A sudden spike in your monthly water bill, a warm spot underfoot, or a musty smell may not raise concerns at first. This is particularly true if the source is a small kitchen or toilet leak that you can fix. However, hidden slab leaks can go undetected for a long time, causing significant damage and costly repairs. If you are sure whether you are dealing with a slab leak or high water pressure, Mr. Rooter Plumbing can help. We understand that both problems can feel the same initially, and can accurately diagnose the root cause.

Is It a Slab Leak or High Water Pressure? What Your Plumbing Is Trying to Tell You

What Is the Difference Between a Slab Leak and High Water Pressure?

A slab leak is a damaged line beneath your concrete foundation, allowing water to escape into the surrounding. With that said, identifying hidden plumbing damage can be difficult if you don’t have the proper tools and experience required. Plumbing service providers use specialized acoustic listening devices and thermal imaging cameras to pinpoint the source, assess the damage, and determine the best course of action.

On the other hand, high water pressure refers to the increased force of water from your faucets. While a sudden increase in water pressure is ideal in the shower, kitchen, or when irrigating your yard, it can pose risks to your plumbing infrastructure. If your home’s water pressure exceeds safe levels, it can strain older pipes, connections, and fixtures.

If you detect signs of a hidden slab leak or excess water pressure from plumbing fixtures, call a plumber in Chattanooga, TN quickly to fix the root cause. Professional technicians understand the complexities of different systems and accurately diagnose issues before they escalate into bigger, more expensive problems.

Why Slab Leaks Are Common Plumbing Problems?

Slab leaks are a real concern for residential and commercial properties. With that said, the local ground and infrastructure style can contribute to slab leaks. The most common reasons for underground leaks include soil shrinking and expansion due to moisture, sudden earth shifts, slab foundation, and aging pipes.

In areas that have clay soil, it can be the biggest culprit. Clay soil traps moisture and expands, but it significantly shrinks when dry. This constant movement throughout the seasons strains underground lines, making them more susceptible to damage. Furthermore, decades-old plumbing coupled with shifting soil can take a toll on your system and wreak havoc. That’s why it’s important to consult a plumbing service provider if you suspect a hidden leak for immediate attention.

How Do Plumbers Detect Slab Leaks?

While a standard leak is easy to detect through a visual inspection of your layout, a slab leak requires professional-grade tools and extensive expertise. The most popular leak detection techniques plumbing technicians use include water meter tests, acoustic listening, thermal imaging, pressure tests, and video camera inspection. As a DIY enthusiast, attempting these methods without the proper expertise or equipment can exacerbate underlying issues.

Additionally, plumbing service providers can link the findings from these methods with small signs that may go undetected to the untrained eye. This commitment to precision and attention to detail provides peace of mind, knowing your plumbing system is in capable hands.

At Mr. Rooter Plumbing, we believe that residential and commercial systems are different, and each has something to say if you are willing to listen. By familiarizing yourself with the warning signs of a hidden leak or pressure-related problems, you can act quickly before things get out of hand. Contact us today to schedule a consultation with our experts and enjoy a plumbing system that performs reliably and efficiently for years to come.
