Rusting iron of the old galvanized iron pipes that used to be used for water.  Not much of that remaining anymore.

Actually there is still a lot of it around, just not much in small  or new residential.

 

What about copper, brass or stainless?

  • You can buy insulation material and wrap it around the pipes. At areas that you can't reach it is important that no fresh air can get there. Fresh air will always transport new moisture. But without f

  • One important advice. Whenever you do something at the aircon always switch off the main power to it and wait a while before touching metal parts. And always use shoes that isolate you from the ground

Have not seen used for water - gas yes.  Water has been plastic for decades for residential use/feed.

I was not asking if they were widely used, I was asking about where the residue they are supposed to be full of comes from if not from the water.

 

In any event, copper is still widely used in the US and it is (IMO) much better than plastic, lasts forever and is in many ways easier to work with.

It is also often a source of lead poisoning although at a lesser scale than the previous use in USA of lead pipes.  Better most of the world is not like USA.  Copper is fine for hot water heating - not so good for water lines but was preferred due to US using central water heaters.  Here most water lines are cold only so even older plastic works fine.

Copper pipes have replaced lead pipes in most residential plumbing. However, the use of lead solder with copper pipes is widespread. Experts regard this lead solder as the major cause of lead contamination of household water in U.S. homes today.

Does the residue in pipes not come from the water? If not, where does it come from?

It sound to me as if the drain pipe is obstructed. This a common problem. I have a quick fix for this that may be useful for you @Polarizing. It works on mine,

 

I put the hose of my vacuum cleaner over the end of the pipe (outside of course) and suck through the pipe for a few minutes. I had to clear out our bedroom unit just last week and there's not been a drop of water from it since.

 

You might have to be a bit creative about sealing the hose. I use a sawn off plastic water bottle.

i  use that aluminium roofing  insect  mesh rolled  into  a  tube and  inserted  in  the  end  of the drain  pipe.

Not much rust inside galvanized pipe, a little at the joints. Most all the blockage is mineral deposits. 

 

If there were that much corrosion, why do the the hundred year old galvanized steel pipes not be rusted out from the inside? 

 

Anyway, still doesn't speak to copper, brass or stainless. 

 

PVC is great. Cheap, only requires no or low-skilled labor, lasts for ever.

If the low pressure side copper pipe is freezing up, it means the AC is not properly topped up with the refrigerant. Check the pressures or have them checked.
