The main line from your meter to your house can leak hundreds of gallons underground without a single indoor symptom. We trace underground water line leaks across Covina properties with ground microphones and line-tracing equipment.
In Covina, the service line from the street meter to the house often runs under driveways, landscaping, and walkways. Tree roots, soil shifting, and aging galvanized or poly pipe all cause failures. Because the water drains into soil, the indoor plumbing can work fine while the meter spins and one patch of lawn stays suspiciously green.
We start at the meter: a simple flow test tells us whether the leak is on your side of the meter or the city's. Then we trace the line path with electromagnetic locating equipment and sweep it with ground microphones that hear water escaping underground. The leak gets marked with paint, so the repair crew digs one hole in the right place.
Covina's mix of clay-heavy soil and mature landscaping absorbs a surprising amount of water before anything surfaces. Add irrigation systems that mask wet spots, and an underground leak can run an entire billing cycle unnoticed. If your Covina water bill jumped and the house shows no indoor signs, the yard line is the prime suspect.
For leaks under the home's foundation rather than the yard, our slab leak detection in Covina uses different equipment tuned for concrete. We will tell you which one your situation needs during the first phone call.
Shut off the house main valve and watch the meter. If it still moves, the leak is between the meter and the house, which means an underground line issue on your Covina property.
No. The leak is marked at the surface before any digging starts, so excavation is limited to the repair spot. Most Covina yard-line repairs need a single trench section.
Yes, roots are a leading cause in Covina. They exploit tiny joints and cracks, then widen them over seasons. Mature street trees near the service line path are the usual suspects.
The water utility handles leaks on their side of the meter. Our meter test documents which side the leak is on, which settles the question before you spend on repairs.
One call gets a Covina leak detection specialist to your door, with the equipment to find it the same visit.
