The Underground uPVC Bottle Gully Square Top Adaptor is a specialized drainage component designed to connect surface water gully grids and hoppers to below-ground drainage networks. Manufactured from durable, high-impact unplasticized polyvinyl chloride, this adaptor is engineered to withstand heavy external soil loads, ground movement, and exposure to weathering. It provides a robust and reliable transitional link, ensuring that surface water runoff from yards, driveways, or patios is securely channeled into the subterranean drainage system.
 
Featuring a precision-molded square top opening, the adaptor easily accommodates standard square gully gratings or hopper heads, while the outlet securely integrates with standard 110mm underground drainage pipes. Its secure push-fit or solvent-weld connection points (depending on the specific setup) ensure a watertight and stable junction that prevents leakage and protects the surrounding foundations from water infiltration. The smooth internal transitions promote efficient water flow and help prevent debris from snagging in the connection.
 
Designed for ease of installation in both residential and light commercial projects, this bottle gully adaptor simplifies the connection between surface drainage and sub-surface pipes. By facilitating effective debris separation and smooth water discharge, it helps maintain a clean, efficient, and low-maintenance surface water management system.
