I've had a new kitchen fitted and I sunk the orig water pipes into the walls to be plastered over. About a month ago I noticed that all the plaster was damp and so knocked it off to discover a joint had started leaking.
I got someone around to solder the joint. I've left it a couple of weeks to make sure it wasn't leaking before re-plastering and the joint looked fine. I checked it every day and it was dry.
Having re-plastered, the plaster is dry but whenever I dont have the heating on a damp patch grows around the joint. When I turn the heating on the patch disappears as I presume the hot pipe is drying the patch out but when I turn it off the patch starts growing again. Before I re-plastered the pipe only leaked when I had the heating on whereas it seems to be the other way around now. I presume this means the pipe is not leaking. Would damp be condensing on the pipe when the heating is off and soaking into the plaster?
If anyone could help it would be much appreciated. Thanks.
