Everything You Need to Know About Waterway Diffusers
Around January 1 of 2018, Waterway stopped manufacturing many different varieties of snap in style jets.
So what do you do if your hot tub has these jets and they need replacing?
If your complete jet needs replacing, Waterway still makes a silver directional replacement jet in each size.
However if your jets are still in good condition and only the tabs on the back are broken, you may be able to simply replace the white piece on the back (called the diffuser).
To figure out which diffuser you need, see our comparison list below.
Waterway Diffusers and Descriptions
Waterway Cluster Storm
The Cluster Storm is a small diffuser and is typically used on jets with a face diameter of approximately 2 inches. They can also be used on face sizes of 2-1/4 inch and, very rarely, some 3 inch jets.
Waterway Mini Storm
The Mini Storm is slightly larger diffuser and is most often used for jets with a face size of 3 inch, 3-1/4 inch and 3-5/16 inch.
Waterway Poly Storm
The Poly Storm stepped diffusers are commonly used for jets with a face size of 3-3/8 inch, 3-3/5 inch, 4 inch, and 4-1/4 inch.
Waterway Power Storm
The Power Storm diffusers are usually used for jets with a 5 inch face diameter, however the whirlpool diffusers can also be used for this size of jet. The best way to determine this is to have a look at the back of your existing jet to see which one is required.
Waterway Whirlpool
Whirlpool diffusers also typically have jets with a 5 inch face diameter, however these jets move a lot more water then a power storm jet so they are often found in the footwell area. Usually there would be at most 1-2 whirlpool jets in a hot tub.
When replacing diffusers, keep in mind that Waterway brand diffusers will only fit Waterway brand jets.
Some other jet manufacturers make jets which look very similar but are not cross compatible.
If you need help determining which diffusers or brand of jets you require, send pictures of the back of your existing jet(s) to Pool and Hot Tub Depot by contacting us.
