Hi all,

We are trying to reroute our drainage. We have a manhole at the front of our house within our boundary. See picture below.

It has two openings on top of each other. Plumber said he has never seen something like it and wants to know where the two leads. Wants us to get drawings from water company.

Has anyone else seen something like this before?

And how would you advise on connecting another waste pipe to it?

My Plumber said we could add a T just before this box and to have another inspection chamber.

Any help / advice would be much appreciated
