10mm Plastic Coated Microbore Leak?

[Crinkmeister]

I noticed a small raised area, about 50mm across, 3 or 4mm high in the wall directly above the return feed from a radiator in my sons house last night. It's a dot n dab wall which I redecorated a year ago (blown vinyl, emulsion painted) when I was refurbing the house and there was no such bulge then - I would have noticed it. Now I'm wondering if the copper has a pinhole and the escaped water is sitting between the copper and the plastic. No sign of dampness and the combi pressure is stable. If the heating is on, you can feel warmth at this point. This section of wall has been repaired at some point in the past as it doesn't sound hollow when tapped at this point. Have any of you seen this before? I'm thinking it's major mess, big hole in wall time coming up....:cry_smile:

grab a hammer/padsaw and get in and see

I would if: a) It wasnt so flipping cold, b) I hadn't recently redecorated and carpeted the whole place and c) my son, his girlfriend and my 1yr old grandson were not living there! I'm going to tell him to keep a close eye on it and let me know if anything changes. Fingers, toes and all other crossable bits (ouch!) crossed.

cut it out with a stanley to have a look you can stick a picture up to hide the hole
