Stormwater LIT

Stormwater LIT – Level Invert Taper Downpipe Adaptors

The Stormwater LIT (Level Invert Taper) range provides a reliable solution for adapting downpipes into stormwater drainage systems. These fittings are designed to connect different pipe sizes while maintaining a smooth internal flow, ensuring efficient water movement from downpipes into the stormwater line.

By accommodating transitions between varying diameters, LIT adaptors are essential for both domestic and commercial drainage installations. Made from high-quality PVC-U, they offer strength, chemical resistance, and long-lasting performance in underground and above-ground applications.

Key Features

• Downpipe to Stormwater Connection – Ensures smooth transition between different sizes.
• Level Invert Taper (LIT) Design – Minimises flow disruption and pressure loss.
• Durable PVC-U Construction – Tough, corrosion-resistant, and UV stable for outdoor use.
• Versatile Application – Suitable for domestic housing, commercial sites, and infrastructure projects.
