Understanding the Causes of Slab Leaks and How to Prevent Them

June 28, 2023

Slab leaks are a common and potentially costly plumbing issue that occurs when water pipes beneath the concrete foundation of a building develop leaks. Detecting and repairing slab leaks promptly is crucial to prevent structural damage and water wastage. The professional team at City Plumbing and Rooter can help you understand the common causes of slab leaks to take steps that will minimize your chance of suffering from a slab leak.

How Shifting Soil and Ground Movement Cause Slab Leaks

One of the primary causes of slab leaks is shifting soil and ground movement. This can happen due to various factors, including earthquakes, soil erosion, or changes in the water table. As the ground shifts, it puts pressure on the water pipes, leading to cracks and leaks. To prevent slab leaks related to ground movement:

  • Ensure proper drainage around your property to prevent excessive water accumulation.
  • Regularly inspect and maintain the foundation of your building.
  • Consult with a professional to assess and address any soil stability issues

The Dangers of Corrosion and Aging Pipes

Over time, pipes can deteriorate and develop leaks due to corrosion or natural aging. Factors like water quality, pipe material, and maintenance practices can contribute to this issue. To prevent slab leaks caused by corrosion and aging pipes:

  • Have your plumbing system inspected regularly by a professional plumber.
  • Consider repiping with modern, corrosion-resistant materials if your pipes are old or showing signs of deterioration.
  • Monitor water quality and address any issues that could accelerate pipe corrosion

High Water Pressure and Slab Leaks

Excessively high water pressure can put a strain on your plumbing system, including the pipes beneath your foundation. The increased pressure can lead to leaks and even cause pipes to burst. To prevent slab leaks due to high water pressure:

  • Install a pressure regulator to control and maintain the water pressure within a safe range.
  • Regularly test your water pressure and adjust the regulator if necessary.
  • Consult with a plumber to assess your plumbing system's capacity and make any required adjustments.

Improper Installation or Construction Damage Problems

Slab leaks can also result from poor installation practices or damage sustained during construction. Common causes include improperly soldered joints, accidental pipe punctures, or excessive stress on pipes during the building process. To prevent slab leaks caused by installation errors or construction damage:

  • Hire licensed and experienced plumbers for all plumbing installations and repairs.
  • Conduct thorough inspections during construction to identify and address any potential issues promptly.
  • Implement quality control measures to ensure proper pipe installation and protection.
