I'm working on a house for resale. After removing the entryway carpet
I found hardwood floors in pretty good skape. However, the are two
strips where the seams and butt joint are damp to the touch and the
only water source close by is a hot water baseboard heating register.
But the copper pipe from the heater goes down under the floor. I can
only assume that there might be a pin hole leak in the copper that
when under pressure releases some water.

Problem is... the ceiling below is completely finished in so there is
no access to the heating pipes. In fact I can't even be sure this is
the cause but its my assumption.

I'm writing for suggestions as to what the best method for repair
would be?

I'm thinking if I cut one end of the wook strips which are in a hall
closet I might be able to pull up the two wood stips. But, there's
got to be a subfloor unther the flooring stips. I supposed I could
cut out a section of that to see if I can see the pipes, etc., etc.,
etc. You get the picture b now.

Any suggestions as to how I could approach this problem?
Thanks

There are 'leak detectors' available. From memory, they are expensive
sono microphones that listen for the 20+kHz scream of a leak.

Again, from memory, used in the oil industry. Nondestructive testing
instrumentation. Name Halifax, or Halligen comes to mind. [too lazy
to do search]

I actually own an ultrasonic leak detector. It can detect the sound of
the ridges on the skin of my fingers rubbing together lightly. My keys
being barely shaken sound like wind chimes in the headphones of the
detector. My detector was designed for find refrigerant leaks but has
many other uses. Dye that glows under UV light is used to detect leaks
in refrigeration and cooling systems. I wonder if the products designed
to stop leaks in vehicle cooling systems could be effective in stopping
leaks in hydronic heating systems?
