The bronze stuff is used for connectors or stubs for fixtures. Also, steel and copper are not to be in direct contact with each other -- brass is used to isolate the two materials to avoid electrolysis.

Re: Pulaski and others - showerhead for low water pressure
Agreed. I cut a thicket of copper pipes out of a house built in 1928 and replaced it with a simple PEX distribution "tree", and added an accessible cut-off valve for the entire system (the existing one is about thirty feet from the access hatch in a roughly 2ft high crawlspace under the house 
). I also added an external cold tap, with its own isolation valve.
The only remaining copper pipe runs inside the wall from from the crawlspace to the laundry room. The project took me a few hours, but wriggling into and out of the crawlspace with tools and supplies, and doing the whole project lying on my back made the project more time consuming.

BTW, if one works with copper in an existing system, an essential item is stale bread.

The bronze-type stuff was in 20ft lengths, running from the basement to the 1st floor bathroom. Strange stuff. Real thick-walled too.

Thankfully the scrap value of PEX is negligible.
I've only ever seen one short length of brass pipe myself, of course apart from all the brass pipe fittings and connectors of various sorts.Just out of curiosity, how many 20ft lengths does it take to get from the basement to the first floor of Nutek Towers?

Sometimes, the street lights go out and the problem is that the underground wiring has gone for a walk. Also -- news article So, vacant houses can be at risk.

During construction, pipe and wire has to be secured or not left on site at all. I've not seen or heard of people going into crawlspaces. However, some houses in my area have antique exterior sconces sometimes go walking along with wire from the conduit.

One related instance that pops into my mind, when I was still working on my tools, we got called out to a business where they had stolen the underground utility service conductors. We replaced the conductors, had our inspection, called the utility to come back out and hook their end back in and left. All was well and good until about an hour, or so later when the utility called to ask where the conductors were? The sneaky little b******ds had come back and snatched out the brand new wire also before the utility managed to make it there!
It was almost a weekly occurrence at one point! They just didn't care that the transformers were still energized, all they wanted was that scrap money!
Needless to say. Scrapping copper is a little more complicated here these days, with fingerprints and the such needed!

I am not sure whether I am more surprised that the idiot-thief thinks the fibre optic cables have scrap value, OR that the journalist who wrote the article failed to point out that it is metal cables that have scrap value, and that glass or plastic fibre optic cables are effectively worthless.

It's the data in them cables that attracts the theifs nowadays.

Re: Pulaski and others - showerhead for low water pressure
Light travels about 1 foot in 1 nanosecond (1 billionth of a second). TV fiber optic cable transmits up to 39 mbps (million bits per second) of information on each 6 MHz band. Most TV cable systems are 760 MHz systems. Therefore the total throughput of the fiber optic cable could be as high as about 5 gbps (760/6*39,000,000 equals about 5 billion bits per second).Therefore each foot could have 5 bits of information and a 50 foot section could have 250 bits at any one time. However he only has up to 50 nanoseconds to catch any of the bits as they fall out of the cable but if he is very fast, he can catch most of the bits.
