Water Line Leaks
Main Water Line Leak Detection
The main water line is the single supply line carrying all incoming water to a property. A leak here affects the whole building rather than one section of it.
What sets it apart
What sets a main line leak apart
A leak on the main line typically affects overall pressure and usage rather than one fixture or area, which is a useful signal when narrowing down where to look first.
Property-wide pressure drop
Rather than pressure loss at a single fixture.
Consistent meter movement
The meter continues to register flow with the whole property shut off.
Yard or driveway wet spots
Along the likely run of the line from the meter to the building.
