Can anyone help please? I have contractors who want to run pipes from rainwater downpipes into an inspection chamber that is a combined foul and rainwater drain.
The inspection chamber is a base plus a riser and the contractor wants to put the new pipes coming into the chamber at a level part way up the riser, so cutting a hole in the side of the riser, and then putting the pipes through the hole so that they finish hanging in space above the base of the inspection chamber.
Is this ok to do?
I understand that it saves them having to excavate down to the base of the chamber and finding a spare connection spigot, but is it ok to do?
