Keep your underground drainage operating at peak efficiency with the Brett Martin Single Socket Level Invert Reducer (B7131).Manufactured in the UK, this specialist fitting is designed to adapt a 160mm main run down to a 110mm pipe line without causing a step or lip along the bottom of the system.

Why Choose a Level Invert Reducer?

Unlike standard concentric reducers, a level invert design keeps the floor (invert) of both connected pipes completely level with one another. This critical feature:

• Eliminates Flow Obstructions: Prevents solids and waste from snagging at the transition point.

• Maintains Consistent Gradients: Essential for gravity-fed foul and stormwater systems to prevent standing water or blockages.

• Saves Trench Depth: Eliminates the need for extra ground excavation just to align different pipe diameters.
