Asbestos soil pipe

[brum_screwdriver]

I can't find any recent threads about partial/total replacement of asbestos soil pipes... 10-15 years ago people were merrily cutting pipes with hacksaws etc. Have people been (wisely?) scared off by the risks? I have a pipe that is leaking, and would appreciate thoughts on options (will post specifics shortly).

Hopefully.

Depends on the nature of the leak and where it is.

There's a hole or crack in the section shown in red. Replacing the whole pipe means lifting up part of a new patio. I'm hoping to replace one section of the old pipe (assuming there is a way to interface new pipe with old).

That pipe going through the wall is possibly lead, if it’s leaking when toilet flushed, might just want the seal re-doing, using sand/cement, sealant et al.

What is the best way to test what material it is, without scratching off asbestos dust?

There's actually a small hole about size of a pound coin half way along the pipe. Will get up the ladder this wknd to investigate!

A magnet will stick to lead metal or cast iron and not asbestos

I'm not convinced a magnet will stick to lead!

A knife will leave a shiny metal incision/surface on lead, a magnet will stick to cast.

I'll probably get slated for this but - it's outside and you don't need to smash it apart, just scratch it a bit; unless you put your nose right up to it and try to inhale anything that comes off as you scratch it, you'll be fine.

when I painted my asbestos soil pipe I used paint stripper rather than sanding.
Asbestos is horrible stuff to paint as it creates a fluffy skin over time that paint won't stick to.

I guess some kind of epoxy might work? or a fibreglass bandage ?
I'd interfere with it as little as possible.

It'll be asbestos - lead bends etc. were used on C.I. stacks. I'd wrap it with denso . A repair that's coeval with the pipe

 

[Hugh Jaleak]

Repair with Denso tape would be the first choice, (it's filthy stuff to work with so wear some decent rubber gloves that you're happy to throw in the bin afterwards).

If that isn't practical, and you need/want to replace, I'd look to cut it off at a suitable point and use a Flexseal type coupling to make a joint. Wet the pipe, wear a suitable dust mask, use a hand saw, keep the cut wet as you go and the chances of any dust causing an issue should be pretty remote. Replace as required with plastic.

No, absolutely, just having some brain fog of late

another one for just wrap it with denso will last for years and years before a re wrap

Just watched a skill builder video with a sent in question and photo and thought "I'm sure I've seen that before somewhere"
