Hi. I wanted to expose chimney that comes from the fireplace.
Unfortunately at the top there is a copper pipe that runs across.
I have tried to test what is it connected to but no luck. It doesn't get hot nor cold when turning the taps around the house.
I would like to have it removed but how to I check that it's not connected to anything?
Without ripping open all 4 walls of course 🤣
Thank you!
here copper wire wrapped in a old wool, now removed.
Welcome to the Bunnings Workshop community @vanillah. It's tremendous to have you join us, and many thanks for your question about removing pipework.
It’s quite possible the copper pipe is part of an old plumbing system—maybe a disused hot water line or a bypass that’s no longer in service—but unless you can trace both ends of the pipe, there’s no way to be certain it’s not still active. The fact that it doesn’t respond to taps being turned on is helpful, but unfortunately it doesn’t rule out all possibilities. It may be connected to an old system or an outdoor tap.
Given it’s wrapped, there’s a good chance it was intended to carry hot water. However, one important caution: in older homes, pipe insulation was sometimes made with asbestos-containing material. While yours may simply be a fibrous wrap like hessian or similar, it’s safest to assume potential asbestos and have it tested before you disturb or remove anything.
To avoid tearing into walls, your best bet is to engage a licensed plumber. They can pressure test the line, use inspection cameras or tracing tools, and determine whether the pipe is still connected and in use. If it’s no longer functional, they can also safely cap or reroute it so you can go ahead with exposing the chimney as planned.
It’s great that you’re approaching it cautiously—this is definitely one of those situations where professional input is worthwhile.
Please let me know if you have any questions.

Thank you! I persuaded husband to to check in the roof space.
It was old gas heating system that was long gone.
Hi @vanillah,
As long as your husband has followed the copper line both ways and is positive it is redundant and out of use, then you should be fine to remove it.
Good luck and let us know if you have any further questions.
