In response to Re: re-packing an abs to cast iron connection
: I'm replacing a 16" cast iron riser to a toilet with abs. I'm told it's OK to use okum with mortar in the old cast iron hub.

: What is the proper amount of okum to pack onto the joint before I seal it with the mortar? I'm guessing I should leave about 3/4" space above the okum for the mortar. Is this right?

Reply:
Three quarters of an inch should be fine but I would use lead wool instead of mortar. That's what an plumbing inspector would require if a lead joint could not be poured.
