Med Temp Secondary Cooling Leaks

[THE DUDE]

Hi all,
Just wondering how fun it is finding Glycol leaks on a Pumped Secondary System in a Supermarket.
On a DX system, a hand held Leak Detector will get you into the leaking case,or at least the line up with a leak.
Pulling deck pans or kick plates checking floor drains looking for Glycol isnt fun.
Any thoughts?

just keep topping the system up and the leak should show itself
saves stripping each cabinet,checking pipe runs,drain outlets

I was thinking of a Glycol sniffing dog.
