Black soil stack help

[plumbdoctor]

Hi my knowledge of waste is very basic I'm going to a job I went to a while back that has a waste pipe that's black it's not plastic, clay or cement type it runs from the roof all the way down internal connecting to all waste appliances just wondered if anyone knows what it's made of ?

Looks like it's rusting ... So cast?

 

[plumbdoctor]

It's not cast iron it's been cut with a hole saw by someone the soil stack is copper and this is just the bit that comes through the loft and vented through the roof

 

[plumbdoctor]

Any answers on this ?

 

[Whyme]

Copper soil stack ya say. i'll take that away for free and give you a plastic one as a gift. i think that bits asbestos.

 

[plumbdoctor]

Could be clay, mums house has one. Council or ex council

It does look like its rusting?? Cast iron?? and you can drill cast iron with a hole saw!! I had to as an apprentice! slow and steady with a new good quality hole saw!!

Did they used to us pitch fiber for soil and vents??

 

[plumbdoctor]

It's ex council I didn't cut it just a bit worried it was asbestos someone tried to attach a strap boss to it why it's leaking
