Waterway offers a variety of spa jets with an assortment of eyeball types, fittings, and internals. Ranging from massage jets for reaching a broader region of the body to directional storm jets for a more focused feel, there are many options to choose from.
Most spas use a combination of styles to target different areas simultaneously for a unique and relaxing spa experience. Because a spa usually includes a mixture of jet types, it will require a little work and research when it comes time to replace them.
Generally, Waterway jets have two connection types: snap-in and thread-in. In this article, we’ll go over the differences and show you what to look for when replacing your spa jets.

Which Waterway Jet Do I Need?
Whether you’re looking to replace worn or damaged jets or just upgrade your existing ones, it’s important to know what type of connection your existing jets have. In order to determine this, pull out one of your jets and take a look at the diffuser. The diffuser is the part of the internal that inserts into the jet assembly or fitting. See diagram below.
Please note: diffusers can be sold separately for snap-in and old style thread-in but are included with internals.
It’s common for older spas to have a poly jet or a snap-in style internal. If you’re upgrading your jets with a different style, keep in mind that you will also have to replace your jet body housing to accommodate the change.
