Tips for maintaining your sewer better and getting the most out of it

At some point, we, all the adults, find ourselves in a position where the drainage system gets blocked and doesn’t flow like usual. That causes dirty water to take over our place.

And let’s be honest – We all procrastinate on the task of cleaning our piping system because we don’t want to spend a ton of money on buying a full-fledged sewer jetter, and it’s tiresome to clean a blocked drain without a sewer jetter.

But pressure washers could help. Did you know that you could convert the pressure washer you already have and use it as a sewer jetter?

In this article, I will show you How To Convert A Pressure Washer Into A Sewer Jetter

Let’s get started!

Before we get into the process, if you know exactly what a sewer jetter is and how it works. Then you’d be able to understand the process easily.

A Sewer hydro jetter is a drain cleaning machine that uses high-pressure water to clean through the obstacles in a drainage channel. The core of a sewer jet is its high-power pump that creates water pressure.

Nozzles are also crucial for a sewer jet as various nozzles utilize the pressure differently and serve a different purposes. Other components of a sewer jetter include a given length of hose, a hose reel, and a water tank (optional).

Some large jetter includes a dedicated water tank, whereas others utilize nearby water sources.

When you have to clean a blocked drain or pipe with it, you just set the right nozzle and insert the hose in the drain or sewer, then turn the motor on and let the high-pressure water clean through the obstacles.

Pressure Washers Vs. Sewer Jetters

Many people will quickly assume that the two machines are the same as they both utilize pressure. However, they are quite different.

The following are some of the key differences between these two:


The most common pressure washer has a flow rate of 2.5 to 4 GPM (GPM). Sewer jetters begin at the 4 GPM mark and continue to rise. Portable machines commonly operate at 8 to 9 GPM, while trailer-mounted ones may reach 25 GPM.


Most pressure washers have 1,500 to 3,000 PSI (pounds per square inch). However, sewer jetters offer around 1500 PSI in general, which may go up to 5000 PSI. The increased pressure helps to clear away the most stubborn clogs.


The hose length on a pressure washer is generally around 25 feet. On the other hand, sewer jetters have 50 to 300 feet of hose. It allows you to reach the clog without moving the machine around too much.

Sewer jetters have lightweight hoses that you may readily insert into a pipe.


The nozzle on a pressure washer is wide to provide even coverage. Sewer jetter nozzles, however, are designed to enter the drain pipe. These nozzles are also much smaller to concentrate the water pressure into a small area to help remove the clog more effectively.

Is It Possible To Use A Pressure Washer As A Sewer Jetter?

Yes, a pressure washer can be used as a sewer jetter! A sewer jetter used by a contractor is required, just a high-pressure pump and a long hose with a specific nozzle shape. As a result, doing the pipe cleaning yourself is quite simple; you only need a pressure washer attachment.

However, remember that professional sewer jetters come with a strong high-pressure pump. Most of cases, your residential pressure washer will not be powerful enough to do the job right. In addition, a sewer jetter nozzle is different from a pressure washer nozzle, so make sure you get the right one!

If you’re unsure what kind of equipment is ideal for your situation, use this guideline as a starting point. As a general rule, you’ll want a machine that produces approximately 2 GPM and at least 2,000 PSI. Otherwise, expect to spend most of the day cleaning clogged drainage pipes.

According to Amazon, the most conversion kits available on the site can handle up to 4,000 PSI, which can suit almost all of our electric pressure washer models and many non-commercial gas pressure washers.

How To Convert A Pressure Washer Into A Sewer Jetter?

Let me assure you, in the first place – it’s one of the most straightforward tasks ever. But it would be best if you were cautious about some little things I’m going to discuss as I carry on.

The first thing you need to do in this process spends some money. Yes, it’s not free, but not as expensive as buying a jetter itself. So be ready to spend around 300 bucks that you will buy a conversion kit.

You’ll find many online stores, including Amazon, that sell the sewer jetter conversion kit. But, of course, you’ll find those in your local shops too – they’re quite straightforward tools.

This kit typically includes five things :

  1. Ball Valves
  2. Jumper Hose
  3. Hose Reel with Hand Carry 
  4. Jetter Hose
  5. Nozzles (Ram, Laser & Rotary)

The price of the kit may vary depending on the length of the jetter hose you want. You can also buy cheaper variants if you wish to, but that will not include the hose reel with a hand carry tool and the jumper hose.

It will also function properly, but in that case, you’ll have to deal with the jetter hose by hand and connect it directly to the ball valves. You’ll, later on, understand what I’m talking about.

After you’ve brought your kit home, this is what you’ll have to do:

Step 1: Attach your ‘high-pressure’ water hose to the output of your pressure washer.

Step 2: Replace the spray gun of your pressure washer hose with the ball valve that comes with the conversion kit.

Step 3: Take the jumper hose, and connect one end with the ball valve and another with the jetter hose. It’ll be easier if you already wrap the jetter hose around the hose reel and install the reel onto the hand carry.

Step 4: Put your desired nozzle on the other end of the jetter hose.

Step 5: Make sure every connection is gentle and firm so there aren’t any leaks.

And you’re done. Get started with your cleaning job now.

Utilize your hose reel to reach the piping system’s deepest part. Take the reel close to the opening of the piping system and then release the hose as much needed so that the nozzle reaches close to the blocked area. That way, it’ll clean better. Keep moving forward in this process to reach the deepest part of the system.

However, note that not all the conversion kits can bear all sorts of water pressure. The standard conversion kits can usually bear up to 4000 PSI. If you have to go further, look for a compatible conversion kit.

How To Use A Sewer Jetter?

If you are new to using a sewer jetter, there are some things you should know before operating one. 

  1. First, wear protective clothing, such as goggles, work pants, and boots. That is to prevent any injuries from the high pressure of the sewer jetter. 
  2. Second, be sure to read the manual before operating. It will ensure that you are using the jetter correctly and safely. 
  3. Third, check the nozzle body for any damage before starting. If there are any cracks or worn threads, replace the nozzle. 
  4. Fourth, use thread sealant on the nozzle to prevent leaks. 
  5. Fifth, insert the nozzle into the sewer line before turning on the pressure. Ensure the nozzle is inserted far enough into the line so that any backward-facing jets will not harm the employee.
  6. Sixth, always depressurize the system before removing the nozzle. Put a mark on the last 15 inches of the hose to know where the nozzle is. This way, you will know how close the nozzle is to the entry as you finish cleaning. 

Following these simple steps, you can safely and correctly operate a sewer jetter.

  1. Brett,
    Thank you so much for a very clear explanatory video. You obviously put some effort into the production because it proceeds so smoothly. Videos, like athletic feats & dramatic performances, that look like “no sweat” normally involve LOTS of thought and work. Thanks for making the time and the effort!!!

  2. I don’t understand the answer that I “should put much pressure” on an old pipe…

    Could you explain what you mean, please? Thank you.
