The Floor in My Laundry Room is Hot and I Suspect a Slab Leak: What Are My Options?
KP Plumbing in Diamond Bar, California
Homeowners rarely expect to encounter a warm floor in their laundry room, bathroom, or kitchen, but when it happens, it can be a cause for concern. A hot spot on your floor often points to an issue beneath the surface, most commonly a slab leak. Slab leaks occur when a water line underneath the concrete foundation of your home springs a leak. If you’re dealing with a warm or hot floor in any floor of your house, it’s crucial to understand the potential causes and your options for fixing the problem.
At KP Plumbing, we’ve helped many homeowners in Diamond Bar detect and repair slab leaks. If you’re concerned about a hot floor in your laundry room, this blog post will help you understand why it’s happening, the risks involved, and your options for repair.
What Causes a Slab Leak?
Before we dive into your options, let’s quickly examine why slab leaks happen. The pipes running through the concrete slab of your home can develop leaks for a few reasons:
- Pipe Corrosion: Over time, water pipes may corrode, especially if the water has a high mineral content or if the pipes are old.
- Shifting Foundation: Any movement or shifting of your home’s foundation can put stress on the pipes, causing them to crack or rupture.
- Poor Installation: Pipes that were not installed correctly during the initial construction of your home are more prone to leaks. Poorly fitted joints or low-quality materials can be at fault.
- Water Pressure: Excessive water pressure can cause strain on pipes, leading to a slab leak over time.
Slab leaks are not something to ignore. They can lead to costly repairs, damage to your home’s foundation, and mold growth. It’s important to take action when you notice a warm floor, especially in areas where hot water pipes are often present.
How to Confirm a Slab Leak
First, let’s talk about how to confirm that you’re actually dealing with a slab leak. Here are a few steps you can take to determine whether or not a leak is present:
- Check Your Water Bill: If your water bill has skyrocketed without an increase in usage, this could be a sign of a hidden leak.
- Listen for Running Water: If you hear the sound of water running even when all appliances and faucets are turned off, there might be a leak.
- Monitor the Floor’s Temperature: A hot spot in the floor strongly indicates a leak in a hot water line beneath the slab. Use an infrared thermometer to check the temperature difference between the floor in the laundry room and other areas.
- Inspect for Water Damage: Look for signs of water damage, such as damp spots, cracks in the walls or flooring, or a musty odor. Mold growth can also indicate an ongoing leak.
- Check the Meter at the Main Water Shut Off: If the meter is running and no one is using water in the house, you know you have a leak. To check if it is the hot water line that is leaking, turn off the hot water at the shut-off valve above the water heater, if you have one. Then go back to the main box and check again to see if the meter at the main box has stopped. If it has stopped, you know you have a leak in the hot water line. If not then you can assume it’s the cold water line.
- Call a Professional: Finally, it’s always a good idea to bring in a professional plumber. At KP Plumbing, we have specialized tools such as leak detection devices, infrared cameras, and acoustic listening devices that can pinpoint the exact location of the leak.

Risks of Ignoring a Slab Leak
Slab leaks are more than just an inconvenience. They can cause serious damage to your home if left untreated. Some of the risks of ignoring a slab leak include:
- Foundation Damage: A slab leak can erode the soil beneath your home’s foundation, leading to cracks and structural issues.
- Water Damage: The continuous flow of water can cause extensive damage to your flooring, walls, and other parts of your home.
- Mold Growth: Moisture buildup from a slab leak creates the perfect environment for mold to grow. Mold can not only damage your home but also pose serious health risks.
- High Water Bills: Leaking water adds up quickly, and you could find yourself paying for hundreds of gallons of water that you never used. Check your water usage on your bill to see if your water consumption has increased. Walnut Valley Water District Website.
What Are Your Options for Repair?
So, you’ve confirmed a slab leak. What are your options for repair? Luckily, you have several choices, depending on the severity of the leak, the condition of your plumbing, and your budget. Here are the most common solutions:
1. Spot Repair
The spot repair method involves accessing the leak directly by cutting into the slab at the leak’s location. Once the plumber reaches the pipe, they repair or replace the damaged section. This option works best when the leak is confined to a small area. It is also the least invasive option. However, if the pipes are old or in poor condition, a spot repair might only be a temporary fix. At KP, this is not our first choice.
2. Pipe Rerouting
Another option is to reroute the plumbing entirely. Instead of breaking through the slab, a plumber can abandon the leaking section of pipe and install new piping above ground. Pipe rerouting is often a good choice for homes with multiple slab leaks or when the plumbing system is aging. It prevents future leaks from occurring under the slab but involves installing new pipes along walls, ceilings, or other parts of the home.
3. Epoxy Pipe Coating
For leaks in smaller sections of the pipe, epoxy pipe coating can be a non-invasive solution. This method involves applying a layer of epoxy inside the pipe, sealing the leak from within. The plumber inserts the epoxy through the pipe, allowing it to harden and create a durable seal. This option is less invasive and can work well in cases where there are minor leaks or cracks.
Suspect a slab leak? A PEX bypass may be the answer
4. Pex Pipe Solution
Sometimes, you can insert a PEX pipe through the old copper line. This accomplishes the bypass that is needed. However, if the old soft copper has 1/2 inch dimension you may lose some of the water pressure you had before. Because you will have to choose a PEX pipe with a smaller diameter. Repipe with PEX.
5. Repipe the Entire Home
If your home has older plumbing, or if you’ve experienced multiple slab leaks, you might want to consider repiping the entire home. Repiping involves replacing all the pipes, not just the ones under the slab. While this option is more costly upfront, it can save you from ongoing leaks and costly repairs in the future.

Preventing Future Slab Leaks
Once the leak is repaired, you’ll want to prevent future problems. Here are a few preventative measures:
- Regular Plumbing Inspections: Schedule annual plumbing inspections to catch potential issues before they become serious problems.
- Monitor Water Pressure: Install a pressure regulator to maintain a safe water pressure level and avoid putting stress on your pipes.
- Use Quality Materials: When replacing pipes or installing new ones, always opt for high-quality materials that can withstand wear and tear.
