Now that you understand what causes slab leaks let's take a look at some of the most common signs that you may have one in your home.
1. High Water Bills
One of the most obvious signs of a slab leak is a sudden increase in your water bill. If you haven't changed your water usage habits, but your bill has significantly increased, it could be a sign that you have a leak somewhere in your home.
2. Low Water Pressure
A slab leak can cause a decrease in water pressure throughout your home. If you notice that your faucets and showerheads are not producing as much water as they used to, it could be due to a leak in your slab.
3. Wet Spots on the Floor
If you have carpet or hardwood flooring, you may notice wet spots or discoloration on the floor. This is a clear sign that water is leaking from somewhere, and if it's coming from under the floor, it could be a slab leak.
4. Mold Growth
Mold thrives in damp, dark environments, making a slab leak the perfect breeding ground. If you notice mold growth in your home, particularly near the baseboards or on the walls, it could be a sign of a slab leak.
5. Cracks in the Walls or Foundation
As the soil shifts due to a slab leak, it can cause cracks to form in your walls or foundation. These cracks may be small at first, but they can quickly grow and become a significant issue if not addressed.
6. Hot Spots on the Floor
If the leak is coming from a hot water pipe, you may notice hot spots on your floor. This is because the hot water is heating up the concrete slab, causing it to feel warm to the touch.
7. Sound of Running Water
If you hear the sound of running water when all of your faucets and appliances are turned off, it could be a sign of a slab leak. The sound may be faint, but if you listen closely, you may be able to hear it.
8. Foul Odors
A slab leak can cause stagnant water to accumulate under your home, leading to a musty, foul odor. If you notice a strange smell in your home, it's worth investigating to see if it could be caused by a slab leak.
