I wrote a while back about an underground water leak. Well, I have
determined that the water leak is not in the feed line but is within
the structure. I was misled by a main shutoff valve that didn't fully
shut off.

So, back to the problem. I am using 120 gallons a day (5 gallons per
hour) in a house that is unoccupied. I have inspected everywhere.
There are no dripping faucets. All toilets have been shut off. There
is no visible moisture anywhere. This is a 70's "raised ranch" style
house with no crawl space. Once the water main enters from the street,
all piping is within the structure.

So where the heck is it leaking?


I had a water leak once and it turned out to be the pipe going to the outdoor faucet. If you could drain your water lines and pressurize the pipes with air, you could use an ultrasonic leak detector like the one made by Amprobe. I have one I've owned for years and it's amazing what kind of problems I've been able to track down with it. I'm not sure about it detecting the sound of a water leak but I know it will detect the sound of gas/air leaking from a system. Perhaps a rental place will have something like it? ヽ(ヅ)ノ
