Fluidra - Sand Drain Kit 1½" for Cantabric Sand Filter

Fluidra – Sand Drain Kit 1½” for Cantabric Sand Filter

This is the genuine Fluidra replacement sand drain kit for the AstralPool Cantabric series sand filter, fitted with a 1½” connection. Located at the base of the filter tank, it serves a dual purpose: draining water from the filter and providing an outlet port for emptying or replacing the filter sand. The kit includes all necessary nuts and gaskets for a complete, leak-free installation.

Compatibility

This drain kit is designed for AstralPool Cantabric sand filters, including models with a side-mounted or top-mounted multiport valve up to Ø600 mm tank diameter. The parent assembly is the Cantabric Ø750 mm / 21,000 l/h filter with a 2″ top valve. Always cross-reference your filter’s model number before ordering to confirm fitment.

Why genuine matters

As a factory-original Fluidra spare part, this drain kit is manufactured to the exact tolerances of your Cantabric filter. Genuine components ensure a reliable seal under operating pressure, reducing the risk of leaks at the tank base. Aftermarket alternatives may not match the thread profile or gasket dimensions, leading to premature failure.

Installation

Turn off the pump and fully depressurise the filter system before beginning work. The kit arrives with its sealing gaskets and retaining nuts pre-assembled for straightforward fitting at the bottom of the filter tank. No special tools are required, though a wrench is recommended to achieve a firm, watertight torque on the 1½” fitting.
