You take the cake----Ten knowledgeable folks (pros--a building inspector --two bath remodlers and a handful of plumbers) tell you not to worry.

You want to worry so you keep posting the same question ---

Finally one person tells you what you wanted to hear--and off you go --
The sky is not going to fall.

Plumbers flux is water soluble and is washed out of the inside of the pipe--
any on the outside could be washed off with soapy water. (as I suggested earlier)


Oh,well----Mike---

Actually, internal flux corrosion is the cause of tens of thousands of pin hole leaks in copper pipes every year.

This is backed up by the copper development association's studies and several independent studies as well as my own (being a master plumber/plumbing contractor with over a decade of specializing copper pipe leak detection, repair and repiping). But hey, what do we know.

"plumbers flux" is not all water soluble as you claim. In fact, the overwhelming majority of flux on the market for the past 100 years has been oil soluble not water soluble. Only in the past 5 years or so has the use of water soluble flux become a bit more common. Even now, it's probably close to 50/50 with oil base coming out ahead.

Protech---You got blind sided here----She has had 4 different posts on this subject---Her description was typical of surface oxidation caused by flux.---Nothing extreme or any indication of failure.

She is looking for the answer that she wants to hear.

She finally heard it. ---Mike----

Thanks. Some water just eats up copper----several counties in Arkansas banned the use of copper for that very reason.---Mike---

Copper Pipe Turning Green


I am not sure hw to post on this site so everyone can see my question. So I am sending this one and hope everyone can view this. I found out why my pipes are turning green. I was storing chlorine tablet in the basement they were not wrapped and got wet so that is what caused the pipes to turn green. But now I need to know how to clean them, I tried soapy water baking soda several cleaners. Can someon help me.
Thank you

That looks rather nasty---How old? Any other signs of deterioration elsewhere in the house?

Are chemicals stored near by those pipes?

Looks like chemical damage to me---

they are about 13 years old.... now that you mention it... there were some pool chemicals stored on a shelf above them and I do believe some may have leaked... should I clean (if so how) or replace?

I though it looked like chlorine damage---

Clean it up with an S.O.S pad---if there is really deep pitting--then think about changing the pipe--if not--you are good with the existing stuff.

Cold pipe sweating along with the pool chemical fumes is the likely cause. If it is not leaking I would not be concerned. I would store the pool chemicals elsewhere though.

Great stuff but if you don't wipe afterwards, the pipe goes a deep green pretty fast.
