I'm not sure if it's handy homeowners or negligent contractors who are responsible, but I find the same installation defects on water softeners over and over again. The installation instructions for water softeners are pretty much the same for all the different manufacturers, so the information I'm giving here should apply to just about any water softener. Missing ground clamp All of the metallic water distribution pipes in the home are supposed to be bonded; in other words, they're all supposed to be able to touch each other. If the water pipes in the home weren't bonded, what would happen if an energized (aka 'hot', aka 'ungrounded') wire came in contact with one of the pipes? All of the plumbing fixtures and other pipes that were connected would become silently energized.

A water softener though not specifically mentioned in that code section needs a separation. It can be with an air gap, or backflow preventer. I would start with manufacturers instructions. Cross connection in this case refers to a direct connection, in any building, between a potable water system (fresh water plumbing systems including any connected water treatment devices) and the sewer/waste water system (or, simply put, the drainage system.) System installers will typically dangle the end of the softener.
