What’s the white pipe already on the right?

 

[domenico]

It comes from the boiler. and it drains straight into the gravel not really connected to an actual drainage

Need to take the cover off and post a pic of the inside of the chamber please. Then be prepared to do some digging.

There it is. I used all the taps in the house and flush the toilet , and looks like they don't use this drain.
this is just for the kitchen
I have been told to drill a hole on the side of the chamber, for a 40mm waste pipe.
because the only thing that will pass in the pipe is soapy water at the most, the fall i have to give is not that much.
then fit an elbow & a downpipe to almost reach the bottom of the MAC, that is to avoid any splashing noise.

Is it a rainwater drain?

As you can see from the picture the kitchen is behind that wall and that is the only thing of the house connected to it .
