A leak behind a wall or beneath a floor may show up far from the pipe that failed. Water can travel along framing or under finishes before it becomes visible, so the first wet spot is a clue rather than a map.
Look for a new stain, damp cabinet, bubbling paint, musty smell, or a sound of water when fixtures are off. An unexplained change in water use can also be a clue. These signs can have other causes, including an appliance, roof, or exterior water entry.
If it is safe to do so, turn off fixtures and check whether your water meter still shows use. A moving meter may point to water flowing somewhere, but it does not identify which pipe or fixture is responsible. Make a note of when the moisture appears and whether it changes with fixture use or rain.
We start by reviewing the symptoms and checking accessible plumbing. Finding a concealed leak sometimes requires an opening to confirm the source or complete the repair. We’ll explain what we know and what further access would involve before work begins.
If water is actively spreading, use a known shutoff only if you can reach it safely and stay clear of wet electrical areas. Call Best Quality Plumbing Services at (818) 282-5846 to talk through the next step.
