Signs You May Have a Hidden Leak


Plumbing leaks are not always obvious. Homeowners and business owners in Greater Los Angeles and the South Bay should watch for these warning signs:

Unexplained increases in your water bill without a change in usage habits—even a small drip can waste thousands of gallons per month.

Our Leak Detection Methods


Superior 1 Plumbing uses modern, non-invasive leak detection technology to locate hidden leaks without unnecessary demolition or disruption.

Electronic Leak Detection

Using specialized listening equipment and electronic amplification, our technicians detect the sound of water escaping from pipes behind walls, under slabs, or beneath the ground—pinpointing the leak without opening up large sections of your home.

Sewer Camera Inspection

Our sewer cameras allow us to visually inspect the interior of drain and sewer pipes for cracks, joint failures, and other defects that may be causing hidden leaks beneath the floor or behind walls.

Pressure Testing

Pressure testing isolates sections of your plumbing system to confirm the presence and approximate location of a leak, allowing us to make a targeted, precise repair rather than an exploratory guess.

Why Early Leak Detection Saves You Money


The longer a hidden leak goes undetected, the more expensive the consequences become. Water damage, mold remediation, and structural repairs can cost tens of thousands of dollars — far more than the cost of early leak detection and a targeted pipe repair. Catching a leak early also helps you avoid wasteful water usage and the associated increase in your utility bills.
