When this happened at my place, I didnt try to guess too much. I turned off all water inside, checked the meter, and saw it was still running. At that point I figured it wasnt something small. If you are dealing with a situation like that and need help fast, get fast water line repair in Seattle with Ben's Plumbing, because having professionals handle it early saved me a lot of stress. They showed up quickly, explained what part of the line was the problem, and fixed it without dragging things out. The whole process felt straightforward and calm, which mattered a lot when water service was involved. Since then, I dont delay once I confirm it is not an indoor issue.
