Hayward - MasterFlo Hydrostatic Collector Drain with Valve

MasterFlo Hydrostatic Collector Drain with Valve

The MasterFlo Hydrostatic Collector Drain with Valve is a high-flow pool drain from Hayward’s MASTERFLO range, built to comply with European anti-entrapment safety standard EN 16571. It provides efficient water return circulation from the pool floor while the anti-vortex design prevents dangerous suction entrapment — a critical safety requirement for all modern pool installations.

Available in multiple colour finishes to match the pool interior, the MASTERFLO drain integrates cleanly into tiled or liner finishes.

Key Features

• Anti-entrapment design — compliant with EN 16571 European safety standard
• High-flow capacity for efficient pool floor circulation
• Available in multiple colour finishes to complement any pool interior
• Durable ABS construction with UV resistance
• 2″ (50mm) pipe connections — compatible with standard pool plumbing
• Anti-whirl cap prevents vacuum entrapment

Installation

The drain is installed in the pool floor or wall during construction or renovation. Always install a minimum of two drains per pool, spaced at least 1 metre apart, to comply with anti-entrapment regulations — this ensures that if one drain is blocked, the other prevents dangerous suction build-up. Connect to the suction line with a properly rated sump box.
