Slab leaks can be difficult to detect.


Leaks in pipes under your sinks or in those that connect to various appliances or plumbing fixtures in your home are usually easy to find. However, a slab leak can be difficult to discover, and this is problematic because such leaks can cause expensive damage to your home. Here’s what you should know about slab leaks.


The 411 on Slab leaks

Homes that are built on a slab foundation are at risk developing slab leaks. When these homes were built, hot and cold-water pipes were laid below or within their concrete slabs. Any type of plumbing leak that occurs underneath the slab foundation is considered a slab leak. When this type of leak occurs, it puts your home at risk with the severe damage that it can cause. Slab leaks can cause high humidity and mold growth throughout your home that can also jeopardize the health and comfort of your family.

Causes of Slab Leaks

There are several reasons that slab leaks could occur at your home:

  • Poor quality pipes might have been used during the construction of your home.
  • Pipes were damaged or improperly installed.
  • Your water is too acidic, which can eat away at your water pipes from the inside out.
  • Water pressure is too high from improper installation or shifting of the foundation, which can cause pipes to rupture and break.
  • Piping has reached is lifespan.

One of the causes of slab leaks is the friction caused by your home’s water pipes rubbing against your concrete slab or other piping below the slab. This friction can cause areas of a pipe to weaken, resulting in small or large leaks. It is also possible the entire pipe could rupture if damage is significant.

Know the Signs

Early detection of slab leaks is important to preventing water and structural damage in your home. And it can be difficult to detect slab leaks without the use of a professional’s high-tech equipment. But there are some telltale signs to watch out for that could indicate that your home might have one or more slab leaks:

  • Water damage seeping up from the floor
  • Cracks in your cement floor
  • Unexplained hot spots in the floors around your home
  • A sudden and unexplained rise in your water bill
  • Warped hardwood flooring or damp carpets
  • Your hot water heater constantly runs when you are not using hot water
  • Puddles of water around the inside of your home
  • Decreased water pressure
  • Seeing or smelling mold or mildew

If your home has any of these signs of a slab leak, chances are some damage has already been done. But you can prevent further damage by having a professional plumber test your slab for leaks, locate the leak and repair it promptly.
