Slab Leak Repair in San Marcos

What is a slab leak?

The plumbing systems in many properties in San Marcos were installed with copper piping buried in the large concrete foundation.  Despite the fact that copper is a reliable plumbing material, cracks and holes can develop over time. The water coming from under the foundation is referred to as a slab leak. It takes time for the water to become visible since the source generally is not visible. Slab leaks can cause substantial damage. It is important to act quickly to minimize exposure to your home.

What does a slab leak look like?

If you can see the pipe, even a small leak is easy to trace. Slab leaks occur in the pipes buried deep in the concrete foundation of your home meaning that is not always visible.

How can I tell if I have a slab leak?

Although it may not be possible to see the slab leak you can use the following techniques to diagnose an unseen leak:

  1. Unusually High Water Bills – even the smallest hole in a water pipe can lose thousands of gallons per month. Check your water bill increased usage you cannot explain.
  2. Sound of Running Water – if you can hear water moving quickly through the pipes when faucets & appliances are off, you may have an issue.
  3. Moving Water Meter – If all appliances and faucets in the house are turned off and the meter is stil moving, you could have a problem.
  4. Standing Water or Saturated Ground - If a leak is left undetected for a long time, water can create a damp patch on the floor

What causes a slab leak?

While copper pipe is regarded as a reliable and long-lasting plumbing material, it can still fail. Some of the most common causes include:

Slab Leak Broken Copper Pipe
  1. Age - as a pipe gets older leaks become more likely. Our experience shows that homes over 25 years old are more likely to suffer a slab leak, but homes of any age can be affected.
  2. Incorrect Installation – if the pipe was bent or damaged when installed, problems can occur in later years.
  3. Temperature Changes - as the slab increases & decreases the pipes expand and contract. Vibration or or edges rubbing against the pipe can create holes.

Whatever the reason for the slab leak, it is important that the problem is found and repaired by a qualified plumber. This will prevent further, more expensive issues.


How can I find a slab leak?

Generally it is pretty easy to use the hot water line to find the general area of a slab leak. By using the electronic leak detector around a hot spot on the floor will help us pinpoint the location. Cold-water line leaks present a much more challenging issue to locate. Because the pipe is buried, we must use an electro-acoustic leak detection device so we can ‘hear’ where the issue is. We use specialized devices that show us with pinpoint accuracy where the slab leak is located. Finding the location of the issue is done in a non destructive way because we use the latest electronic leak detection equipment. Finding the exact location can greatly reduce the time and cost of the repair.

What is slab leak detection & how does it work?

It is important to use electronic equipment to locate the exact source of your slab leak. The flow of water and size of the hole gives the leak a unique sound at a customized frequency. Our detector locks on to the sound and pinpoints where the issue is. We don't dig up your floor to search for the problem because we can detect the sound coming through the slab. Non-destructive and non-invasive techniques are our specialty.

How do I repair a slab leak?

Once you know you have a slab leak, you have choices for repair. If the pipes are easily accessible we can make a direct repair, but this is rarely the case with slab leaks. We do not usually recommend digging up the floor to repair the leak as this can move the pipe and cause more problems in the future. Instead, a new pipe can be routed through the framework of the house isolating the area with leak.
