Microphones huh window dressing for the desperate in my opinion !

I respectfully disagree. Nothing wrong with using the old Mk. I eyeballs and earholes but if the microphone can pick up something the old meaty bits can't it's still a win and the leak is found either way (hopefully!).

It's a suspended wood beam floor, depth to ground is up to 80cm in places. But the pipework is new (plastic pushfit). So just make a few traps, or is your floor lovely or laminated ? chking

It's newly fitted laminate (last 5 months). Not glued however. Not block n beam, but just wooden joists, planking and chipboards over insulation, then two thin 2mm layers of under-floor membrane (foam/plastic), then laminate on top. Sorry no diagrams available

You can buy a stethoscope off Amazon for under 5 pounds. I have used 1 for similar reasons. An automotive stethoscope is great for detecting flow in a pipe you can't access.
