4 Signs You’ve Got a Slab Leak

A slab leak is a term that refers to a leak from a pipe that is located underneath the concrete flooring or subfloor in your home. Slab leaks can occur for a number of reasons, including a pipe cracking or bursting. Knowing what the signs are of a slab leak can help you determine whether you may have a potential leak. Here are four common signs associated with a slab leak. 

Warm or Cold Spots on the Floor

One of the signs that you may have a potential slab leak is warm or cold spots on the floor. This is more noticeable if you have a concrete floor or tile floor compared to those that have carpet over their slabs. When there is a leak, moisture is present underneath your slab. If you have a cold water leak, this moisture can make the cement cold, while warm water will make the cement warm. This is why you may feel warm or cold spots on the floor. 

The Sound of Rushing Water

Another sign that you may have a slab leak is the sound of rushing water. If you have a pipe that is damaged, the water may not be flowing through the pipe. Instead, it may be gushing out of the pipe. If the leak is large, you may sometimes hear the sound of rushing water. If you hear water while you are sitting in a room in your home, but you cannot figure out where the sound is coming from, put your ear to the floor. If the sound gets louder, you may have a slab leak. 

Higher-than-Normal Water Bills

The third sign of a slab leak is a higher-than-normal water bill. If your water bill has suddenly and unexpectedly grown in size, you may have a leak somewhere in your home. A plumbing leak detection company should be called in to find out where the leak is located.

A Puddle of Water

The final sign of a slab leak is a puddle of water. If a slab leak goes undetected for some time, water may build up until you start to see water puddling or pooling on your floor. If your flooring starts to feel wet or damp, and/or you see a puddle of water in a room, you likely have a slab leak. 

If you suspect you have a slab leak, it is important to bring in a plumber quickly. A plumber can perform plumbing leak detection on the slab and determine whether a leak is present and where the leak is located. Once they have located the leak, they will have to jackhammer out the area of the slab over the damaged pipe and repair the pipe. This can be a big process, but failing to repair a leak in a timely manner can lead to larger issues, such as water damage and mold growth.
