What's included in our leak detection and repair service
Every leak detection and repair job includes a full inspection, pinpoint detection, repair, and pressure testing. Here's what you get when you book with us.

Work order
Leak Detection and Repair- Full leak inspection: We check your water meter, inspect visible piping, test fixtures, and look for signs of hidden moisture. This takes 20 to 40 minutes and gives us a clear picture of where the leak is likely coming from.
- Pinpoint leak detection: We use acoustic listening equipment, thermal imaging, and pressure isolation to pinpoint the exact leak location. For slab leaks, we use electronic detection equipment that reads sound waves through concrete. You get a precise location, not a guess.
- Repair and pressure test: We repair the pipe, fitting, or fixture using the right materials for the job. After the repair, we pressure-test the line to confirm it holds. We don't close up the wall or floor until we know the leak is fixed.
- Water meter verification: After the repair, we recheck your water meter with all fixtures off. If the meter is still spinning, we keep looking. We don't leave until we've confirmed zero water loss.
- Written repair summary: You get a written summary of what we found, what we fixed, and any recommendations for preventing future leaks. It's your record of the work and useful if you ever sell the home.

How leak detection and repair works in Covina
Covina's housing stock ranges from 1950s ranch homes in Charter Oak to newer builds in Covina Hills, and each era has its own leak patterns. Older homes often have original galvanized or thin-wall copper pipe that corrodes from the inside out.
Charter Oak
Many homes here were built in the 1950s and still have original galvanized pipe. We see a lot of pinhole leaks and low water pressure from corrosion.
Covina Hills
Newer construction with copper and PEX. Leaks here are often from fitting failures or high water pressure stressing connections.
Downtown Covina
Older commercial and residential buildings with a mix of pipe materials. We handle both residential and commercial leak calls here.

PhotoSlab leak rerouted in South Hills
Before: The slab leak was under the living room, and the homeowner was worried about breaking up the floor.
After: We pinpointed the leak with thermal imaging and acoustic equipment, then rerouted the hot water line through the attic. The repair took two days, and the water bill dropped back to normal the following month. No concrete was broken.
Pinhole leak repaired in Charter Oak
Before: A Charter Oak homeowner called us when they saw water staining on the ceiling below the bathroom. The leak was from a pinhole in a copper supply line that had been dripping for weeks. The drywall was soaked.
After: We found the leak with a moisture meter and thermal camera, opened a small section of ceiling, and soldered in a new piece of copper pipe. The repair took three hours. We dried out the area and the homeowner repaired the drywall.
Underground leak found in Sunset
Before: A Sunset homeowner had a water bill that doubled and a soggy patch in the backyard. They suspected an underground leak but didn't want to dig up the whole yard. The leak was somewhere in the main line.
After: We used acoustic listening equipment to pinpoint the leak within a two-foot area. We excavated that small section, repaired the cracked PVC pipe, and backfilled. The job was done in one day, and the water bill returned to normal.
Leak problems we solve for Covina homeowners
Leaks show up in different ways. Some are obvious, some hide for months.
Slab leak under the foundation
Water erodes soil under your foundation, causing cracks in walls and floors. It can also flood your home if the leak gets worse.
Hidden leak behind a wall
Moisture builds up inside the wall, causing mold, rot, and peeling paint. By the time you see it, the damage is already done.
Underground leak in the yard
Water pools in the yard, kills grass, and wastes hundreds of gallons a day. It can also undermine your driveway or patio.
Leaking water heater or supply line
A leaking water heater can flood a garage or closet in hours. Supply line leaks spray water and cause rapid damage.
High water bill with no visible leak
You're paying for water you're not using. The leak could be underground, in a slab, or in a toilet flapper you haven't noticed.
Why Covina homeowners call us for leaks
A leak never fixes itself. It gets worse, costs more, and damages more the longer it runs. Here's what you get when you call us early.

What Covina homeowners say
We had a slab leak and didn't know it until the water bill doubled. Covina Citrusline found it in under an hour with their equipment and rerouted the line through the attic so they didn't have to break up our floor. Done in two days. No more leak, no more high bill. Worth every penny.
Called at 7 a.m. with water spraying under the kitchen sink. They had a tech here by 9 and the pipe repaired by noon. He showed me the cracked fitting and explained why it failed. Fair price, no upsell, cleaned up after himself. I'll use them again.
We manage several rental properties in Covina and use Citrusline for all our leak calls. They respond fast, give us a written report, and their pricing is consistent. Tenants are happy, we're happy. They've saved us from two potential flood disasters this year alone.
Frequently Asked Questions
Short answers for the first few minutes. The team can cover the rest.
Describe what you are seeing and we will point you to the right next step.
(626) 767-2111Slab leaks and underground leaks cost more because they require specialized equipment. If we find and repair the leak the same day, we often credit part of the detection fee toward the repair. Call us for a straight quote before we start.
The telltale signs are a water bill that jumped without explanation, the sound of running water when nothing is on, warm spots on the floor, or mold and mildew smell near walls. Check your water meter: if it's spinning with all fixtures off, you have a leak. We can confirm it and find it the same day.
Yes. We repair slab leaks by pinpointing the break with acoustic and thermal equipment, then either repairing the line in place or rerouting it overhead through the attic or walls. Rerouting avoids breaking up your floor and is often the better long-term fix. Most slab leak repairs take one to two days.
The most common causes we see are hard water corrosion inside copper pipe, soil movement that shifts underground lines, root intrusion in older sewer and water lines, and high water pressure stressing fittings. Covina's older housing stock means many homes still have original galvanized or thin-wall copper that's past its service life.
