Understanding Access Junctions, Pipes, Anti-Flood Gullies and Back Traps


Core Features in Business Installations


Drainage systems in industrial facilities require a set of specialised features to deal with liquids effectively. Components such as access junctions, access pipes, here anti-flood gullies and back traps support reliability and long-term function.



Linking the Network


Access junctions provide access for inspection while linking multiple pipes. Installed at sensible points, they make it easier to spot blockages and resolve them quickly. In complex drainage layouts, they streamline the effort needed for system upkeep.



Keeping the System Open for Checks


Access pipes are upright pipes giving direct access into the network. Placed at set intervals, they enable blockages to be cleared without disruption. They also serve as emergency outlets, reducing the risk of wastewater spilling inside commercial buildings.



Flood Defence


Anti-flood gullies block surface water from overloading drains. Ideal in areas of frequent rainfall, they block backflow and ensure water moving into the system. This lowers potential damage, helps stop business downtime, and shields property and staff.



Stopping Backflow


Back traps form a barrier that blocks wastewater moving in the wrong direction. Fitted at critical locations, they maintain hygiene, limit odours, and prevent unsanitary conditions.
