We have tried to drain at many locations including 2 hydrants with the same results. Not sure if the domestic has been shut down tho. It's in the same pit. I like the stethoscope idea very much. thanks

Then I would throttle the domestic, keeping some flow to push water toward the sprinklers. then, with a stethoscope or one of those fancy gadgets I'd try to pinpoint where there is flow. Larger pipe towards smaller, of course. On Thu, Sep 24, 2009 at 5:07 PM, ParsleyConsulting < [email protected]> wrote: > I'm with you on this one Ed.
