Top Causes of Slab Leaks

Schedule Online

A concrete slab leak occurs when the pipes beneath or inside your property’s foundation start to leak. Although these leaks might seem insignificant, they can result in considerable water damage and extensive repairs. When left ignored, the leaks can soak the soil beneath your home and make floors uneven. Worse, they can eventually make your house sink into the ground.

It’s essential to know the top causes of slab leaks so you can protect your home from such a disaster. Experts at Zippity Split Plumbing outline these causes.

Improper Construction

Improper installation and poor-quality pipes are the leading cause of slab leaks. If your pipes get dented, kinked, or bent during the installation process, the affected areas can burst or leak due to the abrasive effects of consistent water flow. Copper pipes, specifically, are at a higher risk of corrosion as they are typically softer and more susceptible to the elements. In some instances, particularly in old homes, slab leaks might necessitate pipe replacement instead of a slab leak repair in Scottsdale, AZ.

Outside Pressure

Excessive water pressure isn’t the only pressure that can result in slab leaks. If the soil beneath your home slightly moves, it can make your house slightly shift, exerting too much pressure on your pipes. This can happen due to soil erosion, an earthquake, or an underground stream. A slab leak caused by this kind of pressure might be extensive and potentially damaging. If ignored, it can cause flooding.

Poor Water Quality

Check your water’s pH level. The normal pH level falls between 6.5 and 8.5. If your water is too acidic or too alkaline, the pipes inside or underneath your slab will start to disintegrate and fail over time. To combat this issue, you can call a reliable plumber in Scottsdale, AZ, from Zippity Split Plumbing for water softener installation.


If the pipes rub against gravel, concrete, other lines, or other materials, the consistent friction can cause wear and tear and eventually spring leaks. Hot water pipes are the most susceptible to abrasion because they expand when hot and rub against chippings or concrete surrounding them. Professional slab leak detection services can help prevent abrasion and subsequent leaks.
