I learned something new yesterday.



I never knew that you could use lead and oakum with PVC pipe. On Ask this

Old House they were attaching a new PVC drain pipe to the existing cast

iron where it went through the foundation. They cleaned out the old lead

and oakum, inserted the PVC fitting, stuffed in the oakum and poured in the

lead. They said they had to wait at least a half hour for the PVC to cool

before continuing the work.



I assume the softening and then hardening of the PVC is what gives the lead

the bite it needs to hold.









There are fittings made for exactly that purpose, I doubt it's even

legal to use lead in plumbing anymore.

Given that it was shown on TOH, I bet you're wrong that it's not code
compliant. I agree it sounds weird, but from what I've seen on
that show, they never violate code or take a quick, unsound fix.

As to fittings made for that purpose, I can invison a female elbow,
whatever, emerging at the level of a concrete floor, where the outlined approach
would work and where it would be a bitch to tear it all out and
put in a Fernco. Not even sure that's better, because then you have
a Fernco buried under concrete. The way they did it, if something
leaks, you'll see it.
