No-Hub Cast Iron Closet Bend / Closet Flange
Unfortunately, because the bend was placed too low, the black rubber compression ring does not reach the top of the closet bend opening.
So, in line with Granda Buds suggestion earlier in this thread about using lead and oakum I have the following question. It turns out a regular 4x3x3 cast iron fitting (one meant to go into a hub) will fit over the top of the end of my 3" no-hub closet bend by about 1/2". The gap between the outside of the no-hub pipe and the flange is maybe a 1/16" all the way around. Can I pack that gap with Oakum and then seal the gap with poured lead? Assuming the flange is bolted to the subfloor is this a valid option?
