Guide to Access Junctions, Pipes, Anti-Flood Gullies and Back Traps


Main Elements for Business Drainage


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



Connecting Drainage Lines


Access junctions allow access for inspection while linking multiple pipes. Installed at convenient points, they help to detect blockages and resolve them quickly. In large-scale drainage layouts, they simplify 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 planned intervals, they enable blockages to be cleared without disruption. They also act as backup safeguards, reducing the risk of wastewater escaping inside commercial buildings.



Reducing Flood Risk


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



Preventing Wastewater Return


Back traps create a barrier that blocks wastewater moving in the wrong direction. Fitted at necessary locations, they support hygiene, reduce odours, and avoid unsanitary conditions.
