Designed as an OEM-style replacement internal for Waterway Plastics Mini Storm series spa and hot tub jet body assemblies.
Installation should be performed by a qualified pool and spa service technician. Before servicing jet internals, shut off all pump and blower circuits at the breaker and allow system pressure to fully depressurize. Jet internals typically snap or thread into the jet body housing and require no special tools, but the jet body face and lock ring should be inspected for wear at the same time. Follow all applicable local codes and manufacturer guidelines for spa equipment service.
