Hayward STARTUP ASSY

The Hayward Startup Assembly is designed to support the initial filling and balancing phase of a new pool by providing a controlled way to introduce water and manage early circulation needs before the full equipment set is activated. It typically includes components that help regulate flow, protect the system from debris during construction cleanup, and ensure water enters the pool smoothly without disturbing fresh surfaces such as new plaster. The assembly is built from durable, chemical‑resistant materials so it can withstand the demanding conditions present during startup, and it allows installers to maintain proper water levels and flow paths while the pool is being brought online for the first time. Based on similar Hayward startup‑phase components, the estimated weight generally falls in the 1–3 lb range.
