On each rear corner of my house I have a 'grey water' gully: Kitchen waste on one side, and bath/basin on the other.

Each of these gully/grids are probably 1960's in origin, ceramic with cast grids and set about 5 courses below DPC. The intended patio in that area will only be 2 - 2.5 courses below DPC so there's going to be a height difference.

What is the accepted practice here? - Replace the whole gully with something taller? Pour/fit some sort of concrete upstand/sleeve?

I'd prefer the latter as I'd rather not be interfering with the drains and digging more stuff up, but I've no idea if the second option would work, or even if there's other options I'm unaware of..

Any advice welcome..

put a concrete gully surround around them or make your own with the paving
low is better than high

Don't be afraid to stack gulley surrounds on top of one another if you need to gain that kinda height.

Thanks Both.

I measured the grid and it's 6" or thereabouts, and the outer ceramic 'pot' is 8" across.

All I can find online is something called a 9x9" gully surround, which looks like what i'm after, but I've no idea how that is sized - inner or outer dimension?

Alternatively, I could cut some old slabs and mortar them into place around the gully I guess.

I managed to chain-drill and chisel around the existing unwanted concrete around the kitchen gully leaving the original concrete as a surround. The other gully wasn't so lucky, so will need something fabricated.

A modern square gulley riser should stack on top easily. i have done this in the past. You just need to make sure you can still reach the base of the gulley and into the u-bend to clear it if necessary.

As said by the others making a surround with setts or paving is usually the nicest looking.

Waste water gully too low? - 150mm below paving
