a clogged drain led to some busted olde caste iron hubs and now I want to replace ( it is in basement ) waste pipe with ABS
what is a good way to pack joint ABS into Y hub of caste iron
as long as pipe is fixed/solid does silicone do the job or do I have to get accustomed to oakum Dwight Yokum
I’ll be down in the basement
thanks John

I would just cut the cast iron pipe and join the new pipe with a no-hub coupler. Much simpler and very minimal chance of leakage.
We have done many just like this. All you need is a soil pipe cutter to cut the cast iron.

Thanks but I did not describe my situation very well
I'm going to eliminate all cast iron except for the fact one "Y" piece that is cemented into the floor - so I'm looking to put the ABS 2" straight (male) pipe into one of the sleeves / hubs of the "Y" ( female)I'll get a good fit but am looking for what to pack the joint with?
I used to pack the joint with oakum and use the powdered epoxy mix in place of lead when doing this.
Lately, I clean it out thoroughly and use PL Premium to fill the joint. I have never had a leak either way.
I'm not sure PL is recommended for that use, but it works great!
You'll need this:

Ralph gave the link to Fernco, & that it what you need.
I fear no man & only one GOD. Me
I have used the donut many times. Works great, I lube the pvc with liquid soap. Its a tight fit.
In the OLD days Oakum was packed in and the lead was poured in at about 3/4" thick. Thicker lead was not use cause Oakum was cheaper than lead. The lead rally was not water tight until tools were used to bang it tighter against the cast iron.
Quick answer is go ahead and used the Silicone. Silicone is strong enough to keep a 300# person from rocking a toilet. Pack in some Oakum so that you can easily dig out the silicone, if you have to take it out.
and all you guys
now I will be more prepared when I really get into the replacing of all the plumbing ( waters to Pex ) and realigning wastelines
our house was a triplex back in the depression so there were three kitchens, three three three & too much plumbing in the basement coupled with hot water heat to radiators
in six feet of wall I ran into two 2" cast iron drainlines that had been abandoned - one about knocked me out as it came down on me - my not realizing it was connected to nothing at the subfloorI'm sure I'll be using the donut in the future but this time utilized two other fernco couplers in my menagerie of plumbingI was buying my last fernco as Home Depot was closing at ten tonight
lights out & thanks John
