I have a soil pipe, which runs up the outside of my house, and wish to connect a new bath sink and shower waste to it.
I am not sure what it is made out of, it is the original pipe fitted to the house, which was built in 1965. It does ring when you tap it, and I originally thought it was made of cast iron, but looking at it further it appears to be made of something that is not metal. I am concerened that it is Asbestos Cement, hence why I dont want to drill without being sure.
Is there any way of determining what material it is made of. The pipe appears black in colour, but some of the more weathered sections are a light grey colour.
Any advice would be greatly appreciated.
