Specifically designed to thread directly into the designated waste port of Sta-Rite® 1.5\" and 2\" side-mount six-position multiport valves—commonly paired with high-capacity System:2™ and System:3® series modular diatomaceous earth (D.E.) and sand filtration vessels—this specialized viewing window allows pool technicians and homeowners to observe the clarity of the discharged water stream. By providing real-time visibility during backwash and rinse modes, it indicates exactly when the internal filter media bed has been thoroughly cleared of debris, preventing unnecessary water loss and optimizing chemical retention. Precision injection-molded from a heavy-duty, impact-resistant clear polycarbonate polymer, the structural cylinder features robust male threads that form an airtight mechanical seal to eliminate external weeping or suction-side air induction under operating system line pressures up to 50 PSI. The premium plastic matrix provides permanent resistance to chemical degradation from high chlorine or bromine shock, advanced salt-chlorine generation, and intense pump room thermal cycling without clouding, cracking, or yellowing over time.
