re-packing an abs to cast iron connection
Posted by Chris Oxford on April 07, 2004 at 15:33:38:
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?
