I have been advised by Scottish Water that they have detected a leak in
the mains supply feeding the flats I live in..They say it is after their
stop tap and is ,therefore ,the responsibility of the owners ..The supply
pipe is below cement and or tarmac.
Does anyone know if plumbers have sonar type equipment that can pick up
suck leaks to identify where the leak is to avoid costly investigative
digging ...Scottish Water suggested that some plumbers would have this
equipment .

ask them???
