What am I doing wrong? I've done this before without issue but this time is not working at all.
I have a 3" cast iron hub that "had" a 2" rusted out galvanized drain pipe connected with oakum and lead. I got that all seperated and ordered a 3x2 Fernco (see pics).
The rubber Fernco is 4" outer diameter and definately will not work. I looked up the part number online because I thought they sent me the wrong part (miss-labeled) but it is indeed the correct part. There is no way this can be pounded into place as the rubber is 1" thick and not pliable at all.
Why is it 4" and what should I be ordering?
Cast Iron Bell/Hub: Opening Measures 3"
Fernco Dount Ordered:
Fernco - Outer = 4", Inner = 2"
Thanks for any advice!
