Nozzles 101 – Choosing Spray Patterns for your Application
Every jetter has a fixed amount of power. The choice of a spray pattern determines how the jetter’s power will be used.
Spray Angles Matter!
- Angles aimed towards the pipe sidewall deliver more cleaning power.
- Angles directed more parallel to the hose deliver more pulling power.
- More of one = less of the other Factors to consider when choosing a spray pattern to match an application
How long is the run?
- LONG RUNS REQUIRE MAXIMUM PULLING POWER. CHOOSE PATTERNS WITH PULLING POWER (15° – 30° rear jets).
- SHORTER RUNS REQUIRE LESS PULLING POWER.
- Choose patterns with more cleaning power (35° – 55°) to work more effectively.
Is the pipe blocked?
- If blocked, a forward jet or jets are required.
- If not blocked, a forward jet is optional.
FORWARD JETS WILL REDUCE OVERALL DISTANCE CAPABILITIES.
If distance is a consideration choose a blind nozzle (no forward jet).
Are you pushing or pulling?
- Pushing debris forward is more efficient with a pattern using multiple forward jets (Degreaser pattern).
- Pulling heavy debris like sand or gravel is aided by the use of dual rear angles (Monster pattern).
HotJet USA tests nozzles in their own facility and field test with thousands of plumbing, rooter and municipalities that operate their jetting equipment and from whom they receive tons of application feedback. HotJet USA’s custom drilled sewer nozzles have set the “Industry Standard” in Quality and Performance. They partner with the largest nozzle manufacturers in the industry and share in the development of their nozzle packages including the WT 3/8” Warthog nozzle with Stone Age Manufacturing – worldwide leader in Nozzle Tool Design and Engineering – and the custom kits from Arthur Products.
