...a little more progress on the dry hydrant installation.
As part of the boat launch concrete pours, we swiped a little bit of the concrete to finish off the intake end of the dry hydrant.

Since I neglected to think of drilling the hole for the small concrete pier required to stabilize the dry hydrant support rod, it became a "clamshell hole digger" project. I got down about 20" and hit clay that I could barely scrape with the cutting edges of the digger. This is gonna have to do...(sarcasm; it will be an excellent foundation for this little project).
The dry hydrant unit has optional holes drilled top and bottom near the end of it to accommodate a 1" diameter support rod. I wanted to use a non-corrosive metal for longevity. Stainless was too pricey. Then I searched for aluminum with elevated anti-corrosion properties. I found the best deal on-line. I picked up a pc of 6061, 1" x 144" for about $40. They cut it in half and UPS'd it to me.
We glued the final fittings, filled the foundation hole with concrete, and set the aluminum rod.

The strainer unit is supported on the rod with a hard rolled stainless strap that exhibits spring properties. PB brethren, Tom Bingham, provided helpful guidance in selecting a strainer unit that also incorporates a spring-loaded back flush end-cap.
When the concrete cures, the support rod get trimmed. The soil just below the strainer holes will be trimmed down a bit, also. Then, all the exposed PVC components get a splash of latex paint to ward off UV damage.
