Blocked Copper Pipe

adshiel · 16 May 2005

We have an Air Con system in our flat and the drain away is a 22mm copper pipe under the floor. It seems to have become blocked (not sure really how) and I can not clear it with a pipe cleaner. Any ideas how to clear the blocked? Will a acid drain unblocker harm the copper?

What does it say on the tin/bottle ?

It doesn't say DONT use on copper pipes.....

and the website for 'More Safety Information' is 'Domain Name Reserved'

Poured it now and pipe seems fine..blockage still seems to be there though.

Hydrochloric WILL attack copper, suplhuric doesn't, much.
Dunno what comes out of aircon to block the pipes. If it's limescale, supermarket descaler should be ok.
