Key Features: Angle: 45° branch from main pipeline — used to split or divert flows gently (rather than a blunt tee) which helps maintain better hydraulic flow performance. FlipHTML5 Double Socket Design: Both ends (main and branch) have sockets to accept pipes — enabling easier jointing and secure connections. Material: Durable PVC-U/uPVC, robust for underground sewer and drainage use. Colour: Terracotta (standard for underground drainage fittings). Standards: Typically manufactured to comply with BS EN 1401-1 (British/European standard for PVC-U sewer pipe systems), though you should verify the actual part’s certification for adoptable sewer use. Application: Ideal for use in gravity drainage systems (sewers, surface water, site drainage) where a branch off a larger main line at 45 degrees is required.

Industry Certified: Manufactured in the UK to BS EN 1401 and BS EN 1329 standards for full compliance and peace of mind. Frequently Asked Questions - What does "roddable gully" mean? A roddable gully contains an internal trap that can be removed or opened. This allows drainage rods or high-pressure jetting equipment to pass directly down the outlet pipe to clear blockages further down the line without needing an additional access chamber. - Can I raise the height of the rectangular grid if my paving is higher? Yes. If you need to adjust the grid to match finished ground levels (such as block paving or patio slabs), you can use a Brett Martin Gully Raising Piece (B1007) to extend the neck of the gully upwards. - What connects into the back inlet port?The back inlet can be opened up to receive a 110mm (or adapter-fitted 32mm/40mm/50mm) waste pipe from rainwater downpipes, sink wastes, or washing machine discharges.
