A bottle gully is used to enable additional connections to be into the drainage system.The most common application for this fitting is alongside the external wall of the house, taking waste pipes from the kitchen into the foul drain.The waste pipes should always terminate below the grid, which can be cut to accommodate the waste pipes. Our bottle gullies are available with circular and rectangular top grid options.Our bottle gullies are trapped to prevent drain smells from escaping, and are roddable via a central removable chamber.Please watch our overview video below
