Wet patch on kitchen ceiling

View the thread, titled "Wet patch on kitchen ceiling" which is posted in UK Plumbers Forums on UK Plumbers Forums.

surely a copper pipe is a copper pipe.

I regularly get called out to a nursing home that gets pin holes in its pipe work (normally about 2am after the water has got into the fire alarms) Can be caused by just having some flux on the pipe, could just have been a slightly thinner wall on that section of pipe??

in future if you need a quick fix, cut directly over the pinhole and use a speed fit coupling

Like codcutter says a small bit of flux could be the culprit used to get pin holes on old steel pipes in boiler houses next to the cold feed coming in to the heating circs.
 
All sorted, the plumber just cut the leaky section away and used a coupling. I watched him do it and I'm confident I can do it myself in future if I ever have to.

Cheers for all your help and advice 🙂
 
I cant really tell by the picture how close the 22mm pipe is to the above flooring.Just wondered if it has been screwed or nailed from above.
Can the pipe be moved from side to side.Be careful though.
