Copper carbonate or hydroxide methinks. Good thing about your situation is that the copper you take out has enough value to at least partially pay for its replacement with PVC.

Looks like some sort of corrosion to me. What are you putting down your drains? Drano? Lye? Chlorine?

One old house I had had galvanized drain pipes, and one started to leak, as it rusted out. We had to replace about a 50' run because it was nearly totally clogged with crud that was really heavy. A ten foot section of that 2" pipe was so heavy one man had to work to carry it out of the basement. Whatever it was that built up over the years weighed plenty. The new PVC pipe was great. We ended up leaving some of the old pipe sitting up there on the floor joists, didn't figure it was worth the work to cut it up and haul it out. It's probably still there.Maybe it was the same kind of built up crud that you have, except yours turned green from the copper. I figure it was grease and food buildup over the years. (There was a garbage disposal in that sink.)

I have the same 3" copper and brass drainage system and don't like the looks of this. I'll be paying attention to find out what this stuff is.

You know by the color that whatever it is has grown from the copper. When copper corrodes it turns green(statue of liberty). So it's not an accumulation of junk from the sinks.

Also, that iron pipe corrosion is real and common. It happens on the fresh water lines too. The buildup is rust colored because that's what it is.

I say we start a game.........based on the picture of the PVC install
how many mistakes can you find on this install.
at a quick glance I see 5 mistakes.

I don't see any pvc primer used. What other mistakes do you see?

I am also curious to se what others have to say of the buildup.

T's in place of wyes, wyes are code

That is the nastiest thing I've ever seen. I've never, EVER seen copper like that.

I need an answer NOW so I can sleep tonight!

I read somewhere that water copper pipes will cause that kind of corrision if there not grounded. Just a guess but I would think so could drain pipes? I'll see if I can find the write up.

Looks like you had fixed this problem a little while ago....

Recycle that copper. I think the going rate is like $ 3.40/ Lb. That should cover the pvc

$2.60 for copper up in Bangor as of yesterday

How much for the green stuff inside?

Do you have to clean that junk out to get the recycle money?

 

[EatenByLimestone]

It depends if you want clean copper money or dirty copper. I think I'd take the dirty copper rather than clean out all of the gunk.

Scrape it out, get it really hot, smelt your own copper. sweet
