What is included in Leak Detection And Repair
Every leak detection call includes a system pressure test, a camera or acoustic locate, and a written summary of what we found.

Work order
Leak Detection And Repair- System pressure test: We attach a pressure gauge to your main line and isolate the house from the city supply. If the gauge drops, the leak is inside. If it holds, the leak is in the yard line. This step takes about 20 minutes and tells us where to focus.
- Camera and acoustic locate: We feed a leak detection camera through the suspect line or use acoustic listening gear on the slab. We mark the exact spot with tape so you can see it. This is what keeps us from opening the wrong area and wasting your money.
- Written findings: You get a written summary of what we found, where it is, and what it will take to fix it. We include photos from the camera when relevant. You can use this for insurance claims or to get a second opinion.
- Repair and pressure test: Once you approve the price, we cut out the failed section and replace it with new copper pipe or PEX tubing. We use SharkBite fittings or a soldering torch as needed. Then we refill the system and watch the gauge for 30 minutes to confirm the repair holds.

Leak Detection And Repair Gardena CA is the process of finding water where it should not be and stopping it. We start with a pressure gauge on your main line to see if the system holds. Then we bring in a leak detection camera or acoustic listening gear to trace the sound of escaping water.

Our leak detection and repair process
You get a clear sequence from the first phone call to the final pressure test. No mystery, no surprise charges.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
This amplifies the sound of escaping water so we can trace a slab leak or in-wall leak to within a few inches. It is how we avoid breaking open the wrong spot.
We attach this to the main line to test whether the system holds pressure. A dropping gauge tells us the leak is inside the house; a holding gauge points to the yard line.
We use this to inspect sewer and drain lines for root intrusion, bellies, and breaks. It records video we can show you so you see exactly what we see.
High-pressure water scours grease, scale, and roots from the inside of pipes. It is safe for copper pipe, PVC pipe, and ABS pipe when used correctly.

How leak detection works in Gardena
Gardena's housing stock ranges from 1920s bungalows to mid-century commercial buildings, and each has its own leak patterns. Older homes often have original copper pipe that develops pinhole leaks after decades of Gardena's hard water. Newer construction uses PEX tubing, which is more flexible but can fail at crimp fittings.
Gardena Downtown
Many homes here were built in the 1920s and still have original copper pipe. Pinhole leaks are common in the hot water lines.
Rosecrans
The mix of residential and commercial buildings means we see both slab leaks and irrigation line breaks. We carry gear for both.
Hollypark
Post-war tract homes with slab-on-grade foundations. Slab leaks show up as warm spots on the floor or unexplained high bills.

PhotoSlab leak under a Hollypark home
Before: A homeowner in Hollypark noticed a warm spot on the hallway floor and a water bill that had doubled over two months. We ran a pressure test, confirmed the leak was inside, and used acoustic gear to pinpoint it under the slab.
After: We opened a two-foot section of the slab, repaired the copper pipe, and pressure-tested the line for 30 minutes. The bill returned to normal the next cycle, and the floor dried out within a week.
Root intrusion in a Rosecrans yard line
Before: A property manager on Rosecrans called about slow drains and a soggy patch in the yard. We ran a sewer camera and found roots had entered the PVC pipe about 20 feet from the cleanout.
After: We cleared the roots with a hydro jetting machine, then repaired the cracked section with new PVC pipe. The drains flowed freely, and the soggy patch dried up within days.
Running toilet in a Gardena Downtown rental
Before: A landlord in Gardena Downtown had a tenant reporting a constantly running toilet. We inspected and found a worn flapper and a failing fill valve.
After: We replaced the flapper, fill valve, and wax ring in under an hour. The running stopped immediately, and the next bill dropped back to normal.
Hidden water leak problems we solve in Gardena

Water under a slab can undermine the concrete, cause cracks in walls, and raise your water bill for months before you notice.
Root intrusion in the yard line
Roots find the moisture in your sewer or water line and grow into it. That causes slow drains, backups, and eventually a broken pipe.
Running toilet wasting water
A running toilet can waste 200 gallons a day or more. That shows up on your bill fast.
Low water pressure from a hidden leak
A leak in the main line can drop pressure to the whole house. You notice it in the shower first.

What Gardena customers say
Our water bill doubled in two months and we could not figure out why. Gardena Plumbing Pros came out, put a gauge on the main, and found a slab leak under the hallway. They marked the spot with tape, opened a small section, and repaired the copper pipe. The bill went back to normal the next cycle.
We manage a four-unit building on Rosecrans and had a leak in the yard line. The crew ran a camera through the line and found root intrusion about 20 feet out. They cleared the roots, repaired the PVC pipe, and pressure-tested it. No more backups, and they cleaned up the yard when they were done.
I heard water running at night when everything was off. They came out the same day, used acoustic gear to trace it to a pinhole leak in the wall behind the bathroom. The repair took about three hours and they tested the line before they closed the wall. Honest pricing and no mess left behind.
