A pinhole leak in copper, a corroding galvanized line, or a pipe that split after a freeze rarely announces itself loudly at first. It shows up as a damp spot on a wall, a drop in water pressure, or a small stain that keeps coming back in the same place.
If a pipe is actively spraying or flooding, shut off the water at the main and, if it is near anything electrical, stay clear of the area until the water is off. A slow drip or stain is not an emergency, but it is worth calling about before it turns into a burst pipe.
