Is this a kind of sediment trap or a valve?

[John Kogel]

Since the regulator was KaKa as well, I was able to just say "Replace leaking regulator and adjacent device". What is this object, patented by Mueller 50 or 60 years ago?

The toilet flange looks like it was built to last. Is it lead, and would it be soldered to the copper pipe?

Mueller was probably the top manufacturer of a variety of early check valves.

On a side note, great local water pressure there, eh?

Thank you, Bill. Is it a check valve or were you being careful not to say it is a check valve? []

Looking at the Meuller product list, I think it may be an early form of strainer, but there's no visible way to replace a filter, unless it can be pulled out through the bottom.

Yes, we have pressure, a big lake up in the mountains. Plenty of rain. If the pipes can take it, 90 lbs of water pressure can spoil a person. I see a lot of old houses that have never been supplied with a pressure regulator.

I imagine with the right shower head, 90 lbs ought to darn near skin ya...

Yes, it's lead and it can easily be damaged with a toilet auger if used incorrectly.

It looks like a swaged fitting. Is it soldered too? Maybe a hot process swage?
