Bottle Gullies are usually used externally alongside the house wall when introducing waste or rainwater pipes into a foul drain. They can also be used on Surface Water drains to collect rainwater from paved areas. You should always check with your local authority before connecting rainwater pipes into a foul drain unless this is an existing situation. The top section of any gully should be at least 150mm below the Damp Proof Course Level. Bottle Gullies provide a trap that stops foul odours from the underground drainage system from escaping into the air. This bottle gully is also roddable. There is a central chamber within the body of the gully that can be removed for cleaning and clearing purposes. An RS4 coupling is required to connect the outlet of the gully to 110mm Pipe. A single socket bend will also connect onto the outlet if required.Please watch our overview video below
