Fact Checked By Daniel Wood | Post Updated On: April 29, 2023

A pressure washer can be converted to a sewer jetter by adding some conversion kits, and it can be used to clean a sewer effectively without giving any trouble.

Can we convert our pressure washer into a sewer jetter?

The answer is yes if you have the appropriate conversion kit and a powerful pressure washing machine. It’s quite obvious to face a blockage in our sewer line that needs to be cleaned with immediate effect to avoid any bigger trouble.

A pressure washer is a machine that takes a regular flow of water inside and generates pressure to make it high-pressure water force. This is the general process, and the high-pressure water can be used to clean any dirt, mold, grease, debris, etc.

You might want to know how to convert a pressure washer into a sewer jetter. The process, which will be described later in this article, is simple and quite effective to clean your sewer.

What is a Sewer Jetter?

Many of us don’t have any idea about a sewer jetter and how it works.

A sewer hydro jetter is a machine to clean the drain inside hard to reach pipes and drainage channels by using high-pressure water. This machine has an engine and a pump to convert the regular water to high-pressure water that comes through a pretty long HP hose and cleans all the obstacles.

How does a Sewer Jetter Work?

At the end of a sewer jetter HP hose, there is a pencil jet spray nozzle attached. Through this nozzle, high-pressure water comes out and cleans all the debris and dirt.

To clean a blocked drain or sewer, you just have to set the right nozzle, start the engine and put it in the sewer pipe. If your hose doesn’t reach the cleaning area, you can attach an extra hose to increase its length.

Difference between Pressure Washer and Sewer Jetter

A pressure washer is a machine that is used to clean a surface such as a patio, fence, vehicle, garage, etc., whereas a sewer jetter is used to clean the sewer pipes and drainage system.

difference between pressure washer and sewer jetter

In a pressure washer, we use different types of nozzles starting from 0-degree to 60-degree, even more. But in sewer jetter, mostly the pencil jet nozzle is used though it has varieties.

You have to hold a spray gun and spray the pressurized water to clean a surface with a pressure washer. But a sewer jetter doesn’t have any spray gun; the nozzle is connected to the end of its HP hose.

The hose is generally longer than a sewer jetter which is reeled to storage for convenient carriage. You will find a frame containing two wheels for moving the machine freely, but you will not get this facility with some sewer.

Can I Use a Pressure Washer as a Sewer Jetter?

A sewer jetter is a similar kind of machine as a pressure washer. As of this question, there are many people who don’t want to spend an extra amount if the work can be done by one machine.

The answer to this question is yes; you can use a pressure washer as a sewer jetter provided you will need some extra components for your pressure washer to make a sewer jetter. The converting process is explained below, and you can easily save plenty of your money.

Necessary Conversion Kits

As stated before, there are some necessary conversion kits you will need to make a sewer jetter out of a pressure washer. The kits might vary depending on your type of work, type of machine and type of drainage system. But, the basic components that you might need are:

  • Jetter Hose
  • Appropriate Nozzle
  • Ball Valves
  • Jumper Hose
  • Hose Reel

Before you start your conversion process, make sure you have bought all of the above-mentioned components. Besides them, you might also need your personal toolbox for connecting or removing the above kits.

How to Convert a Pressure Washer into a Sewer Jetter?

For your easy understanding, the entire conversion process is divided into few steps. You will have to follow the steps to make a sewer jetter out of your pressure washer.

Step 1

We generally remove all the pressure washer components when we are done cleaning any surface and keeping it safely in our storage. At the first step, you have to connect all its components to their right places except the spray gun. Just connect one end of your HP hose to the pressure washer and leave the other open.

Step 2

Now, you have to attach the ball valve to the open end of your HP hose. Try to get a ball valve with a quick connect system that will make your work easy and convenient. The ball valve has a switch that will allow you to on and off your water supply.

Step 3

After attaching one end of your ball valve to the HP hose, you have to connect the other end to your jumper hose. As mentioned before quick connection system will make your work comfortable. You might need some Teflon tape to stop any kind of leaking.

Step 4

At this point, connect the other open end of your jumper hose to the jetter hose. Generally, this hose type is longer than the normal hose and needs to be wrapped on a proper wheel. Make sure that your hose is properly reeled to its storage.

Step 5

Put the nozzle at the tip of your jumper hose, which will go inside your drainage pipe and clear all the obstacles. Using a spray gun is not possible on a jumper hose, and you have to keep it water running all through your cleaning process. You might control the water flow by regulating the switch on the ball valve.

Step 6

Your machine is all set to work, and you have to check if all the components are doing their duty properly. Start the engine, release the water supply and put the jumper hose inside your drainage pipe. Keep on inserting it until all the obstacles and dirt are appropriately cleared. Once your work is done, you take out the hose slowly and before taking the last end out, make sure you stopped the water supply.

By following the above steps, you can easily make an effective and convenient sewer jetter with your pressure washing machine.


The process of converting your pressure washer into a sewer jetter is not very difficult if you have the appropriate conversion kit. To get proper water pressure, you have to keep in mind that you need to have a comparatively powerful pressure washer.

In a sewer jetter, the water needs to travel few hoses, and the combining length is quite long. A lower PSI machine will be able to run through the entire hose and provide a high-pressure washer, which will make your sewer jetter a weak one.

If you look into your budget, you can save a lot of your money by converting your power washing machine into a sewer jetter. You must contact your local expert if you face any kind of problem in the making process.
