What We Find When You Call for Leak Detection
Leak detection is the process of finding the exact spot where water escapes a pipe, often without breaking up your floors or walls. At Corona Plumbing Pros, we locate every kind of hidden leak in local homes. That includes slab leaks under your foundation, water lines inside walls and ceilings, main lines in the yard, sewer lines, gas lines, and pool plumbing.
We only do plumbing, and we only work in Corona and the cities next to it. We are not a national chain that also sells heating, air, and a long list of other trades. Leaks are our focus. That focus lets us pinpoint the source quickly and recommend a repair that lasts, not a patch that fails again in a few months. If you suspect a leak anywhere from Sierra Del Oro to Eagle Glen, we can help today.
Pool, Gas, Sewer, and Yard Leak Detection
We find more than water lines inside the house. Many Corona homes have pools, large yards, and older sewer lines, and all of them can leak.
Pool leak detection
Is your pool losing more water than normal evaporation explains? We test the shell, the skimmer, and the underground pool plumbing to find the source. A leaking pool can waste hundreds of gallons a day and damage the deck and soil around it.
Sewer leak detection
We run a camera through the sewer line to find cracks, root damage, and breaks that leak under the yard or slab.
Gas leak detection
A gas smell is an emergency. We test the line and locate the leak so it can be repaired safely. If you smell gas, leave the home and call us right away.
Yard and irrigation leaks
Wet patches, soft ground, or a spinning water meter often mean a leak in the main line or sprinkler system. We trace it and mark the exact spot.

Warning Signs of a Hidden Water or Slab Leak
Most leaks stay hidden for weeks before you see real damage. Watch for these warning signs in your home:
- A water bill that jumps with no change in how much water you use.
- The sound of running water when every faucet is off.
- Warm spots on the floor, which often point to a hot water slab leak.
- A musty or moldy smell near baseboards, carpet, or cabinets.
- Low water pressure that keeps getting worse.
- Cracks in the floor, walls, or foundation.
- Grass in the yard that stays green or wet with no rain.
These signs add up fast. The U.S. Environmental Protection Agency reports that the average household wastes more than 9,300 gallons a year from leaks, and household leaks waste close to one trillion gallons across the country each year. Catching a leak early in your Corona home protects both your water bill and your foundation.
Same Day Leak Detection, Even on Holidays
A hidden leak does not wait for a workday, and neither do we. Corona Plumbing Pros offers same day leak detection across Corona and nearby cities. We answer calls on weekends and holidays, and we arrive the same day in most cases.
Because leaks are what we do, our trucks carry the tools to find and fix the problem on the first visit. You do not wait days for a second appointment.

Fast help that lasts is the whole point.
Our Noninvasive Leak Detection Methods
We find leaks by listening, measuring, and looking, not by tearing your home apart. The right tool depends on where the leak hides. Here is what we use and why:
Electronic and acoustic listening
Sensitive microphones pick up the sound of water escaping a pipe, even under concrete. This is how we pinpoint most slab leaks.
Thermal imaging cameras
These read temperature changes behind walls and under floors, which shows where moisture or a hot water leak sits.
Pressure and hydrostatic testing
We seal off sections of the plumbing and watch the pressure. A drop tells us which line has failed.
Moisture meters
These confirm damp areas inside walls and floors so we mark the right spot.
Tracer gas
For hard cases, we send a safe gas through the line and detect where it escapes.
Camera and line location
A small camera inside the pipe shows the break, and a locator marks its depth and path from the surface.
We arrive the same day. Call Corona Plumbing Pros.

Water Leak Detection Throughout Your Home
Not every leak sits under the slab. Water lines run through walls, ceilings, and floors, and any one of them can fail. We find and repair hidden water leaks anywhere in your plumbing. Common spots we check:
- Pipes inside walls and behind drywall.
- Ceiling leaks from an upstairs bathroom or roofline plumbing.
- Under sink and cabinet leaks that rot the wood below.
- Underground main lines between the meter and your home.
- Pinhole leaks in copper pipe, which are very common in Corona.
To find these, we use sound equipment, thermal cameras that spot hidden moisture, and moisture meters. We narrow the area down so the repair stays small and clean. Once we find the leak, we handle the light repair on the spot when we can. For larger jobs like a full repipe, we walk you through the options and give you an honest price before any work starts.

Why Corona Homes Get Hidden Leaks
Leaks are not random. Corona has a few local conditions that wear pipes down faster than in many other places.
Hard water
The City of Corona Department of Water and Power reports that local tap water is hard, with system hardness around 171 parts per million. Hard water carries extra calcium and magnesium. Over the years, those minerals scale up inside copper pipe and eat at it from the inside. This causes pinhole leaks, which we see often in homes across Corona.
Copper pipe and home age
Corona grew from citrus orchards into neighborhoods over many decades. Older homes in areas like Coronita, El Cerrito, and parts of Downtown often have aging copper lines that are near the end of their life.
Slab on grade building
Most homes here sit on a concrete slab with the water lines buried below. That design hides leaks until they reach the surface.
Shifting soil
The clay and sandy soil around the Santa Ana Mountains foothills swells and shifts with moisture. That movement stresses pipe joints under and around the home.
Heat stress
Long hot summers make pipes expand and contract. Over time that flexing weakens older joints. Corona does not deal with frozen pipes, so heat and hard water are the main drivers here.
Does Homeowners Insurance Cover Leak Detection?
Many homeowners ask if insurance pays for a slab or water leak. The answer depends on your policy and the cause. In general, sudden and accidental leaks are more likely to be covered, while slow leaks from age and wear are often not. Most policies also separate the cost of finding and fixing the pipe from the cost of repairing the water damage.
We help by giving you clear documentation. Our report shows the location of the leak, the cause when we can tell, and the work we did. That paperwork is often what an insurance adjuster needs to process a claim. We are not your insurance company, and we cannot promise what they will pay. What we can do is find the leak, document it well, and give you an honest record to support your claim. Always check your own policy for the details that apply to your home.
