Hi. I have an internal soil pipe in my kitchen which runs from the bathroom directly above. It is encased in a plasterboard box. When I took the old kitchen out this pipe is sticking out of the wall which contains the soil pipe. I don't know what it is and I'm reluctant to unscrew the end. There is a faint smell of sewerage coming from the soil pipe and often there has been an unpleasant smell coming up the sink hole. The image has come out on its side but you can see the skirting is below it. Please does anyone know what this is for and what I should do with it
