Hello, got some 60 year old cast iron / lead jointed pipe under a concrete foundation.

Doing a residential bath / toilet drain switcharoo in Southern California

Couple questions:

- The code mentions no hub connectors can go on "fittings". Is it correct to no-hub on a 90 degree cast iron? Or should a no hub always be placed on a straight pipe?

- If the cast iron is growing little hard nodules on the bottom (calcification? decay?), should these be grinded off before putting on the nohub?

Some photos of the project:

Any advice appreciated

Old cast can be a bit iffy.
I would look for a straight section, or to remove a leaded joint and insert new ABS with a donut into the hub. I would start with new pipe with as much as you can at this point.
