Paragon Underground Drainage Back Inlet Bottle Gulley

Alongside its top inlet through the grid, this bottle gully has a back inlet on the side of the body opposite the 110mm outlet. This allows a waste pipe or rainwater downpipe to be connected into the gully below grid level. Water from the connected pipe enters the body directly rather than discharging onto the grid. This keeps the grid clear, reduces splashing at the surface and prevents discharge from spilling over the gully top during heavy flow.

Inside, the gully works on the bottle trap principle. Water entering from above or through the back inlet passes into the base of the body and then rises to leave through the side outlet. The water held in the base forms a seal against drain odours. Forming the trap within the body keeps the gully compact. A round grid sits in the top to hold back leaves and debris, and moulded feet beneath give a stable footing.

• Back inlet: Takes a waste pipe or downpipe into the gully below grid level, keeping discharge off the grid.
• Integral bottle trap: The trap is formed within the body, retaining a water seal to prevent drain odours escaping at ground level.
• Compact design: Inlets and trap in one body reduce the depth and space needed at the drainage point.
• 110mm side outlet: Connects directly into Paragon 110mm below ground pipework and fittings.
• Round grid: The grid at the top lets surface water through while keeping debris out of the drain.
• Support feet: Moulded feet at the base provide a stable footing for bedding.
• Recognised standard: Manufactured in accordance with BS 4660.
• Made in Great Britain: Manufactured in Great Britain by Polypipe, and finished in terracotta.
