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


Core Features in Business Installations


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



Joining Pipework


Access junctions allow access for cleaning while linking multiple pipes. Installed at planned points, they help to spot 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 make blockages to be cleared without major works. They also serve as overflow points, reducing the risk of wastewater spilling inside commercial buildings.



Reducing Flood Risk


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 reduces potential damage, prevents business downtime, and protects property and staff.



Maintaining One-Way Flow


Back traps create a barrier that stops wastewater moving in the wrong direction. Fitted at necessary locations, they help with hygiene, control odours, and prevent unsanitary conditions.
