Component Developments were chosen by Sainsbury's to design a range of trapped gullies that would fit in with assemblies which were already in place and perform the necessary functions requested.
The gullies, a variation on our standard 5000 series gully, which as standard includes removable waste baskets, odour traps, rodding ports and 110mm diameter vertical outlet spigots, each included two back-inlets at 180 degrees to each other.
Grating for the gullies were either a smooth mesh or a sealed plate. For the smooth mesh grating there was also a tundish available. Tundish act like a funnel which directs the flow of water directly into the gully.
