You will find dozens of different jetting nozzles by as many different nozzle suppliers but how to choose the right one for the job?

Some guidelines…

Divide by dimensions/weight of the nozzle

Small nozzles are used in smaller diameter tubes. In combination with small (flexible) hoses so they will pass bends better in pipes of a small diameter.

Large nozzles are used in large diameter tubes.

There is no guide rule that determines how large a nozzle should be but there are a number of factors to consider.

Tube size determines which hose/nozzle is suitable

Larger tubes need more water to be flushed and for that you need a larger pump, which has a larger hose (diameter) so more water can pass through and not too much pressure loss is built up in the hose itself and so a larger nozzle fits that.

A (too) small hose in a large tube can turn over in the tube causing the nozzle with hose to come back to the entrance instead of pulling itself deeper into the tube. This can even lead to dangerous situations.

A small nozzle (and hose) is much lighter in weight which, when used in larger diameter tubes, causes it to float in the tube losing its effect, as most debris is always at the bottom of the tube.

It is also important that the distance of the water jet from the dirt is as short as possible.

The water jet loses power as it gets longer and thus a hard deposit cannot be removed properly, if at all, if there is not enough power.

Divide by type of nozzle

Static nozzles have no moving parts, the non-moving water jets spray the dirt away. Therefore, the disadvantage is often that some parts of the pipe are not reached, leaving residue. Some manufacturers offer nozzles with additional water jets or flat jets but these are less powerful and thus will not be suitable for removing very hard deposits.

Dynamic nozzles have moving water jets that allow them to cover a larger area and therefore clean better. The moving water jets ” seek out” the weaker spots so they are more likely to crumble, thus starting to remove the clog. The rotating water jets will also ensure that no residue is left anywhere.

Dynamic nozzles can be further subdivided into hydrostatic (which clean with water only – the water jet does the work) and mechanical nozzles where additional tools such as chains, saw blades or other attachments are driven using the water jets. These attachments are extremely effective against extra hard and or extra difficult to remove blockages. For example, chains are used to smash stones, saw blades or cutting chains for cutting through roots and drill heads for drilling holes etc. etc.

Another kind of division: by solutions (effectiveness).

The 80/20 rule is commonly used in sales where it is stated that 80% of sales are realized by only 20% of the products one offers.

In sewer cleaning, the 80/20 rule means:

80% of problems can be solved with only 20% of available nozzles.

So with only a limited number of nozzles, most standard problems can be solved. Additional (special) nozzles can be purchased for special problems.

How to compile a set

It is often useful to put together a slightly more comprehensive range so that the effectiveness of nozzles is maximized. Just a few types of nozzles can probably solve as many as 80% of problems but without effectiveness, the job is no longer profitable.

Some explanation about the effectiveness:

Wrong nozzle for existing pump capacity => loss of efficiency => loss of money

Too low pressure: you have under capacity and therefore not enough power so you can’t clear the blockage well enough and you’ll be working longer (loss of time, water and fuel) or you’ll leave residue and thus you’ll have to go back in a short time to redo the job.

Too high pressure: you basically have excess capacity, the by-pass in the machine will do its job but you are using more fuel than you would really need (wasted) or you now have too little water so you have no ” striking power” to wash away the dirt.

Nozzle is not suitable for diameter of pipe => loss of efficiency => loss of money

Nozzle is too small: you don’t have enough flow, the dirt can’t wash away or the distance of the water jets from the pipe wall (where the clog is stuck) is too far and thus you don’t have enough power.

Nozzle is too large: because of this, too much water gets into the small pipe, overpressure in the pipe, this can lead to serious damage in houses… Also, sometimes an oversized nozzle just can’t get through the bends or constrictions in the small pipes so you can’t reach the blockage.

NOZZLES 123 offers a range of different nozzles to unblock and clean almost every pipe.

Standard nozzles (with front jet / without front jet) come standard with your machine. These basic nozzles can provide excellent solutions for many standard problems.

Singlejet nozzle has only 1 front jet and is used to cleaning out manholes/pumps or the workplace.

Pointed (chisel) nozzle is ideally suitable for piercing (puncturing) the blockage. 4 Front jets are cutting into the soft materials while the sharp chisel edges will ram with is kinetic energy into the blockages.

Grenade nozzle cleans the circumference of a pipe and removes heavy debris like stones and sand while pulling back out. Designed for larger pipe diameter or pipes of longer lengths.

Rotating nozzle has multiple jets in different angles towards the pipe wall. The rotating jets clean the entire pipe wall ensuring a streak free cleaning result.

Aquadrill nozzle has a rotating front jet. This nozzle is extremely effective for piercing blockages and can even cut through tree roots inside the pipes.

Sandshoe nozzle / Flounder nozzle extremely effectively cleans large deposits of sand, mud, pebbles, gravel and other stones or solids from the bottom of the pipe, submerged or not. Even in pipes with a strong current, this nozzle will stay on the bottom of the pipe due to its heavy weight and special shape allowing the 4 powerful water jets to do their work.

Vibro Rotating nozzle owes its performance to an eccentrically supported rotor that generates ultra-fast and strong vibrations. Mineral deposits, concrete, mortar and grout of up to 10cm thickness are disintegrated and detached from the pipe wall.

Turbo Cyclone® chain rotating nozzle passes effortlessly through 90-degree bends in pipes from 100mm to remove roots, minerals and other hard blockages. Also ideal for roughening pipes prior to pipe repair (pipe rehab).

The chains which are mounted around the rotor support the nozzle while rotating to self centre itself and as more chains on the outer side will hit the pipe wall it will remove crusts,

The TC is the first chain rotating nozzle that allows you to mount chains around the rotary to become a CYCLONE chain nozzle. It will centre itself perfectly and the CYCLONE chains have more chain links on the outside diameter making it the perfect tool for descaling pipes.
