Why this diffuser back matters
In a spa system, the diffuser back is the critical stage that wraps the jet’s flow in a controlled channel. By evenly distributing water behind the Power Storm Jet insert, it helps reduce turbulence, minimizes vibrations, and produces a smooth, powerful spray. This translates to a more consistent massage experience and less wear on surrounding components over time.
