3\. Connections are intended so that waste, soil, water and other
services be fully connected to each individual piece of apparatus with
required piping, unions, flanges, valves, check valves, and other needed
appurtenances.

4\. Make joints between dissimilar piping with dielectric unions or
flanges.

5\. Use reducing fittings wherever a change in pipe size occurs. The use
of bushings will not be permitted.

6\. Provide piping with unions to permit alterations, removal, and
repairs.
