I have 4" cast iron and will use a coupler from fernco or home depot to jooin up the 4" cast iron but what do I use on the 3" pvc im adapting to? i am going to 3" pvc. So is that where I need an adapter tommytman? Nothing is easy around this 65 year old house. While I was taking apart the bathtub I found a post card from march of 1943written from the roosevelt in new orleans. Trippy eh? It was in calligraphy.

Hey Eb.
Ya want easy? 4" No-Hub Band to the pipe you cut the hub off. 4 X 3" PVC bushing to the No-Hub Band and a piece of 3" PVC to the bushing. Now that's easy! And the bonus is that you'll have a ridged connection instead of one that floats. Sound like a plan? Tom

Thanks man I hope it don't leak or I'm ed
