I saw your follow-ups but for the record, reasons pipework could start
leaking include:

1. some corrodible pipework has corroded through

2. a fluxed but un-soldered joint has dried out

3. something else neither you nor I have thought of ;-)


Thank you, there are all intersting possibilities. For good measure
the second plumbver also wandered all over the place with a sniffer
but found nothing. Tyhree's no smell of gas anywhere, including under
the floor.
