Revitalize your spa’s hydrotherapy with the Waterway Power Storm 5" Massage 5-Point Scallop jet. This directional, snap-in jet from Waterway Plastics delivers focused, columnist-grade massage that soothes sore muscles and enhances relaxation after a long day. Although the original 212-7747 model is obsolete, the trusted 212-7639-STS replacement is designed to drop right into your existing Power Storm lineup, preserving performance and compatibility for years to come.
What makes this jet stand out
-
5" face with a textured five-point scallop provides a broad, ergonomic massage surface and a secure grip when you adjust the jet’s direction. This design is ideal for targeting shoulders and upper back while maintaining a comfortable, even flow.
-
Directional, snap-in internal jet means you can fine‑tune the spray pattern and orientation without tools. It’s engineered for straightforward retrofits into Waterway’s Power Storm systems, keeping installation simple and reliable.
-
5" diameter face and 5-3/8" overall length align with standard spa configurations, ensuring a seamless fit when upgrading or repairing existing jets. The face style—sterling silver/gray with finger-like scallops—blends discreetly with most spa interiors.
-
Quality you can trust from Waterway Plastics—a brand known for durable spa parts designed to endure frequent exposure to water, chemicals, and heat. These jets are manufactured to fit Waterway’s Power Storm family and are supported by a robust retrofit ecosystem.
Ideal use cases and benefits
- Retrofit older spas that used the Power Storm line, restoring original massage intensity without a full remodel. The 212-7639-STS replacement specializes in the same 5" scalloped profile for a familiar feel.
- Upgrade your hot tub’s hydrotherapy by adding precise, directional flow to pinpoint tight areas along the back and shoulders, while maintaining a broad spa-wide circulation for overall comfort.
