What Are Slab Leaks? How Do I Know My House Has One?

slab-leak-crack-in-foundationThere are many types of leaks that can affect the plumbing in a home. In some situations, they’re immediately visible and therefore can be repaired fast with a call to a plumber in Fontana, CA. Then there are the insidious hidden leaks behind walls that may escape detection for months before they begin showing signs they’re creating damage.

And then there are slab leaks—the most difficult type to detect and repair. We’ll help you better understand slab leaks and how to find them. You can trust our plumbers to come to your rescue to fix the problem.

Slab Leaks—The “Under Stone” Leak Problem

The simple definition of a slab leak is that it’s any leak in a pipe down in the concrete foundation of a home. Technically, any leaking pipe down in rock, stone, or hardscape is considered a slab leak, but as a homeowner, you’ll only need to worry about a slab leak in the foundation.

Slab leaks can occur in either hot or cold water pipes. Because hot water pipes move around more (they expand with the heat), they are more likely to abrade against the slab and leak. Around 80% of slab leaks occur in the hot water lines. The leaks can also occur because of ground shifting (a major problem we have in California because of quakes) and corrosion due to chemicals found in the water.

Discovering You Have a Slab Leak

A leak down inside concrete sounds like it’s almost impossible to notice. But these leaks do create a number of signs you can watch for:

  • High water bills: Few types of leaks in a home create more water waste than slab leaks. When you see that your water usage has significantly climbed for no discernable reason, it’s a good idea to call in a plumber to find out if slab leaks (or leaks anywhere in the house) are responsible.
  • Odd water heater behavior: Does your tank water heater turn on and off at times when nobody is using hot water? Because most slab leaks occur in hot water lines, this behavior from the water heater might be sending a warning. (Regardless of the cause, you’ll want the water heater looked at.)
  • Cracks: When you see cracks along the concrete around your house, it might be pressure from the slab leaks.
  • Warm floors: Hey, warm floors are nice in the morning, right? But this shouldn’t be happening at all—it can mean water escaping from a slab leak and into your subfloor.
  • Humidity: A rise in humidity around your home that doesn’t match the weather? Another indication of slab leaks.
