Waterway Poly Jet Internal Pulsator

This internal is designed for Waterway Poly Jet housings. Before purchasing, verify that your existing jet face and housing are part of the Waterway Poly Jet series, as these internals are not universal across all spa brands.

No, this is a drop-in replacement. You simply remove the old internal by twisting it counter-clockwise until it unlocks from the housing, then snap the new one into place.

A directional jet provides a steady, focused stream of water, whereas a pulsator jet features an internal mechanism that creates a rhythmic, pulsing sensation. This creates a more varied massage experience that mimics kneading.

You only need to replace the internal component if your existing housing is intact and free of cracks. Replacing just the internal is a quick, cost-effective way to restore massage performance without draining your spa or cutting into plumbing.

Generally, no. Spa jet internals are proprietary to their specific housing designs. Unless your spa specifically uses Waterway Poly Jet housings, this internal will likely not fit or lock into place correctly.
