150mm High Square Hopper Raising Piece

Product Description

Optimize your drainage inlet height and improve surface water capture with this 150mm High Square Hopper Raising Piece. Designed to fit over existing square hopper grates, this raising piece allows you to elevate inlets to match finished surface levels — perfect for installations where paving, decking, or slab finishes are raised. Whether you’re upgrading, remodelling, or installing new drainage, this component offers a reliable, clean solution to ensure your inlet sits flush and effective.

This raising piece features a square top opening (approx. 150mm dimension) with a lower socket sized for standard 110mm underground drainage pipework. Constructed from durable materials (such as PVC-U or equivalent plastic), it’s built to endure underground conditions: soil pressure, moisture, and typical environmental exposure. The component allows water to be collected more efficiently via the hopper top and directed into the drainage run, reducing surface water pooling and helping avoid overspill during heavy rainfall.

Because this is a raising piece, rather than a complete hopper, it integrates with your existing hopper and drainage assembly. It raises the height without needing to replace the full hopper or rework deeper pipe sections. Installation is straightforward: sit the raising piece over the existing hopper socket or flange, ensure proper bedding or solid support beneath, seal as required, and align with surrounding surfaces to ensure a flush finish.

Key Features

Benefits

• Match Finished Levels: Helps make your hopper inlet sit flush with paving or surfacing finishes, preventing trip hazards and improving aesthetics

• Improved Surface Water Capture: Raised inlet helps collect water more efficiently off surfaces, especially when finishes are built up (e.g. patios or new slabs)

• Cost-Effective Solution: Rather than replacing hopper units, this raise-piece adapts what you have — less waste, less labour, fewer components

• Easy Installation: Straightforward fit over existing units; less disruption than changing the full drainage part

• Durability & Performance: Material designed to last underground in damp, compacted conditions; retains strength under stress and resists wear
