How can you tell if you have a slab leak?
These are the 5 most notable symptoms of a water leak in or around your slab:
- A noticeable increase in your water bill
- Water meter moves after water is turned off
- The sound of running water when no taps are on
- Warm or cold spots on your flooring
- Low water pressure
How common are slab leaks?
It depends where you live. In most parts of America, slab leaks occur about once every 30 years. Dallas homes average one slab leak roughly every 15 years.
How do you locate a water leak under your slab?
The 2 best ways to locate a water leak under your concrete slab are acoustic leak detection and video camera inspection.
Acoustic detection uses sound to identify leak location. A camera inspection is needed if hydrostatic testing fails, or if acoustic detection is inconclusive.
How long does it take to fix a slab leak?
Most simple slab leaks are fixed in 2-3 days. If your specific leak requires pulling a city permit, add an extra day to your project timeline.
If you’re rerouting your pipe, plan an extra day for drywall repairs. (Note: Drywall repairs are not included in the cost of plumbing work.)
Are slab leaks covered by homeowner’s insurance?
Homeowner's insurance companies don't love to cover leaks in or near your home's foundation. If you want your slab leak repair covered, you need to follow a precise set of steps to improve your odds of coverage.
Follow these 4 steps in order to increase the chances your slab leak is covered by insurance:
- Immediately contact your insurance provider in the event of a freshwater leak.
- Hire a master plumber for 2 key tests: water pressure testing and hydrostatic testing.
- Consult a structural engineer before and after plumbing repairs.
- File all necessary paperwork to your homeowner’s insurance.
What is the top warning sign of a slab leak?
If your water meter moves after you turn off the water supply, you likely have a slab leak. Other notable symptoms include an increase in your water bill, warm or cold spots in your flooring, and the sound of running water with no taps on.
Can I DIY slab leak repair?
No, you cannot DIY slab leak repair. Leak location requires precise thermal imaging, and attempting DIY slab repairs may void your insurance.
Why is there a warm spot on my floor?
A warm spot on your floor usually indicates a hot water line leak near your foundation. This is most prevalent in homes with concrete slab foundations. Schedule a hydrostatic test with your plumber to identify the leak's location.
What if my slab leak is in an inaccessible location?
For pipe leaks and damage that's extremely hard to reach (i.e. under your slab), pipe rerouting is the best alternative. Your plumber establishes a unique path for your new sewer line, then disconnects the damaged pipe section and seals it at both ends to prevent further leaks.
