pvc to cast iron hub using fernco-can't get it!
I use faucet grease.
Sometimes one or two hits and slips right in other times I really have to pound to get it to go in. (That just sounds so wrong)
I had on one time where I had to hold the 2x4 and have my helper swing the hammer.
If you make a 30 to 45 deg tapper on the end of the pipe it really helps. Also 5" isn't long enough. Use at least 8-9"
