Slab Leaks: Could it be a Water Slab Leak? How to Tell and What Action to Take

A slab leak is a leak in the water pipes under your home – specifically, under the foundation or concrete slab that your home is built upon.

Such a leak can cause damage to your home by flooding your home with water and destroying your flooring and causing damage to your sheetrock and paint. It can also lead to an increase in your water bill usage and charges, and your utility bill depending if you have a Gas/Electric Water Heater and your Slab leak is a hot water leak, which we estimate 80% of the slab leaks tend to be Hot Water Leaks rather than a cold water leak.

Your best solution is to get the leak fixed by a professional licensed plumbing company that specializes in water leak detection as soon as possible. But how do you know if you have a slab leak, and what causes it?

Common Signs That You Might Have a Slab Leak

How can you tell if your pipes are leaking under your slab foundation? Here are just a few of the signs you might have a slab leak.

  • Your Floor Is Hot: If the leak is in your hot water pipes, your floor will feel warm. The water has leaked into and under the concrete slab, and now it’s warming the floor. This may also make your water heater run constantly.You Hear Water Sounds: When you hear water sounds or water rushing or a humming sound near a fixture such as a bathroom sink or kitchen sink or water heater. This is a good sign you have a slab leak. The sound is water replenishing the pipes due to loss under slab.
  • High Water Bills: Even a few dollars’ difference can indicate something is wrong with your pipes. Pay close attention to your bill. If it goes up exponentially one month or steadily over a few and you aren’t doing anything out of the ordinary, there’s a good possibility that you have a leak.
  • Your Carpet or Flooring is Damp: Wet floors are an obvious indicator that you have some sort of leak. The water that’s leaking out of your pipes has nowhere to go after a while. Once it starts accumulating, the pool of water will eventually lead to wet flooring.
  • Your Water Pressure Is Low: If water is leaking out of your pipes, there’s less water available for your indoor plumbing needs. Pay attention to the water pressure when you take a shower or wash your hands. Unexpected low water pressure can be a sign there’s a leak.

Understanding Slab Leaks: Causes and Contributing Factors

Slab leaks occur when the water pipes installed beneath the concrete foundation of a home develop leaks. These pipes run under various parts of the house, including kitchens, bathrooms, and garages, and connect to the home’s plumbing system. When a leak happens beneath this concrete slab, it’s termed a slab leak.

Common Causes of Slab Leaks

Aging Pipes The age of your pipes plays a significant role in the likelihood of developing a slab leak. Over time, pipes can corrode and wear out, particularly in older homes that often feature softer copper pipes. This gradual deterioration can lead to leaks.

Abrasion Pipes are subjected to continuous movement due to the expansion and contraction from temperature changes in the water. This movement can cause the pipes to rub against the concrete or any rocks they come into contact with beneath the slab. Over time, these small abrasions can result in leaks. Seasonal changes, such as the transition from summer to winter or fluctuations between rainy and dry periods, can exacerbate this issue by causing additional pipe movement.

Installation Issues Improper installation can also be a cause of slab leaks. If copper piping was excessively bent or damaged by tools like shovels during the initial construction phase, this can create weak points in the system. These vulnerabilities may eventually lead to leaks.

Poor Water Quality The quality of your water can significantly affect your pipes. Ideally, the pH level of your water should be between 6.5 and 8.5. Water that is too acidic or too alkaline can accelerate the corrosion process, compromising the integrity of your pipes and increasing the risk of slab leaks.

Understanding these causes can help in taking preventive measures to protect your home from the costly and damaging effects of slab leaks. Regular maintenance and monitoring can go a long way in ensuring the longevity of your plumbing system.
