There is a drain in a yard which I'd like to tee into.
The image shows the drain. The "curved" bit leads to a rainwater guttering while the "straight" bit which leads into the curved bit from the right (with debris in it 'cos it's been unused for some time) is from a soil stack.
I'd like to T into the soil stack straight bit to the right of the drain to create a another soil stack.
1. The drain seems quick shallow (it's only about a foot deep as you can see. Is there a minimum depth for drains from soil stacks?
2. If I tee into the existing run that feeds into the drain, do I need to notify the water company?
