The 110mm Underground uPVC Rear Inlet Bottle Gully is an essential surface water management component designed to collect and redirect rainwater while preventing foul odors from escaping the drainage network. Manufactured from durable, high-impact unplasticized polyvinyl chloride, this gully is engineered to withstand heavy outdoor weathering, ground pressure, and the rigors of residential or commercial environments. Its robust construction ensures long-term structural reliability and dependable performance at ground level.
 
Featuring a convenient rear inlet connection, this gully allows secondary wastewater or surface runoff—such as water from kitchen sinks, washing machines, or downpipes—to feed directly into the main trap alongside the primary top grid discharge. The internal design incorporates a removable dip tube that creates an effective water seal, blocking unpleasant sewer gases from rising near building perimeters. The primary outlet seamlessly integrates with standard 110mm underground drainage pipes for a secure, watertight fit.
 
Designed for straightforward installation and easy maintenance, the gully features a wide top opening that accommodates standard gratings and can be paired with risers to adjust to finished ground levels. The internal water trap is easily accessible for clearing silt, leaves, and debris, preventing blockages further down the line. Whether you are managing surface water around a domestic extension or a commercial property, this rear inlet bottle gully delivers professional-grade versatility and efficiency.
