What Causes a Slab Leak?

There are many ways a home can be affected by water damage. One of the most causes is slab leaks. A slab leak is a leak that has developed in the copper water lines running below the concrete foundation of your property. Now let's talk about what can cause these leaks.

• Improper Construction: This can be the most common cause of slab leaks which is improperly installed or poor-quality pipes. 
• Outside Pressure: Pressure on the pipes can come from the property slightly moving due to an earthquake or soil erosion.
• Poor Water Quality: Keep an eye on your water's pH level. Water that is considered hard or acidic can corrode pipes. You can identify the water quality by looking for blue or green stains which would identify water as neutral.
• Abrasion: This is also another common reason for slab leaks. During regular use, the pipes rub against concrete, gravel, other materials, or other nearby pipes. The constant friction can cause them to gradually wear down and cause leaks. Mainly happens with hot water pipes because they expand as they heat up.
• Time: Older homes have a higher risk as they have had extended periods of pressure on pipes. Sometimes slab leaks in older homes require new pipes rather than repairing them. It is important to keep an eye out for irregularities to help prevent slab leaks as well.
