Adding to an existing waste

[grayster]

I currently have a shower running into the waste seen in the below pictures. It did originally have water in it up to about 12 inches from the top. I am looking to add a toilet as the room only has a shower. Can I simply dig down until I can remove the square drain and slip on a new piece of soil pipe and connect up the WC. Do I also need to add an air admittance valve. At the moment it simply has a drain cover on

Please ask if you need any more info

[seco services]

you start digging then you'll need building control.

thank you seco for your standard response. BC are aware and are only coming to inspect at the end of the project. I am asking if anyone knows if I can add a toilet to an existing waste with a square drain cover and has a shower running into it. believe it is a gully trap waste.

grayster if you want to add a loo at this level it will need to have its own connection to stack use the square gully for wastes or rainwater depending
on regs locally
hope this helps
