The 110mm Underground uPVC Roddable Back Inlet Bottle Gully is an advanced surface water and wastewater management component designed to collect external runoff while providing easy access for cleaning and maintenance. Manufactured from high-impact, durable unplasticized polyvinyl chloride, this gully is engineered to withstand heavy outdoor weathering, ground pressure, and daily wear in residential or commercial settings. Its robust construction ensures long-term structural integrity and reliable performance beneath ground level.
 
Featuring a convenient back inlet connection, this gully allows secondary waste streams—such as discharge from kitchen sinks, washing machines, or rainwater downpipes—to feed directly into the trap alongside surface water. The integrated roddable access point is a key feature, providing a direct, straight-line path into the underground drainage run for rodding equipment. This allows maintenance personnel or homeowners to quickly clear blockages without needing to excavate or dismantle the surrounding pipework.
 
The internal design incorporates a removable dip tube that maintains an effective water seal, successfully blocking unpleasant foul gases from escaping near building foundations. The primary outlet integrates seamlessly with standard 110mm underground drainage pipes, ensuring a secure, watertight fit. Whether you are managing complex perimeter drainage or upgrading a domestic water system, this roddable back inlet bottle gully delivers professional-grade convenience, efficiency, and easy upkeep.
