Hot Tub Jet Identification

Please take 5 minutes to read all this information as it will make the process of correctly buying your spa jet simple.

Hot Tub manufacturers generally do not make their own jets, they are bought from specialist suppliers, the market share looks a bit like this.....

Waterway leads the marketplace, but Pentair and Rising Dragon are becoming more prevalent so it is important to identify them prior to making your purchase.

What is a Jet

Hot tub jets are designed to move a stream of water in different directions, the jet sits inside the jet body which is fixed into the hot tub, front faces are aesthetic and can sometimes identify your spa brand - examples being SUNDANCE® SPAS, Marquis & DIMENSION ONE SPAS®

How To Identify

Front Face

Firstly measure the front face diameter of the jet, and note the colour and style of the massage jet, most common are directional, rotational, twin rotational and massage....you can replace your existing jet with a different type of massage style if you want a change, as long as you ensure the front face diameter & diffuser are the same type....do not interchange jet manufacturers.

If you are doing a direct replacement, watch out with directional and rotational as they look identical except the rotational has a half-moon in the jet nozzle and the directional does not.

Diffuser

The rear of the jet is called the diffuser, you can replace just the diffusers, they cause the whole jet to pop out due to slightly poor water chemistry, even for the most fastidious of hot tub users this is inevitable after a certain period of time – it is due to a breakdown of the locking clips and the only way to solve the problem is to buy new jets or jet diffusers.

This will save you a lot of money but is very fiddly, each brand/ manufacturer has its own design which is specific to their jet bodies. They are not interchangeable with other brands.

Waterway diffusers have numbers that identify them, don't worry some jets don't have this code or it may have worn away or the plastic may have a build-up of scale, take a moment and scratch with your fingernail to see if you can reveal the code:

218-5140 Waterway Cluster Storm (Up to 2")
218-6930 Waterway Mini Storm (2"-4")
218-4000 Waterway Poly Storm(2"-4")
218-6610 Waterway Power Storm (5"+)

Threaded Waterway jets have the following identifying numbers

218-6530 – Mini and Poly Storm Jet Diffuser - the image shown
218-6550 – Cluster Storm Jet Diffuser
209-1021 - Power Storm Jet Diffuser

Rising dragon also has some numbers on their diffusers to help you identify your jets....

RD201-3011/12 Push-fit, typically 3-1/3" jets
RD203-3011/12 Threaded fit, typically 3-1/3" jets
RD203-5011/12 Threaded fit, typically 5" jets

Colour & Texture

Jets are supplied in grey - black - white and stainless steel or a multitude of combinations...to complicate matters you can have those colours in a textured finish (mottled) or a smooth finish.

Stainless Steel rimmed jets are available in grey, black or white internal plastic colours, in other words

The face has a Stainless Steel rim, whereas the actual jet nozzle/ internal is made of coloured plastic. Once again to make matters easier, grey stainless steel is by far the most common, followed by black stainless.

Sizes

If there are no identifiable markings, part numbers or logos on the jet face you can try to visually determine which brand you might have, here are the measurements for all our known jets

Waterway and CMP jets

Generally, there is confusion between Waterway and CMP jets, they have similar dimensions, looks and colours.

They are not compatible with each other, they are not interchangeable.

In short, Waterway and CMP have similar ranges:

Waterway Cluster Storm resembles the CMP Typhoon 200 series
Waterway Mini Storm resembles the CMP Typhoon 300 series
Waterway Poly Storm resembles the CMP Typhoon 400 series
Waterway Power Storm resembles the CMP Typhoon 500 series

Knowing the age of your spa helps in identifying if you bought your hot tub pre-2010, it typically will have Waterway jets, if your hot tub is post-2010, definitely check the references on your jet.

If you see a 218-4*** reference on the diffuser then it's a Waterway. If you can't see any reference, it may be a CMP nozzle.

Be aware that if no reference is visible (wear or friction), an opaque white rear jet diffuser will correspond to a Waterway jet, a transparent white rear jet diffuser will correspond to a CMP jet.
