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.
