Soil stack change

[T & H Plumbing]

Hi guys please see below picture, it has the soil stack going into the floor and connecting underground, my question is can i cap this off under the floor concrete over and drill a new horizontal hole thru the wall above ground and connect to the stack that way, leaving the branch under the floor? or would this be going against regs n stuff? digging it out and making it good will take a lot of work so was just wondering advice would be great thanks

Use a 4" rubber bung to make the redundant pipe watertight first, then fill with concrete/cement and make good floor, if you just use compo and there is a blockage at a later date, you'll get damp up through floor

They're a temporary fitting imo. Mainly used to block a waste for testing or clearing.
