Joining Pipework


Access junctions provide access for maintenance while linking multiple pipes. Installed at planned points, they make it easier to find blockages and deal with them quickly. In complex drainage layouts, they reduce the effort needed for system upkeep.

Preventing Wastewater Return


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