How Do You Know If You Have a Slab Leak? 7 Warning Signs
How Do You Know If You Have a Slab Leak? 7 Warning Signs

A water leak is usually easy to notice when it happens under a sink or around a toilet. But what happens when the leaking pipe is underneath your home?


A slab leak occurs when a water line beneath a home's concrete foundation begins leaking. Because the plumbing is hidden beneath the slab, the problem can develop without an obvious puddle or visible broken pipe.


Fortunately, your home may give you clues that something isn't right.


If you own a home in Riverside, here are seven warning signs of a slab leak you shouldn't ignore.


1. Your Water Bill Suddenly Goes Up

An unexplained increase in your water bill can be one of the first indications of a hidden plumbing leak.


If your household's water usage hasn't changed but your bill continues to climb, water may be escaping somewhere within the plumbing system.


A slab leak can continuously waste water beneath your home, even when you're not actively using a faucet, shower or appliance.


If you can't find an obvious source for the increase, professional leak detection can help determine whether a hidden plumbing leak is responsible.


2. You Notice Warm Spots on the Floor

Does one area of your floor suddenly feel warmer than the surrounding area?

If the leaking pipe beneath the slab carries hot water, escaping water may cause the flooring above it to feel unusually warm.


You may notice this while walking barefoot across tile, hardwood or another hard flooring surface.


A warm floor doesn't automatically mean you have a slab leak, but a new or unexplained hot spot is worth investigating, especially if you're noticing other plumbing symptoms at the same time.


3. You Hear Running Water When Everything Is Turned Off

Your home should generally be quiet when no one is using water.


If you hear running, dripping or hissing water even though the faucets, showers, toilets and water-using appliances are off, there could be a hidden leak somewhere in your plumbing system.


When you can't locate the sound's source, the water could be moving somewhere you can't see, including underneath the slab.


4. Your Floors Are Damp or Wet

Moisture appearing on flooring without an obvious source deserves attention.


Depending on the location and severity of the leak, you may notice:

  • Damp carpeting

  • Discolored flooring

  • Warped or damaged flooring

  • Moisture along baseboards

  • Unexplained wet areas


Don't assume unexplained moisture is simply from humidity or a spill. Finding the source early can help limit additional water damage.


5. Your Water Pressure Has Dropped

A significant plumbing leak can affect the amount of water reaching your fixtures.

You might notice that showers aren't as powerful as they used to be or that several faucets have lower pressure.


Low water pressure can have many possible causes, so it doesn't necessarily mean you have a slab leak. However, if the pressure change happens suddenly or appears alongside higher water bills, wet flooring or other warning signs, a hidden leak should be considered.

6. You Notice Musty Odors or Signs of Moisture

Water trapped underneath flooring or around building materials can create damp conditions and unpleasant odors.


You may notice a musty or mildew-like smell even though you can't see where the moisture is coming from.


Rather than simply trying to cover up the odor, it's important to determine whether a hidden plumbing leak is creating excess moisture.


7. Your Water Meter Moves When You're Not Using Water

Your water meter can sometimes provide another clue that water is escaping somewhere in the plumbing system.


Turn off faucets, appliances and other water-using fixtures in the home. If the meter continues registering water use, there may be a leak somewhere in the system.


A meter test won't tell you where the leak is located, but it can provide another reason to have the plumbing inspected.


Is It Definitely a Slab Leak?

Not necessarily.


Many slab leak warning signs can also be caused by other plumbing problems. For example, a high water bill could come from a running toilet, leaking irrigation line or dripping fixture. Low water pressure can have several possible causes as well.


That's why finding the source of the problem is important before deciding what needs to be repaired.


Professional leak detection can help determine whether you're dealing with a slab leak, leaking pipe or another plumbing problem.


How Are Slab Leaks Detected?

Because the affected plumbing is underneath the home's foundation, locating a slab leak doesn't necessarily mean immediately opening the concrete.


First Place Plumbing Solutions uses leak-detection methods designed to help pinpoint hidden leaks and determine where the problem is located. Once the source is identified, the plumber can recommend an appropriate repair method. Their existing slab-leak service includes options such as targeted repair, pipe rerouting and repiping depending on the situation.


What Should You Do If You Suspect a Slab Leak?

Don't ignore the warning signs simply because you can't see the leak.


Pay attention to changes in your water bill, water pressure, flooring and plumbing sounds. If several warning signs appear together or you have reason to believe water is leaking beneath your home, schedule an inspection.


The sooner you identify where the water is coming from, the sooner you can determine what type of repair is needed.
