The Orange County plumbing & leak detection company that diagnoses first

Straight Flush Plumbing & Leak Detection is a family-owned, owner-operated plumbing company serving South Orange County, California since 2019. We specialize in the two problems that catch most homeowners by surprise: hidden water leaks and slab leaks in copper-era homes.

Our diagnostic-first standard means we confirm the source of a problem before we recommend a repair. That's why homeowners in Laguna Niguel, Dana Point, Mission Viejo and the surrounding cities ask us to find leaks that other plumbers were ready to tear a wall or slab open to chase.

Lance, the owner, answers the phone. You talk to the person who will actually do the work — not a call center.

Most leak detection starts with a guess and a demolition crew. Ours starts with physics.

• Acoustic leak detection: Specialized listening equipment pinpoints the sound of pressurized water escaping from a pipe — even through a concrete slab.
• Thermal imaging: Infrared cameras show temperature differences from a hot-water leak, narrowing the search area without breaking concrete.
• Electronic pipe locating / pressure testing: Confirms which line is leaking and isolates the problem before you pay for a repair.

Once we've pinpointed the leak, we walk you through the honest set of repair options — whether that's a spot repair, a reroute, or a full repipe — with real pricing, so you can make an informed decision.
