Starway - Automatic Backwash Valve Lower Cap ABS 50 mm - 7039418

Starway – Automatic Backwash Valve Lower Cap ABS 50 mm

This is the genuine OEM lower ABS cap for the Starway motorised 5-way automatic backwash valve in the 50 mm pipe diameter version. It forms the lower closing section of the valve body, maintaining a watertight seal and protecting the internal valve components during filtration and backwash cycles. Keeping this cap in good condition is essential for reliable, leak-free operation of your pool’s automated filtration system.

Compatibility

This lower cap is designed exclusively for the Starway motorised 5-way automatic backwash valve with 50 mm pipe connections. It is not interchangeable with the 63 mm Starway valve variant. Always verify your valve’s pipe diameter before ordering to ensure a correct fit.

Why Genuine Matters

As a genuine Starway spare part, this cap is manufactured to the exact tolerances of the original valve assembly. Aftermarket alternatives risk poor sealing, premature wear, or incompatibility with the valve’s internal components — any of which can compromise automated backwash performance and lead to costly downtime.

Installation

Replacement of internal valve components, including the lower cap, should be carried out by a qualified pool technician. Always isolate the system electrically and hydraulically before beginning any service work on the Starway valve.
