Jet size calculators are widely available for down load on the internet. Nozzles with different efficiencies and flow rates need to be taken into consideration when calculating the orifice diameter of a Sewer Nozzle.
Hose Length and surface roughness is another important factor to take into consideration. Abtech Nozzles are calculated by our specially developed calculators each one is set up to suit a particular Nozzle. We retain the calculation results for each Drain Jetting Nozzle we dispatch, this way returning customers know we have the details of their pumps flow and Pressure. Sewer Cleaning or Drain Unblocking Nozzles can then be adjusted slightly from the last order, if there is any changes needed as a result of unforeseen ware on a customer’s pump or other related equipment. High Pressure Nozzles for Jetting of Drains require accurate calculations and precision drilled Jets to give the best performance from your machine. Nozzles Manufactured and sold by Abtech give customers the peace of mind that the nozzle they receive will work on the equipment its intended for. Jetter Nozzles are the most important part of a Drain Jetter this fact is often forgotten and the nearest jet size available is used this will cost money in terms of fuel, water usage and time.

Nozzle Jet angles will depend on the type of work you plan on doing. Jetting large pipes as a rule will need large nozzles. If you are trying to clean the wall of pipes you will need to use a Nozzle with a wide angle in order to scour the pipe wall, for example if the pipe needs patching. Nozzles with wide angles won’t have the same pulling power as narrower Jet angles but will leave the pipe cleaner. Drain jets for cleaning should also have more outlets this will ensure that the full circumference of the pipe gets cleaned.
Sewer Nozzles for long runs on the other hand you need a narrow angle to drive the jet head forward and drag the hose (Full of water) with it. High Efficiency nozzles are best for this type of work, such as cleaning storm drains from silt and sand residue. Nozzles of this type also tend to be big heavy heads this is due to more space needed inside the jet head to turn the water without losing to much energy. Heavy Nozzles also help by lying on the bottom of the pipe and drilling through the debris. Sewer jetter heads that stay on the Floor of the pipe also go through manholes easier as they don’t just fly up into the manhole.
Abtech Power nozzles come with two options one for cleaning and one for silt, and sand removal or long runs. Power nozzles for cleaning have a 35/30® split while nozzles for long runs have a 8/12®split.

Our bomb nozzles are precision machined in our factory on a nine axis mill turn center in one operation. This process insures that every nozzle we manufacture is within our tight tolerances, giving you the superior performance you need.
It’s what’s inside that counts the photo above shows the detail inside our nozzle to give the high power expected from a good nozzle. These nozzles are now available at a special introductory offer of €369.00 including carbide inserts while stocks last.

Safety
These nozzles/Jets are highly dangerous if not used correctly.
Improper use of these Nozzles can result in severe injury or death
Nozzles are only to be used inside a pipe or drain.
Never turn on your machine unless the nozzle is well inside the drain to be cleaned.
Our sewer/drain nozzles/Jets are not intended for DIY use.
Our nozzles are for professional use only by properly trained users.
Operators should fully know and understand the all the correct operating procedures for their jetting
machine before use.
We accept no responsibility for any misuse of these nozzles/jets.

Drain jetting as a matter of maintenance appears to have become a thing of the past. Jetting silt and sand from our drainage systems on a regular basis is bound to help reduce flood waters. Jetting our drains only seems to happen when there is a full blockage. Drains an sewers that are 1/3 full with sand silt and leaves can’t do their job. This is a result of budget cuts in the wrong places another false economy costing more in the long run.

Nozzle Selection
Nozzle selection requires you to look at the pressure and flow rate of your pump and the size of the pipes you intend to clear. Below is a chart giving guide lines to Nozzle size selection against the pipes that they are intended to work in (Fig 1.0) this is for our streamline jets for clearing blockages using this guide will help you get the most from your machine and labour. Nozzles used on small hoses like 3/8” or 1/2” give good accessibility in tight ubends and small pipes generally found in domestic work. Jetter hoses rom 3/4” up to 1” gives massive power for longer runs but due to the size and rigidity of the hose is not very effective at getting into ubends and corners found around most houses. Nozzles and hose diameter will also be restricted by the output of if your pump you have a high flow rate you will get sever pressure drop if the hose is too small if the hose is to big you lose accessibility and it will be too heavy to pull down the pipe not to mention the cost of buying the hose in the first place. Fig 2.0 gives a guide to hose selection vs hose diameter.

What nozzle do you use to break up a blockage? Most people use small low cost jets that can navigate tight bends but don’t offer very high efficiency . Some choose to use a bigger bomb type nozzle that give better efficiency. These nozzles are heavier and because of their extra power hit the blockage harder . This method drives into the blockage and gets the rear jets to the blockage faster. Currently we manufacture the smaller more agile nozzles that will get around corners better and put a lot of effort into getting the best efficiency from them. Soon we will be putting our range of bomb jets into production bringing more value and choice to our range. These nozzles will be manufactured on our 9 axis mill turn center giving excellent accuracy and consistency to our products.
