    Hi All,

    I have some copper pipes that were plastered into a party wall and developed a leak about a month ago. The pipes have since been dug out of the wall and have been replaced with new copper.

    I have a plasterer coming next week to seal the new pipes back into the wall. To prepare for the plasterer, today I covered the pipes in gaffa and sealed where the tape wouldn't go with expanding foam.

    All was going fine until I got to the worktop level and had to remove the worktop to gaffa the pipe.

    I noticed that the pipe below the worktop level was wet.

    Is this condensation or do I have a leak in the new pipe? The old plaster around the pipe was wet and probably still is a little.

    I can see that the new pipe have been places over a little piece of metal sticking out of the wall. I hope she wet is condensation and the metal hasn't punctured the metal.

    I have had a small dehumidifier running in the cupboard below the worktop for the last few hours and the pipe is dry.

    Thanks

    Condensation would be more like a mist covering , a leak would likely show a downward narrow pathway. Can you post pics ? If its condensation ,once you dry the pipe it wont reappear for quite some time. A leak would be apparent quite quickly on a pressurised pipe.

    I would have to take the worktop off to get a picture so don't think that's possible at the moment. I had the little dehumidifier on in the cupboard overnight and managed to get my hand in this morning to touch the pipe. All seemed dry. Do you think that rules out a Leak and that I'm good to go with plastering over?
