No matter how you slice it, capital is a finite resource. There’s only so much
to go around and, unless it’s replenished, this capital is eventually used up.
In the mechanical trades, we have the benefit of another kind of capital which
is in the form of plumbing and mechanical codes and design criteria. We have a
legacy of research, science and the hands-on experience of all those who went before
us. Someone had to figure out the pipe-sizing charts and load calculations
which we use daily as we manufacture our product of hot showers, potable water
and safe, comfortable environments.
