What Nozzle Head Do I Need For My Jetting Machine?

Now you are ready to choose a nozzle there are many different sizes and combinations available on the market today. If your work consists of cleaning and scouring the walls of pipes you need a nozzle with a wide angle and as many jets of water as possible. This configuration will clean the whole wall of the pipe but the nozzle will lack traction for long runs. These types of jetter heads should be heavy to sit in the bottom of the pipe and have a high efficiency rating.

If you always seem to be removing sand and silt from pipes you need a nozzle with a combination of two angles something like 12 and 8 degrees this will give high pulling power and lift the silt from the floor of the pipe. These nozzles need to have a high efficiency up to 95% and also be heavy enough to sit in the bottom of the drain.

If your work is generally clearing blockages a small nozzle is probably best this type of head should be small enough to negotiate tight turns and ubends as these are generally the areas where blockages occurs.  Now you need to decide if you need a front jet and how many rear jets you need. If your machine is a low flow with high pressure i.e. below 40 litters per minute you should be looking at a four back with one or no front jet this keeps the size of the holes up so you won’t get dirt blocking the nozzle. The front jet can help impact the blockage but reduce the thrust of the nozzle. If no front jet is used and the blockage is soft it will drive in and gets the high power of the rear jets working faster. If the flow is above 40 litters per minute a six back jet with a forward will work better as it will give better cleaning than a four back and still have big enough jets to let small particles of dirt pas trough them.


When buying a new nozzle for your jetting machine don’t just buy the cheapest  nozzle you can find on the internet there are big differences in high quality computer designed & precision machined nozzles and the cheap imports that are just drilled to let water pass through.

Jetter Nozzle Of Science From Dublin Institute Of Technology

Flow Patterns

Figure 4-2, (DIT Nozzle 2, Shroud 1) and Figure 4-3, (DIT Nozzle 2, Shroud 2) show the shroud for DIT Nozzle 2. To further enhance the regularity of the flow direction a piping system in the top of the part is suggested. This is achieved by increasing the size of the protrusion in the top of the part so that it closes off against the cut-outs in the cap. This protrusion has a number of slots in order to serve as pipes that bring the fluid into the 5mm holes. At the base of the holes, a three dimensional cut-out has been introduced which in conjunction with the core brings the fluid to the exit of the nozzle in an effort to direct the flow in the desired direction.

Manufacturing of such a part could be difficult. However if the part is shown to optimise the product then it may be feasible to investigate the design of a similar product which is more convenient to manufacture.

Nozzle Efficiency
This is a very important factor to consider when choosing a nozzle for your jetting machine. A good efficient nozzle will save time money. In this economic climate we all need to get the maximum out of our investment. There are many cheap nozzles on the market today that for the occasional DIY user is fine. But if you are a professional trying to make a living from clearing drains you need to consider the hourly cost of a jetting machine vs the cost of a good nozzle after all it’s the nozzle that does the work. The longer you spend trying to get through a blockage the more water and fuel you are going to use not to mention getting less jobs done in a day. While water may not seem expensive you are going to have to stop jetting and fill up, when you should be on your way to the next job. We design our nozzles with this in mind. Even our small streamline jets offer efficiency up to 70%.

Drain Nozzle jet size For Your Machine

Nozzle Sizes
Did you know that nozzle sizes are not just for house hold power washers but there is no limit to nozzle size? Measuring the hole size of an existing nozzle that is working well on your machine to order a new jet may not be correct, as the orifice diameter will change according to the efficiency of the nozzle.But if you know the correct nozzle size it will always work correctly. To find the correct nozzle size you need to know the following information.
1) Internal diameter of your hose.
2) Length of your hose
3) Flow rate of your pump at maximum rev’s
4) The maximum operating pressure of your pump
An ideal jet size for your machine will operate at 90% of the maximum pressure at full RPM this will give good life on your pump and allow a little for any minor blockages in the nozzle.
