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


Core Features in Business Installations


Drainage systems in business properties require a set of specialised features to handle water and waste effectively. Components such website 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 planned points, they make it easier to detect blockages and deal with them quickly. In large-scale drainage layouts, they simplify the effort needed for system upkeep.



Making Inspection Easier


Access pipes are upright pipes giving inspection access into the network. Placed at planned intervals, they make blockages to be cleared without disruption. They also double as overflow points, reducing the risk of wastewater overflowing inside commercial buildings.



Protecting Premises from Water


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



Maintaining One-Way Flow


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