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

Important Components in Commercial Drainage


Commercial drainage systems are made up of multiple components, each with a specific function. Access junctions, access pipes, anti-flood gullies and back traps all assist in keeping the system functional and reliable over time.



Connecting the Drainage Network


Access junctions connect several pipes and offer entry points for checks. Located at planned positions, they simplify fault finding and resolving blockages. Without them, upkeep in complex networks would be difficult.



Keeping Access Simple


Access pipes are vertical sections that allow direct entry into the system. Installed at regular points, they make it easier to deal with obstructions and carry out routine checks. They can also double up as safety valves, reducing the chance of wastewater causing issues indoors.



Defending Against Flooding


Anti-flood gullies stop surface water overwhelming drains. Useful in areas with frequent heavy rain, they ensure water flowing in the right direction, avoiding the risk of flooding. For businesses, this helps keep operations safe.



Maintaining Proper Flow


Back traps work as barriers to stop wastewater reversing back into the network. Placed in key positions, they support hygiene, reduce odours, and prevent contamination inside commercial areas.
