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

Main Elements of Drainage in Commercial Premises

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 support in keeping the system operational and robust over time.

Joining Multiple Lines

Access junctions join several pipes and provide entry points for checks. Located at appropriate positions, they make easier fault finding and removing blockages. Without them, upkeep in extensive networks would be labour-intensive.

Making Maintenance Straightforward

Access pipes are vertical sections that permit 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. Effective in areas with frequent heavy rain, they keep water flowing in the right direction, reducing the risk of flooding. For businesses, this helps limit downtime.

Keeping Wastewater Moving Correctly

Back traps act as barriers to prevent wastewater reversing back into the network. Placed in important positions, they help hygiene, limit odours, and avoid contamination inside commercial areas.
