Leak Detection & Water Leak Repair in California

Electronic leak detection that pinpoints hidden leaks behind walls, under floors and underground.

About Our Leak Detection & Water Leak Repair Service

A hidden leak can run for months before it shows up as a stain, mold or a shocking water bill. Our California leak detection technicians use acoustic listening equipment, thermal imaging and pressure testing to find leaks precisely — so we open one small spot instead of a whole wall.

From a pinhole leak in a copper line to a broken irrigation main, Coco Plumbing Systems handles water leak detection and repair across California. Once the leak is found, we can usually fix it the same visit.

  4. Open a small access point and repair
  5. Test and confirm the leak is gone

Leak Detection & Water Leak Repair FAQs

How do I know if I have a hidden water leak in California?

Turn off every faucet and appliance, then watch your water meter. If the leak indicator moves, water is escaping somewhere.

Can you find a leak without tearing out walls?

Yes. Electronic leak detection lets us pinpoint the leak so we only open a small area.

Is a water leak an emergency?

Active leaks that are causing damage are. Shut off the main and call (888) 480-9811 any time.

Do you fix the leak too?

Yes. We repair the leak once it's found, usually the same visit.
