Genuine Waterco 1.5 Inch Multiport Valve Rotor with Integrated 133mm Spider Gasket
The Genuine Waterco 1.5 Inch Multiport Valve Rotor with Integrated 133mm Spider Gasket is an official Waterco replacement part designed to restore smooth, accurate, and leak-free operation to your Waterco multiport valve. Manufactured to precise factory specifications, this rotor and gasket assembly ensures the correct separation of water pathways inside the valve, maintaining optimal filtration efficiency and preventing unwanted water bypass.
This genuine component is engineered specifically for Waterco 1.5 inch multiport valves, offering a perfect fit, long-term durability, and reliable performance under continuous pressure. With the 133mm integrated spider gasket moulded directly into the rotor plate, this kit eliminates common sealing issues caused by worn, deformed, or poorly seated gaskets. The rotor itself has an overall diameter of 143mm, ensuring accurate alignment and smooth rotation through all valve positions, including filter, backwash, rinse, waste, recirculate, and closed.
A worn or damaged rotor assembly can cause internal leaks, water escaping down the waste line, reduced flow rates, and imbalanced filtration cycles. Replacing the rotor with this genuine Waterco part helps restore correct functionality, protects the pump from low-water conditions, and supports the overall longevity of your filtration system.
