Several years ago we could hear water running but it wasn't in the
house, nor was it any of the hose bibs. Our water supplier has a set of
hydrophones (I think that's what they called them) that they loan out to
customers. Basically the set has a solid disk connected by surgical
tubing to a stethoscope like head set. and all contained in your
standard 1960s oak case. You put the disk -- or maybe it was a pair of
them -- on the ground and listen for where the sound of the water is. It
didn't work for us because the leak was right at the foundation where
the old galvanized pipe enters the basement. But something like that
might work for you. I have no idea if the Portland Water Bureau has
anything like that to loan to customers but it wouldn't hurt to ask.
