Cast iron soil pipe jointing method

[Sharp Point]

Evening all, I’ve been asked to replace a cast iron stack on a listed building. The customer has ordered the required materials, I’ve just got to install it. What’s the modern day method to seal the joints?

Thanks

Old fashioned way for me.
Caulk it and lead it.

Up my way in Lincolnshire,old cast iron joints seem to have a cement type joint. I’ve never come across a lead filled joint

I pulled down a cast stack today, you could have had that. I cracked the seems with an sds chisel and they were just putty like all the rest I've seen.

Timesaver heritage is what i would use a lot less hassle. Cheers kop

Caulk it, Lead it, Putty n paint to finish for me personally.
You'll enjoy yourself!
Use original style Cast Iron with ears and fix it using 6" Spout nails and Bobbins.

It's an old skill that should never be allowed to die and this is your opportunity to keep it alive.

For a real old fashioned authentic job you could do it off a rickety old wooden ladder. Take the existing ones down with trembling knees, sweat on your brow and spiders climbing about on you. Then use a raking out chisel and wooden wedges to fix the new one back.

However, this is 2018 and that is no longer allowed as you know.
When you're doing it though, give a minute to think of the old timers who worked with that stuff all day everyday, off a rickety old wooden ladder.

Or lower it down on a hessian rope to the young lad who'd put it in the 2 wheeled cart, that's the cart he's sleep under at night..

Right, I’m going to lead fill the joints. Would a big blow torch and an old steel pan be anough to melt the lead?

That’s the way the old fella taught me along with huge lead snowboxes with fancy details

Yes it will be ok but I would fill up with map gas rather than propane it will get the cast hotted up ready to receive and make the pb flow better and don’t breath in ⚒

Listed building that's why they need cast
