What part do I need to raise this gully?

I've been left with a gully that isn't high enough for the level of our patio, see photo. It needs to go up roughly another 200mm.

The end of the gully is male, going into a socket in the pipe below:

The gully is made by Aquaflow. The pipe diameter is 160mm.

I can't seem to find a single-socket adapter made by them. The only option I can see that looks like it will definitely work is to buy a 3m pipe with a single socket and just use the first 0.2m of it. Seems very wasteful.

I can also see a double-ended adapter, not sure of the exact length but perhaps it would work to cut the pipe just above the level of the bottom adapter??

I'm assuming that buying a part from another manufacturer might well not fit?

One of these. Universal Roddable Gully 160 x 400mm Riser | Toolstation Looks like you may need to Solvent weld the Hopper into the riser, then trim riser to suit. Don't forget to chamfer the cut edge to 45° before trying to insert it back into the socket, or you''ll displace the seal. (Scrape off any residual lubricant from the Hopper spigot and put that on the cut end before gluing, will aid reassembly.

I cant tell from the picture, but bear in mind the waste pipe needs to be long enough to discharge below the grid, but above the level of the water in the gully.

Thanks that is very helpful!
