The 110mm Underground Bottle Gully Rectangular Lid is generally used to connect waste pipes to the drainage/sewer system it can also be used for rainwater discharge.The advantage over a P trap is that the bottle gully has its own water seal to stop odours from coming out of the drainage/sewer system. When the grid and internal funnel are removed the bottle gully acts as an accessible rodding point. Waste and rainwater pipes can be connected by cutting the grid and pushing the pipes down below the level of the grid. The gully has a 110mm push-fit socket which can be connected to either spigots from bends or underground drainage pipes. The spigot on the hopper allows up to 32mm height adjustment.
