What is a slab leak?

Many homes in Southern California use copper piping that is buried in the large concrete foundation slab that the home is built on. Although copper is considered to be a reliable material for plumbing, holes can develop over time in these underground pipes. These holes are referred to as slab leaks. They are a difficult plumbing issue to detect because the water can seep out slowly over time into the slab where you cannot see. It is important to diagnose a slab leak as quickly as possible to minimize further damage to your property.

What does a slab leak look like?

Holes in above ground pipes are relatively easy to locate. However, a slab leak is hole in one of the water lines that run under your buildings foundation. This means that the water itself is not always visible, instead indirect clues point to the existence of a slab leak.

How can I tell if I have a slab leak?

It is not unusual for there to be no visible signs of a slab leak, however one or more of these symptoms may suggest that you have a problem that should be investigated:

  1. Unexpectedly High Water Bills - even a small hole in your water line can lose 10,000 gallons is just one month. Check your water bill for unexplained increases in usage.
  2. Sound of Running Water - hearing water rushing through the pipes when no one is using any water is another sign that you may have a problem.
  3. Moving Water Meter - Shut off all appliances and faucets in the house before checking the meter. If the meter is still increasing when no one is using any water you could have a problem.
  4. Hotspots on the Floor - If you are walking across the floor and come across a small area that is much warmer than itís surround, you may have an issue beneath the floor. The hot water escaping from the pipe accumulates that area which sends heat up to the surface.
  5. Mold or Mildew - excess moisture within the slab can cause mold or mildew to form under the carpet or warp hardwood & laminate flooring.
  6. Heaving - when water saturates soil, it can cause it to swell and actually lift the building. A bowed or bent slab is a typical clue that this you have an issue that can cause cosmetic or even structural damage to the property.
  7. Standing Water or Saturated Ground - if left long enough, water escaping from a pipe can leave the slab into the surrounding area. If you have large wet spots in your garden or on your floor you may have a problem.
Slab Leak Repair

Slab leaks can go undetected for a long time. If not repaired it can cause permanent damage to your home. It is important to call for help as soon as you notice any unusual signs.



What causes a slab leak?

Copper piping is generally considered one of the most reliable plumbing materials, however it can still fail. Some of the most common causes include:

Slab Leak Broken Copper Pipe
  1. Age - as your piping gets older it becomes more susceptible to leaks. Our experience shows that homes over 25 years old are most likely to experience slab leaks as a result of normal wear & tear, but property of any age can be affected.
  2. Incorrect Installation - pipe that was kinked or damaged at installation can lead to problems in later years.
  3. Temperature Changes - as the temperature of the ground increases & decreases your copper pipes will expand and contract. Any rough or sharp objects touching the pipe can rub and create weakness.
  4. Soil & Vegetation - plant roots can grow around the pipe, causing stress & damage. Soil expansion & ground shift due to earthquakes can also result in damage.
  5. Corrosion - poor water quality can cause the copper piping to erode from the inside out, creating a pinhole leak that will only increase over time if not repaired.

Whatever the cause, it is important that the issue is detected and repaired by a professional team to prevent further, costlier damage.


How can I find a slab leak?

If the problem is with the hot water line in your plumbing system, then it may be possible to locate the general area by identifying a hot spot on the floor. Issues with cold water line are much harder to diagnose. We use an electronic water leak detection device to accurately pinpoint the location of even the smallest leak within the concrete slab. Modern detection equipment means there is no need to break into the floor to look for the source of the problem. Finding the exact location can greatly reduce the time and cost of the repair. This is a specialist job requiring specialist equipment, so make sure that your plumber is well qualified, experienced and using the correct detection equipment before they start digging!

What is slab leak detection & how does it work?

Slab leak detection uses specialist equipment to trace the source of your leak through sound. Leaks can have different frequencies depending whether it is from a pipe under high pressure or from a pipe that is under lower pressure. The escaping water sends out a frequency that is picked up by the detector and this is used to locate the problem. Because sound is used, there is no need to tear up the floor to search for and locate the source. The entire operation is non-invasive & non-destructive.

How do I repair a slab leak?

Once diagnosed, there are different options for repair depending on where the problem is. We do not recommend digging up the floor to repair a leak. This causes huge disruption and can even cause more problems when the excavation moves the pipe. Occasionally it will be possible to access the pipes through the floor and a direct repair can be made. More commonly, a new pipe will be routed through the framework of your house and completely bypass the problem area.
