I had bought a new spout and applied teflon tape on the pipe threads,
and when I installed the spout, it gave the same result as the old
spout. One question I have is could the diverter be taking the
back-pressure when the water pressure is high and only going through
the spout? I did notice water dripping from the diverter handle when
the water pressure was high and only going through the spout.

I agree about the possible leak, but also check to be sure the spout
itself is not leaking. Many spouts have an adjustable sleeve in them
to adjust for wall thickness and pipe stub length. That sleeve might
be leaking, or maybe you just need some teflon tape on the stub pipe
threads.

I'd try the teflon tape and inspect the spout, and it's sleeve.
If it still leaks, obtain another spout and test that one. If you
still got a leak, you probably got a pipe leak. Another thing you
might try is to put a cap on the end of the pipe and turn on the
water. Then listen for leaking water. If it drips, you got a leak.
If not, the spout itself is bad.

If you are lucky, the rear of the tub wall is a closet, where you can
make an access panel. Make it permanent. A 16" square of 1/4"
plywood and 4 screws are all you need. I never understood why people
put a permanent wall behind tub plumbing. Sooner or later, there will
be a need to get to that piping.

Sounds like you may have a leak in the spout piping. When you install the
spout there is then enough backpressure to force the water out the leaking
spot. Without the spout, then isn't enough backpressure to force the leak.

Do you have any access to the back side of the tub. Like in a closet or
something. You would need to cut an opening. If its in a closet, you can
just make a nice panel to cover the cut out.

If I connect the tub spout to the copper piping and run the water
completely thru the spout; water drips to the underneath ceiling. If I
disconnect the tub spout so only the copper piping shows, and then run
the water completely thru the spout; no water drips from underneath.

Does anyone know what this could be?
