My fresh water line connects to the "city" at a meter about 1/4 mi from my
house. The water line leaves the meter which is underground and then runs
up to my house underground. I guess I own everything from the water meter
to my house.
If the water line develops a leak somewhere on my side of the meter I think
I have to fix it.
My question is: How could I find where the leak is? Do I have to start
digging from the meter all the way to my house until I find it or is there
another way? Because of the nature of the soil, depth of the pipe and
proximity to the ocean, I feel pretty sure that water from any leak would
not be seen at the surface. Is there some fancy device that could be used
from above ground that might sense the leak? I think the pipe for the
water supply is PVC.
There is an outfit specializing in this sort of thing using high power
microphone. Try to find one in your area or city may find it for you
even if it's not their jurisdiction(to prevent wasting water)
Dig till you find the line at the appx mid point and place a shutoff there.
IF it keeps leaking, then you know to move on towards the meter........If
not, then you move on towards the house..........
Unless there is an obvious probable location (ground shift from cars running
over it etc), as others have suggested, it might be best for a pro who has
the necessary tools and experience to find the leak, although my guess is if
there is indeed a leak I'd want to replace the whole thing to be reasonably
sure it didn't happen again in the near future. I was just trying to
possibly help you avoid an unnecessary service call.
I agree with John. First determine if you actually have a leak, as he
said. No sense doing all the work if there is no leak. If you
do,have a leak, it usually does come to the surface, but not right
away. Of course that sort of depends on the type of soil and whether
it's flat or a hill, and other things. It also depends on the size of
the leak. A few drips an hour would not show up much, but a gusher
would most likely cause an eruption to the surface or eventually a
sink hole. To find the actual leak could be tricky. I do believe
there are devices that sense it, but of course the average person dont
have that stuff. I dont know how deep your pipe is, but if you can
get a rough idea, maybe take a piece of pipe and drive it into that
ground every 10ft or so (being careful not to go too deep and puncture
the line). When you pull your pipe out, see if its saturated. You
might also create a path for water to follow to the surface. Be sure
to find out if there is anything else down there, such as a gas pipe
before you do this.
that's not what he asked. he asked how too locate the leak. Call a few of your
local big plumbing co.s .many have the service available. I think they use
something similar to an ultra sound ( dr. looks at the unborn fetus)

They're more anxious to display their abilities than they are to
make certain they understand the problem. Reading comprehension
is a lost art in this country (US), I think.
they can actually put a camera down any size pipe and look for leaks. You
could shut off at the meter and try running compressed air thru the pipe and
see if you can hear air hissing out somewhere also would be easy way to
check for leak between meter and the house.
