What is a Slab Leak?
A slab leak by definition is a leak in the piping under the concrete slab within the perimeter of the structure. Leaks under a driveway or under patios can also be referred as a slab leaks.
Determining The Existence Of A Leak
When we first arrive to the job site we must first find out if in fact a slab leak does exist. The first step in water leak detection is to perform a pressure test. This is done by attaching a water pressure gauge to the system. Verify that all faucets and fixtures are in the off position. Any faucets or fixtures that are dripping must be secured by either closing the angle stop or replacing the unit. At this point Blue Planet will find out the water pressure and then close the valve at the main service. If a leak is present there will be a drop in the water pressure. The existence of a hot spot on the floor does not always correspond with the actual location of the leak. Water can travel a long distance before forming a warm area. Locating a leak is a two part procedure. First locating the actual piping and then following along the located piping until the leaking section is found.
Locating The Pipe
The location of the leak cannot be determined until the location of the pipe is determined. Using the transmitter, we wire the transmitter to the piping system close to the area that we are locating. The pipe locator is then used to find the location by picking up the signal that is being transmitted through the pipe. We will mark the location on the floor using an easy clean marker or tape. Than we will trace all the piping in the area that we suspect where the leak is located. When this is accomplished it is time to pinpoint the location of the leak.
Locating The Leak (If you have a leak we will find it)
This is the critical part of the entire process. Using our electronic leak detection equipment we will listen along the marked path of the piping with a microphone to establish a reading. Our technician will than move the microphone along the path of the piping in both directions and then back to the location where the highest reading was present. If there is no difference in the levels then we will use CO2 gas through the piping system which will increase the sound level about 10 times. When CO2 is introduced to the system , it should be bled slowly so it does not damage any other piping or fixtures. The purpose is not to pressure the system but merely to create a louder sound vibration for accurate location.

Why Should I Hire a Plumber that offers Electronic Leak Detection?
It takes a combination of experienced plumbers and quality devices to pin point concealed leaks. With our modern equipment our master plumbers can locate the most challenging underground leaks and come up with the best leak repair options with the minimum damage to your property.
While it is true that leaks are more usual in older homes, newer homes could have troubles too. Poor construction and deterioration and in many cases, ground movement can cause unforeseen pipeline damages at any time. It is a good idea to find the leak before it causes structural damage that can result in costly repairs.

Choosing a Repair Method, and What It Depends On
Not every slab leak is repaired the same way. Opening the slab at the leak and repairing that one section is usually the least disruptive route when a single break is involved and access is straightforward. Where several leaks have appeared, or the line is old and corroded along its length, re-routing a new pipe around the slab or re-piping the affected run is the more durable answer. Epoxy restoration — lining the existing pipe from the inside so the damaged section is sealed in place — is the least invasive of the three, though it is not suited to every pipe or every kind of failure. Breaking up the foundation with a jack-hammer is the most costly and time-consuming approach, and it is the one we work hardest to avoid.
The least expensive repair is not always the right one. Some slab leaks carry circumstances — where the line sits, the condition of the pipe around the break, how much water has already reached the structure — that turn a cheap fix into a short-lived one. What a repair finally costs depends on the location of the leak, the method the pipe and the property allow, and the extent of the damage by the time it is found. We set out the options and what each one involves before any work begins.
Why This Is Not a Do-It-Yourself Diagnosis
Without training, time and the right equipment, pinpointing the exact location of a leak beneath a concrete slab is close to impossible. The warning signs tell you that something is wrong, not where it is. Guesswork is expensive here, because every wrong guess is another opening in a finished floor. Electronic leak detection exists so that the slab is opened once, in the right place.
Reducing the Risk of the Next One
A slab leak is rarely the result of a single bad day. Pipe under a slab fails slowly, and a few habits shorten the odds. Have the plumbing looked over periodically rather than waiting for a symptom, so a line that is starting to fail is found while it is still a repair. Where the soil around the foundation is aggressive to metal, treating it reduces the corrosion that attacks pipe from the outside. And when a section is replaced, the quality of the material that goes back in decides how long it will be before anyone has to think about it again.
Frequently Asked Questions
What is a slab leak?
A slab leak is a water-line leak in or beneath the concrete foundation slab of your home. Left unrepaired it can cause foundation damage, high water bills, and mold.
How do you find a slab leak?
We use electronic leak detection and acoustic equipment to pinpoint the leak under the slab without unnecessary demolition.
How is a slab leak repaired?
Depending on the situation we spot-repair the line, reroute it, or repipe the affected section.
What are the signs of a slab leak?
Warm spots on the floor, the sound of running water, unexplained high water bills, or cracks in the foundation.
Can a slab leak be repaired without breaking up the floor?
Often, yes. Re-routing the line around the slab, or lining the existing pipe with epoxy, both avoid opening the foundation. Which one is possible depends on the condition of the pipe, how many leaks there are and where the run sits. Where the slab does have to be opened, electronic detection means it is opened in one place rather than several.
What does a slab leak repair cost?
It depends on where the leak is, which repair method the pipe and the property allow, and how much water damage has already occurred. A single accessible break caught early is a different job from a corroded line that has been leaking for months. We locate the leak first, then set out the options and what each one involves before work begins.
How can I reduce the chance of another slab leak?
Have the plumbing inspected periodically instead of waiting for symptoms, so a failing line is found while it is still a repair. Where the soil around the foundation is corrosive, treating it slows the attack on the pipe from the outside. And when pipe is replaced, the quality of the material used decides how long the repair lasts.

Under the Slab, or Under the Floor? The Diagnosis Comes First
Not every water loss in a San Diego home turns out to be a slab leak. Plenty of the calls we take describe the same things a slab leak does, and the source turns out to be somewhere the slab has nothing to do with. One San Diego job we have written up is a leak repair in a crawl space where a leaking elbow sat behind very tight access, and the repair had to be worked from inside the unit as well as from the crawl space. That is why the first visit is about finding the leak rather than committing to a repair method: the answer changes what the work is, how long it takes and what it costs you.
Not Sure Yet Whether You Have One
If you are still at the stage of wondering, start with the symptoms rather than the repair. Our guide to slab leak warning signs in San Diego goes through what homeowners usually notice first and what each sign tends to point at. When the signs are there but the source is not obvious, the next step is our leak detection service, which is the same equipment and the same process described further up this page, applied before anybody opens a floor.
When a Suspected Slab Leak Cannot Wait
A slow slab leak and an active one are different problems. If water is moving faster than you can mop it, if it has reached drywall or flooring, or if you cannot tell where it is coming from, close the main shut-off before anything else and then call. Our guide to what counts as a plumbing emergency for San Diego homeowners covers how to tell the difference and what is worth doing while you wait for a plumber to arrive.
