Default Is there any way or product to seal a pinhole in an inaccessible1/2" copper pipe?

I've presented this before and was guided to check out the baseboard
heating register. *No leaks. *So the pin hole I guess is below the
hardwood floorboards and most likely the sub-floor beneath that. There
is a finished sheet rock ceiling in the room below with no leak
showing anywhere.


I'm hoping there is something like motor-magic that can be fed into
the hot water heating system which would find its way to the leak.


Anyone have any good ideas??? * Thanks


The Nuclear industry has a similar problem. I believe their solution
is some type of nickel bonded 'patch' technique. The patches are not
obtrusive to flow, etc. These are high pressure systems, so they're
patches are very robust.


theres a possiblity the leak is from a drain line, or roof leak
following some line , or even condensation from a AC duct.


for the OPs safety the cieling should be opened for inspection.


otherwise one day a small drip might turn into a flood when no one is
home


I've followed this thread for awhile and I know this was posted in the
past as well. *I really dont understand the whole thing. *OP says there
is a leak, yet cant see any wet areas on the sheetrock below. *Thus, how
does he know there is a leak? *I support the DIY method, but this sounds
like a call to the pros might be in order. *Cutting out a section of
sheetrock is not that big a deal, and it can be patched easy enough, but
I get the feeling this leak is all imaginary. *At no point does he state
that there is a *known* leak, or why a leak is suspected.
Seems he just
points a finger at that pipe, and says "that pipe must be leaking".


I believe in the original post he stated that the floor around
the baseboard heat is getting wet. I think he also said
something about it being in an entrance-way, leading me
to question if it was located on an outside wall and he
had ruled out water getting in from outside.

I agree it seems unusual that there could be a leak
from a pipe that is under the floor doing that without
water showing up as a stain on the ceiling below.




Unless there is a known loss of water from this cooling system, or
obvious leakage that can be seen, then it seems that the leak does not
exist, and he is just imagining it. *At no time has he said any reason
to expect a leak. *He just claims there is a leak in that pipe, and yet
sees no staining or water dripping from the ceiling below. *This just
makes no sense to me.

If I had reason to believe there was a leak and an indication of the
location of that leak, I'd cut out a small section of sheetrock and
check. *Heck, drill a 1/4" hole in the ceiling and see if water drips
out. *A dab of caulk can fix that tiny hole. Otherwise, call in the
pros, and let them investigate and inspect the system. *There are times
that the homeowner just cant take care of these things, and this OP dont
sound like the most knowledgable home repair guy.

Using sealers made for auto radiators may or may not work. *They need
enough heat to seal a leak. *Then comes the question how does one get
the sealer into the system? *There is not radiator cap to remove.
Finally, using a sealer in a car coats the radiator and engine block,
which makes the cooling of the engine less effective. *I'd think that
such a product would make heating less effective as well, which would
result in wasted fuel, thus paying a higher fuel bill. *Not to mention
that if this stuff coated the pipes, this could result in a very costly
replacement of the whole heating system.

If there is some actual sign of leakage, call the pros. *If not, quit
worrying about something that dont exist. *Then again, if this leak is
only imaginary, but the OP continues to stress over it, an inspection by
the pros would be cheaper than a psychiatrist, and he would not do
something that might be harmful to the heating system and cost a lot
more later. *Even if they charge $100 an hour, I'm sure they could
inspect the system in an average size home in an hour or less. *Maybe
the'll even tweak the system to operate more efficiently, and save a few
bucks on the heat bill. *Spend the money and call the pros, because you
dont seem to understand this problem (of there is one).- Hide quoted text -
