Unblocking or cleaning. Large or small pipe. Large water volumes or small water volumes. High pressure or low pressure. Whatever you want to do, there is a right spray nozzle for everything. With emphasis on right.
That’s because clearing a blockage with the perfect high-pressure sewer cleaning machine or sewer combi without the right spray nozzle is like letting Messi play football wearing a pair of clogs. You are 1-0 behind before you've even started.
By cleaning better and faster you also benefit from; less fuel and water consumption, lower labor costs, less wear and tear on your equipment and less inconvenience to the environment.

We’re talking about spray nozzles here. Yes, you read that correctly. Plural. Because 1 spray nozzle is simply not enough unless you are going to do exactly the same job every day.
You are likely to encounter many different problem scenarios with the various customers you encounter. One may have a grease blockage, the other a pipe with roots growing through it, and another a pipe full of wet wipes. And then one may have a small pipe and the other a larger one.
To further explain why you should use the correct spray nozzle for each situation, we will zoom in on the technical side of the story. Your sewer cleaning machine or sewer combi is designed to deliver a maximum pressure (in bar) and a maximum number of litres of water per minute.
To get the most out of your machine, it is important to choose a spray nozzle that, although made for a specific blockage, also matches the pressure and the number of litres per minute of your machine.
If you want to solve a problem as quickly as possible and achieve the best result, you need a spray nozzle to rapidly resolve the problem professionally. This will save you time.
You will be finished faster compared to using any old spray nozzle you find lying around. Customer happy, you happy. Because then you will have some extra time to do an extra job, and earn some extra money. In other words, you will earn your investment back many times over.
By cleaning better and faster, you also benefit from:
Less labor costs
Less fuel consumption
Less water consumption
Less wear and tear on your equipment
Less inconvenience to the environment
Without the spray nozzle, your sewer cleaning machine or sewer combi will not reach pressure. In very technical terms, no pressure without counter pressure. That counter pressure can only be created by the spray nozzle that is attached. A spray nozzle has holes, also called inserts. The water spurts through these holes.
If you choose the wrong spray nozzle with holes that are too small, your sewer cleaning machine or sewer combi will not reach the number of litres of water per minute. However, the small holes will build up a lot of pressure in the machine. This may cause damage to the machine. This is not what you want, right?
If you choose the wrong spray nozzle with holes that are too large, your machine will achieve the right number of litres of water per minute, but not the required pressure. This is why it is always important to get good advice when purchasing.
We not only look at the spray nozzles that best fit your machine, but also those that best fit your hose diameter, hose type and hose length. You will also lose pressure if the water has to go through an 80-metre hose first. And a rolled up high-pressure hose can also have a negative effect on the pressure delivered by the spray nozzle, did you know that?
You can pressurise your sewer cleaning machine or sewer combi yourself via the pressure regulator. The number of litres per minute can be set via the engine throttle. More throttle will deliver more litres per minute and less will reduce the litres delivered.
Do you want to clean and remove dirt? Then set a low pressure with a high number of litres per minute. This will give the best result for flushing the debris from the drain pipe. Is there hard material, such as grease, cement or scale, stuck in the drain pipe? Then turn up the pressure to force the material to loosen.
If you want to solve a problem as quickly as possible and achieve the best result, you need a spray nozzle to rapidly resolve the problem professionally. But which spray nozzle do you need and when? An explanation is provided for each problem below.
To break a complete blockage in a pipe, use a standard spray nozzle with maximum thrust to properly penetrate a blockage. The standard spray nozzle to use for this are blow nozzles.
These often have a powerful forward water jet that can easily break through a complete blockage. The most important function of blow nozzles is to get as far as possible into the pipe and thus break through and remove the blockage.

To rinse waste and debris away in a pipe, you need a standard spray nozzle with a water jet that passes low over the pipe wall so the debris can rinse away properly. Some spray nozzles have water jets that face in various directions. All of this is designed to rinse waste and dirt away as quickly as possible.

Available in a variety of formats. From 1/4” tot 1 1/4”.
The best method to remove adhesions, such as limescale, from the wall of a pipe, is to use a rotary spray nozzle. The spray nozzle uses powerful water jets on the inside of the pipe to loosen the limescale.
A rotary spray nozzle is also recommended if there are many bends in the pipe. Other spray nozzles often leave dirt along the inside of the pipe. A rotary spray nozzle is made for loosening and rinsing limescale from the pipe.

There are many different spray nozzles available for grease cleaning. For the best result, choose a rotary spray nozzle. These spray nozzles have water jets at an angle of both 30° and 75°, and at an angle of 10° and 20° for cleaning. Ideal for optimal rinsing and cleaning.

For light root growth, use a rotary spray nozzle. It is important that the spray nozzle is a slow rotating type. Cheaper rotary spray nozzles cannot control the rotation speed, which means the water jet cannot act on the roots in a controlled manner. You can also use a chain scraper/sewer cutter for these kinds of problems. Tip: use a sewer camera to check all the roots have been removed.

Standard spray nozzles in the shape of an egg or a grenade create a suction effect in the drain pipe due to their shape. Wet wipes, cans and stones are sucked over the spray nozzle and then rinsed away.
