160mm Underground Drainage

160mm underground drainage is the larger-diameter below-ground system for jobs where 110mm does not carry enough flow: commercial developments, larger domestic properties, and surface water and foul drainage runs that take higher volumes. It ties into the rest of a drainage layout through reducers down to 110mm and adaptors to clay and other pipe types. At Speedy Plastics we stock the full 160mm range: pipes in standard lengths, bends and junctions for changing direction and branching, couplers, reducers, adaptors, and access fittings for rodding and inspection. Products come from trusted drainage manufacturers for strength, durability and straightforward ring-seal installation. 160mm is typically specified as the main carrier drain on a site, with 110mm branches running off it into individual connections. Where a run needs access for inspection or rodding, pair it with a 160mm inspection chamber.
