I wonder if it's some kind of magnetic doohicky that's supposed to remove toxic goobers, or whatever, from the h2O? Did you check it for magnetism?

John, no I didn't think about magnets but I had the doohicky part figured out!

Looks like a home built thing.

Dude. Seems unlikely if it says "Original technology-Grunder
made in Austria" on it.

Mr. Grunder could live in Austria, maybe he's just Visiting.

My vote's for some random water hammer device. I glanced through part of what Fritz posted, but don't want to read through what was posted.... hence the water hammer guess.

In order for a water hammer chamber to work I though it had to be at the end of the runs? Perhaps it was installed to capture sediment? But there appears to be no way to clean out or open the box.
