Thanks for the ideas. Bit more info. The house and the water line are less
then 5 yrs old. Located in central oregon on high (4000') plateau- ain't no
grass there this time of year. Closer to a desert climate (9" rain/yr) . The
water company has been pulling some shenanigans when it comes to the water
bill after losing a court case regarding billing. Something tells me that if
he went to them and asked them to borrow a listening device the result would
be nill. Was also wondering if the water line when layed , would likely be
made in regular lengths- thus the joints -spaced (hopefully) regularly would
be the most suspect areas. Again, thanks for the responses. Pat
