Selecting the ideal sewer jetter for your specific requirements is crucial for efficient and effective sewer and drain cleaning. Rioned offers a range of advanced high-performance jetters, including the CityJet, eCityJet, UrbanJet, and AquaJet. In this guide, we'll take you through the key considerations, particularly the water pressure and flow rate, to help you make an informed choice.

Understanding Jetter Pressure and Flow

Before we delve into the specifics of sewer jetters, let's briefly understand the significance of pressure and flow rate in sewer jetters.

Pressure: PSI or BAR represents the pressure at which water is delivered through the jetter's nozzle. A higher PSI/BAR means that the water is being forced through the nozzle with greater force. This high-pressure water stream is essential for breaking up and dislodging stubborn blockages, such as tree roots, grease buildup, or solid debris, within sewer pipes.

PSI (pounds per square inch) and BAR (barometric pressure) are two different units of measurement for pressure, and they are often used interchangeably in various applications, including jetting machines. However, there is a conversion factor between the two:

1 BAR is approximately equal to 14.5 PSI.

So, when it comes to water pressure in jetting machines, the primary difference between PSI and BAR is the unit of measurement used. PSI is commonly used in the United States, while BAR is more prevalent in many other parts of the world, especially in Europe, although the UK still primarily uses PSI.

For example, if a jetting machine is rated at 3,000 PSI, its equivalent pressure rating in BAR would be approximately 206 BAR (3000 PSI ÷ 14.5 PSI/BAR = 206 BAR).

Flow Rate: Indicates the volume of water delivered by the jetter per minute and is either expressed as GPM (Gallons Per Minute) or LPM (Litres Per Minute). A higher flow rate results in a greater volume of water flowing through the sewer pipe.

GPM is a unit of measurement commonly used in the United States and some other countries that still sometimes use the imperial measurement system, such as the UK. LPM is a unit of measurement typically used in countries that use the metric system, such as on mainland Europe.

To convert between GPM and LPM, you can use the following approximate conversion factor:

1 GPM = 3.78541 LPM

1 LPM = 0.264172 GPM

For example, if a jetting machine's water flow is rated at 16 gpm, its equivalent flow rate in LPM would be approximately 72 lpm.

In practice, the choice between pressure and flow depends on the specific cleaning needs and the type of blockage you're dealing with. For example, for routine maintenance and smaller pipes, a sewer jetter with moderate pressure and flow may suffice. However, for more challenging blockages or larger pipes, a sewer jetter with higher pressure and flow is often necessary to effectively clear the obstruction.
