How To Convert A Pressure Washer Into A Sewer Jetter: How and Why!

At some point, we, all the adults, find ourselves in a position where the drainage system gets blocked and doesn’t flow like usual. This 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 into 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 that you already have and use it as a sewer jetter?

In this article, I’m going to show you How To Convert A Pressure Washer Into A Sewer Jetter! Let’s get started!

What Is a Sewer Jetter? How does it work?

Before we get into the process, if you have the know-how of what exactly is a sewer jetter and how it works, 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 the water pressure.

Nozzles are also crucial for a sewer jet as various nozzles utilize the pressure differently and serve a different purpose. Other components of a sewer jetter include a given length of hose, 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.

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 you need to be cautious about some little things that I’m going to talk about as I carry on.

The first thing you need to do in this process is spending some money. Well, yes, it’s not free, but not as expensive as buying a jetter itself. Be ready to spend around 300 bucks that you’re going to buy a conversion kit with.

You’ll find many online stores, including Amazon, that sells the sewer jetter conversion kit. 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 that you want. You can also buy even cheaper variants if you wish to, but that will not include the hose reel with 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.

  1. Attach your ‘high-pressure’ water hose into the output of your pressure washer.
  2. Replace the spray gun of your pressure washer hose with the ball valve that comes with the conversion kit.
  3. Take the jumper hose, connect one end of it 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.
  4. Put your desired nozzle on the other end of the jetter hose.
  5. Make sure every connection is gentle and firm so that there aren’t any leaks.

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

Utilize your hose reel here to reach to the deepest part of the piping system. 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, take note that not all the conversion kits will be able to 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.

  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.
