The Large General Purpose Headwall, weighing around 25kg, accommodates 200mm pipes with knockout options for 300mm and 360mm diameters, suitable for minor watercourses with moderate flow rates.

installation guide

expert tips and best practices.

Dig out sufficiently to allow the headwall flanges to finish flush with the batter. Take the outfall pipe (minimum length 1.5m of rigid impervious pipe) and slide it though the headwall so that it protrudes approximately 50mm. Make a good connection with the land drain and seal by returning approximately 150mm of soil into the trench and consolidating. Unravel the string and draw the anchor back along the trench as the rest of the backfilling is completed.
