Waterway Jet Diffusers

Are your jets falling out the wall of your tub?
Is there a chalky white residue floating on the water?

If your jet nozzles are still in good condition the diffusers may need replacing not the whole jet!
Waterway - Custer Storm Jets, Mini Storm Jets, Poly Storm Jets, Power Storm Jets all use diffusers.
These diffusers are part of the jet assembly, the white part or the stem on the rear of the jet.
The diffuser part number is usually visible on the part & some mistake that number for the part # of the whole jet.

There are four sizes of diffuser, one for each jet in the Waterway Storm series.
218-5140 for Cluster Storm, jets with 2" Face
218-6930 for Mini Storm, jets with 3" Face
218-4000 for Poly Storm, jets with 3-3/8" - 4" Face
218-6610 for Power Storm, jets with 5" Face


Most spa owners will change out jet diffusers at least once in their spa's life, others will change them every few years. Water quality and chemical content vary by city, some areas will be harsh on these plastic components.

Spa Jets?

One of the most common questions we are asked is "How do I know what jets I have/need?"

There are a few ways to answer this.
  1. Browse our jet categories by clicking here
  2. Start with Waterway or Pentair as they are the two most common jet manufactures.
  3. Nozzle style is irrelevant as are any trim ring patterns. Some spa makers have exclusive branding or patterns in the trim ring this does not affect the function of the jet. Also note the difference/comparisons in the diffuser styling (stem on the rear of the jet).
  4. Measure the face(Trim Ring or Escutcheon) diameter of the jet you are trying to replace. Most jets are categorized by face diameter.
  5. Determine which series your jet belongs to using the above steps.
  6. Each jet series (Poly Storm, Cyclone Euro etc...) is comprised of jets the same size with different nozzles and trim ring designs. Trim rings are only aesthetic, most customers opt for the cheapest replacement.
  7. Sending us a picture via email with measurements always easier.

Most spa manufactures do not make their own parts. Generally spa makers will choose either Waterway or Pentair to supply jets for their tubs although there are exceptions and other smaller brands.
