Slab Leaks: What They Are & When To Address Them


post img

Several important aspects of your plumbing system lie beneath your home, in its slab foundation. These pipes connect your home’s faucets and drain to your city’s water supply line and sewage system.

As your house ages, the pipes in your slab can become damaged and leak. Detecting a slab leak, however, can be difficult.

What Is a Slab Leak?

Slab leaks are caused when the copper pipes in your home’s concrete slab become corroded or damaged. The compromised pipes then pump water up through your home’s foundation or near its exterior.

Whether small or large, these leaks can remain hidden for a while, wreaking havoc on your home’s foundation and plumbing system in the meantime.

Signs You May Have a Slab Leak

Because these leaks are beneath your home, it can be difficult to identify them quickly. Below are common signs you have a leak in your foundation that needs to be repaired:

  • Pooling water
  • Unexplained increase in water bills
  • Running water sounds when there are no taps open in the home
  • Visible cracking in your foundation
  • Stained or damp flooring or carpet
  • Weak water pressure
  • Odors coming from floors or walls
  • Visible alteration in soil around home
  • Uneven growth in lawn or plants near the home’s foundation
  • Mold or mildew growth

What Causes Slab Leaks?

There are multiple potential causes of this kind of leak:

  • Ineffective or improper installation
  • Earthquakes
  • Extremely acidic water
  • Deterioration of copper pipes over time
  • Excessive water pressure
  • Soil shifting beneath your foundation

When Should You Repair Slab Leaks?

It’s important to address slab leaks as soon as they’re discovered, as they can cause serious and irreparable damage to your home. They’ve also likely been costing you big in your monthly water bill as water has been essentially running constantly since the leak started.
