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


Important Parts of Commercial Drainage Systems


Drainage systems in workplaces require a set of specialised features to here manage flow effectively. Components such as access junctions, access pipes, anti-flood gullies and back traps ensure reliability and long-term function.



Joining Pipework


Access junctions provide access for maintenance while linking multiple pipes. Installed at planned points, they make it easier to find blockages and remove them quickly. In extensive drainage layouts, they streamline the effort needed for system upkeep.



Providing Access for Maintenance


Access pipes are upright pipes giving inspection access into the network. Placed at set intervals, they allow blockages to be cleared without costly excavation. They also double as emergency outlets, reducing the risk of wastewater overflowing inside commercial buildings.



Protecting Premises from Water


Anti-flood gullies protect surface water from overloading drains. Effective in areas of frequent rainfall, they block backflow and keep water moving into the system. This minimises potential damage, avoids business downtime, and shields property and staff.



Stopping Backflow


Back traps provide a barrier that prevents wastewater moving in the wrong direction. Fitted at critical locations, they maintain hygiene, reduce odours, and avoid unsanitary conditions.
