Welcome to the first video of the two part video series about connecting different pipe materials.
Up until the late 1970’s, we were still required by New York City Plumbing Code to use extra-heavy cast iron bell and spigot pipe for building house drains and soil stacks. Extremely labor intensive and just plain hard work with, you had to be in extremely good physical condition to perform this type of work.
To this day I still wonder how I did it! When no-hub service weight cast iron pipe was finally permitted, it changed everything. The material itself was less expensive than its predecessor and the labor savings was astonishing.
Instead of packing a joint with oakum and pouring hot lead to form the joints, it was now done with what we call no-hub couplings. A simple neoprene inner gasket followed by an outer stainless steel corrugated band which included two band style straps that get tightened to 60 inch pounds of torque.
Compared to the old way of doing things, this was a cake walk. Not only was fabricating house drains and soil stacks a breeze, but the manufacturers started making specialty clamps that you could use to connect different pipe materials.
Different pipe materials all have slightly different diameters and these specialty clamps compensated for the difference making the installation bullet proof.
I’ll tell you what, check out part 1 of this two-part video series above and I’ll catch up with you in part 2.
