One of the most critical plumbing issues that a homeowner can face in San Diego is the slab leak. These are water line leaks found beneath your home's foundation. If these go unchecked, you will find a significant amount of structural damage done to your house. In cases where you find high water bills, damp flooring, or a sudden unexplained drop in water pressure, it may be necessary to repair slab leaks in San Diego.





Knowing Slab Leaks


This refers to the slab leak where leaks develop due to several factors, in pipes under the concrete slab foundation of a house. After some time, this leak would accumulate moisture leading to the weakening of the slab foundation, making costly repairs.



Causes of Slab Leaks

Many things contribute to slab leaks on San Diego houses, and include;


1. Pipe Corrosion


San Diego's water quality sometimes leads to corrosion of copper pipes. When water acts on metal pipes, pinhole leaks are produced, which are the causes of slab leaks.


2. Inadequate Installation


If, during construction, the plumbing system was not well installed, the pipes may change position or get weak points; hence, leakages under the slab occur.


3. Wear from Soil Shift


Earthquakes or ground shifting cause pipes to rub against rough surfaces and thus may result in leakage after a period.


4. Water Pressure


Too much pressure of water strains your pipes and creates a potential chance for cracks and leakage below your house's foundation.


5. Chemical Reactions in Water


At times, the water in San Diego may react chemically and increase the speed at which the pipes wear out and result in leakage.


Slab Leak Detection in San Diego: Signs That One Is Needed


Getting a slab leak detection done as early as possible saves thousands of dollars on repairs. These are some of the warning signs:


1. Unexplained Spike in Water Bills


If the water bill has skyrocketed without an increase in usage, consider such amounts a sign for an unknown leak lurking under your home.


2. Damp or Warm Spots on Flooring


Hot spots on the floor can be created by a leaking pipe bearing hot water.


3. Low Water Pressure


Reduced Water pressure could be one of the signs of slab leak: the water is not reaching your faucets, rather it is leaking somewhere under the slab.


4. Growth of Mold and Mildew


Extra moisture from the slab leak would normally provide favorable conditions for mold and mildew growth and subsequently contaminate indoor air.


5. Cracks in Walls or Flooring


Water accumulation under the foundation can shift the structure and thereby develop cracks in the flooring and walls.


How Professionals Find Slab Leaks


Professional plumbers employ advanced technology to locate slab leaks without digging. Some of the common methods include:


1. Electronic Leak Detection


This involves using specialized equipment to listen for the sound of escaping water to help identify leak locations.


2. Infrared Thermography


Thermal imaging cameras are employed to detect temperature differences in your flooring, indicating possible hidden leaks.


3. Pressure Testing


The pressure inside various sections of the plumbing system is checked to find out whether there is a leak beneath the slab.


4. Camera Inspections


A small camera is inserted into the pipes for visual inspections to ascertain the condition of the plumbing system for any leaks.


Slab Leak Repair in San Diego: Available Remedies


Once a slab leak is detected, several options for repair may be undertaken by the professionals, depending on the severity of the problem.


1. Spot Repair


This is a localized repair where access to the pipe is made through the slab, and the damaged section is repaired.


2. Rerouting the Pipes


If there are multiple leaks, rerouting water lines above ground can be a long-term solution to prevent future slab leaks.


3. Epoxy Pipe Coating


When fluids leak through the pipes, epoxy lining is applied on the inside to seal them without costly excavation.


4. Pipe Repiping


If pipes are corroded beyond repairs, whole house repiping may be done with better materials like PEX or copper.
