A slab leak is one of the most frustrating plumbing issues homeowners in the Dallas area can face. Because the pipes are buried beneath the concrete foundation, leaks aren’t always easy to spot. Left unchecked, a slab leak can cause costly damage to your home’s foundation, flooring, and plumbing system. The good news is that there are signs you can look for to catch the problem early and steps you can take to check if your home has a hot water slab leak. In this blog, our experts at Legacy Plumbing cover what you need to know about slab leaks and how to check for them without needing any tools.
What Is a Slab Leak?
In many North Texas homes, water lines run underneath the concrete slab foundation. Over time, these pipes can develop leaks due to soil shifting, corrosion, or even the natural settling of your home. When the leak happens on the hot water side of your plumbing system, it’s known as a hot water slab leak.
Signs of a Hot Water Slab Leak
Here are some common indicators that you may have a problem:
- Unexplained warm spots on the floor: If you notice certain areas of your floor feel warm, it may be hot water escaping beneath the slab.
- Spike in water bills: A hidden leak can cause your water usage to spike, even if your daily habits haven’t changed.
- Running water sounds: If you hear water running when no fixtures are in use, it could be leaking under your home.
- Moisture or mildew: Slab leaks can lead to damp carpet, warped wood flooring, or musty odors.
How To Check for a Hot Water Slab Leak Yourself
If you’ve noticed any signs of a possible slab leak, this test can help you confirm if you are actually dealing with a hot water slab leak. While a professional plumber should confirm and repair the problem, you can try this method to check first. This test requires no tools, just a working shut-off valve on your water heater.
To check for a slab leak, follow these steps:
- Turn off all fixtures: Check all of your sink, shower, and tub faucets to make sure they are fully turned off and not leaking. Any fixture that receives hot water needs to be shut off and not leaking for this test to work.
- Unplug the recirculation pump: Go to your water heater and check to see if there is a recirculation pump. If there is, go ahead and unplug it.
- Turn off the cold water: Turn off the cold water supply valve on your water heater. It should be to the top right of the water heater when you are facing it.
- Wait: Wait for about two minutes.
- Turn the cold water on: After waiting, quickly turn the valve back on. If you hear or feel water rushing through the valve as you turn it on, you likely have a slab leak. If there is no sound, then you probably do not.
If the test is inconclusive, you can try it again, making sure to wait longer than two minutes before turning the cold water supply valve back on. Another test you can perform is feeling for hot spots on your floor, as this is one of the most common indicators of a hot water slab leak.
Why You Shouldn’t Wait to Call a Professional
