A (another) picture speaks a thousand words. I guess I'll have to don my plumber hat in the near future.
Part #19?Part number 19 is a 2 lb spring check valve that will add additional head loss.

Thankfully, they didn't.There is a spring check valve that comes with the tab feeder, which would be right before the feeder if they installed it, but maybe they did not install it.
@JamesWGot pricing from PB for the Hayward and Raypak flow switches. The Raypak is in the same pricing ballpark as the Harwil, therefore i would consider either. Any words of wisdom?
Harwil $150.00 + shipping
Hayward UHXFSW1930 $266.98
Raypak 007142F $167.59
Thanks, James. I wound up finding this one. It's different manufacturer (2004) but seems to be the same flow switch. I couldn't find anything on Raypak's site.

Unfortunately another one reared its head. I found after the decking crew completed the walkway and steps foundation that they had buried an irrigation line ("funny pipe"). Although it was obviously exposed for a reason, like the others I installed and routed out of the trenches, they buried this one. There's no way to ensure they didn't damage it when they completed their work. I've tried my best to ensure I monitored this project closely to avoid any pitfalls but I've found it can be a daunting process. At this point, the PB is planning on digging under the walkway and/or steps to find the line. That concerns me a bit because I'm fearful after that's done and backfilled, there may be a void under the walkway/steps which may lead to cracking or other issues down the road.This still isn't done, wow.
Hopefully it finishes out well and no more hiccups.
