Is it ok to drill and tap the side of a tee or pipe to
Install a new main vent ? I was going to come out of the side with a L formation.

Thanks
Bob

    It has been done but it is much better to drill into an elbow ot Tee. Much thicker walls.
    They do make steam rated saddle clamps where you drill your hole, in the pipe, the saddle clamp has a hole in it that sits over the hole in the pipe and there is a steam rated rubber gasket between the saddle clamp and the pipe to keep it from leaking.
