Waterway is an American manufacturer who supplies its jets and other components to around 80% of manufacturers of Hot Tubs around the world today. Chances are your spa has a Waterway component.
There are many different variants to their jets, this overview covers there most popular types used in the UK past and present.
Waterway Jet Bodies
This is the part that fits through the spa shell and connects to the spas plumbing, the jet front fits into the jet body. In most cases the jet has two pipe connections a larger one for water and a smaller one for the air. Different connection types/sizes are also available in each jet body range so please look at the jet bodies available in each range before buying.
Waterway Jet Fronts (internals)
This part provides the finished look of the jet, and allows the user to control the flow, get the desired massage from the different flow patterns (Jet Fronts) available - Jets fronts are interchangeable within their jet series. Older waterway storm jets use a Push Twist and Click system and their newer ones use a screw version.
Note
Some of the smaller and older Jets produced combine the two into one, meaning the jet body and jet front are all one, normally these jets are a simple fixed flow jet, the jet front is both the finished surface (escutcheon) and the jet body wall fitting. An example of this kind of jet would be the waterway Cluster or Ozone Jet - see image
