Soil pipe IN FRANCE

[Olliellis]

Hi just a quick one. I am installing new soil pipe and it comes out the back of the toilet. I know there needs to be a fall on it. 1.23 or 1.40
The question is do i need to install an angled joiner or just tilt it in the fitting. Same for connection to soil stack.
T piece or angled joiner. There is 1 metre from toilet to stack.Thanks for your help and advice.

There will be enough give in the fittings to give the pipe a fall. Square branch and straight WC connector will be fine.
