plumbing system that allows a professional to easily gain access to the pipes, an expert inserts a hose that is connected to a tank of water. This hose and its many attachments can withstand the high-pressured water that expels into the pipes. The process of removing build-up involves working with gravity. The majority of home plumbing systems use gravity to pull wastewater out of the time and into the local sewer system. The hydro jetter works from the bottom up. Inserted into the downstream portion of the system. It moves upstream, working its way through the system. As water scours the pipes, the debris that is dislodged then moves down, with gravity, safely flushing the debris out of the system. A jetter normally also has camera technology to inspect the pipes while they are being cleared, making it much easier to diagnose an issue. 

Hydrojet Cleaning



In almost all cases, hydro jetting is a safe way to remove blockages that cause clogging. However, it is possible to cause further problems. If tree root infiltration has led to pipe damage or compromised the pipe’s waterproof coating, hydro jetting will not solve the problem, and can even lead to more problems. That is why you should always work with a professional who will visually inspect your exterior pipes using video camera equipment to assess the main cause of the problem before implementing any solution, that way no party is wasting their time or resources.

If you are experiencing problems with your plumbing system, work with an experienced and knowledgeable professional. Using diagnostic tools, hydro jetting allows experts to accurately and effectively clean debris out from the pipe system and sewer lines.
