There is much more to know about converting your pressure washer into a sewer jetter, and the difference between sewer jetters and pressure washers. Lets dive right in!

What’s The Difference?

Many people automatically assume that pressure washers and sewer jetters are the same thing because they both utilize pressure. That is simply not the case. There are many factors that separate them from each other.

The most identifiable difference between the two is the hose and nozzle. Sew jetter hoses are lightweight and can be pushed and inserted when inside a pipe. the Nozzles are also designed to pull the hose into the line which gives proper cleaning.

The flow of the two devices is also another significant difference between the two. The average pressure washer flows between 2.5 GPM and 4.0 GPM, while a sewer jetters flow starts at 4.0 GPM and build up the gallons per minute from there.

Another difference between the two is the sewer jetters have more features than a pressure washer that includes a pressure gauge to help with adjusting and jetting.

Drive Types

There are three different drive types that categorize pressure washers and sewer jetters.

  1. Direct Drive Units– This type of pump is attached to the engine and the pump runs at the same RPM as the engine. Direct drive units are often sold at hardware stores.
  2. Belt Drive Units– This unit provides a reduction of speed between the pump and the engine and it’s the standard of the commercial cleaning industry.
  3. Gearbox Drive Units– This unit has a higher oil capacity and has pumps that provide the same speed reduction as the belt drive units. It also offers more space efficient design choices.

How Do You Use a Sewer Jetter?

Before you use your sewer jetter, you will want to examine the body of the nozzle for any damage such as, cracks, obstructed holes, or worn threads. If there’s any visible damage on your sewer jetter, you should consider replacing it as soon as possible.

When you are ready to start cleaning, you must be sure that the nozzle is inserted into the line before turning the pressure on. Make sure that the nozzle is injected far enough into the line so that any backward facing jets wont risk harm to the worker using the sewer jetter.

Before removing the nozzle, you must always depressurize the system. Put a mark on the last 15 inches of the hose with either spray paint or tape. Make sure to do that in 5 sections so that you have an idea of how close the nozzle is to the entry as you get done with cleaning.
