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

Essential Features for Business Drainage

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

Connecting the Drainage Network

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

Making Maintenance Straightforward

Access pipes are vertical installations that enable direct entry into the system. Installed at set points, they allow professionals to clear obstructions and carry out routine checks. They can also serve as safety valves, reducing the chance of wastewater causing issues indoors.

Flood Protection

Anti-flood gullies block surface water overwhelming drains. Effective in areas with frequent heavy rain, they ensure water flowing in the right direction, minimising the risk of overflow. For businesses, this helps protect property.

Maintaining Proper Flow

Back traps function as barriers to stop wastewater reversing back into the network. Placed in important positions, they maintain hygiene, control odours, and prevent contamination inside commercial areas.
