Any breach in your plumbing system is a cause for concern, and obviously, should be taken care of as soon as possible. However, not all leaks present themselves in the same ways, and sometimes, it can be pretty tricky to tell what’s what.

Slab leaks, in particular, can be tricky to spot. Not only that, but they are a HUGE deal! Why? Because they can cause all sorts of damage to your home and property! Below, we’ll explain more about what a slab leak is and how to tell if you might have one. Keep reading to find out more!

What is a Slab Leak?

Slab leaks are leaks in the pipes located below the foundation or concrete slab of your home. These leaks typically require immediate service because they can cause structural damage and cracks in your foundation. Depending on the type of pipe, they can also cut off your freshwater supply or cause raw sewage leaking on your property if a sewer line breaks.

Older homes are more likely to encounter these types of leaks, but newer homes are not immune. It is best that all homeowners be aware of the warning signs.

How To Tell if You’ve Got One

Like we mentioned above, there are a number of signs that suggest you’ve got a slab leak, including:

A drop in water pressure

When water escapes from your plumbing system, you can expect decreased water pressure throughout the home. A leak will cause low water pressure in all of your faucets, not just one.


Water pooling inside your home is never a good sign. Slab leaks cause water to come up from underneath the floor. This typically occurs in the basement, if you have one. Otherwise, you might notice this happening on your first floor.

A slab leak can also cause water to pool around the foundation outside of your home. If your yard is noticeably wetter, call a plumber to pinpoint the source of your leak.

Cracks in the foundation

Due to their location, slab leaks can lead to cracks in the foundation. The water escaping from these leaks puts an enormous amount of pressure on the building materials, leading to cracks. Even if you don’t see water yet, foundational cracks are a clear sign that you need to contact a plumber right away.

Costly bills

In general, any leak in your plumbing system is going to cause a spike in water costs. A slab leak can waste an extraordinary amount of water, whether or not your faucets are running. Pay close attention to what you are paying, and contact a professional right away if you find yourself paying more than you ever had for water.
