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

Core Features in Business Installations

Drainage systems in workplaces require a set of specialised features to handle water and waste website effectively. Components such as access junctions, access pipes, anti-flood gullies and back traps help maintain reliability and long-term function.

Joining Pipework

Access junctions provide access for maintenance while linking multiple pipes. Installed at sensible points, they assist to spot blockages and resolve them quickly. In extensive drainage layouts, they reduce 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 regular intervals, they enable blockages to be cleared without costly excavation. They also serve as emergency outlets, reducing the risk of wastewater escaping inside commercial buildings.

Flood Defence

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

Preventing Wastewater Return

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.
