Common Causes &  Signs That You Have A Slab Leak.

Those who live and work in Orange County know that earthquakes are simply a part of life. However, this reality can wreak havoc on the foundation and structural integrity of any home. With a large majority of Orange County homes built on a slab of concrete, it is not uncommon for homeowners to run into slab leak problems. These slab leaks can strike on hot or cold water lines and can appear on any drain line from any home appliance that uses water. It is important for homeowners to know both what causes slab leaks and how to identify one.

What is a Slab Leak?

A slab leak is an industry term used to describe a leak that has developed in the copper water lines running below the concrete foundation of your home. When these same leaks are above ground, in the wall or ceiling, they are known as pinhole leaks. Such leaks are often a result of long term corrosion to copper pipes.

Slab leaks can be found either on the pressure side or the drainage side of your foundation. If the slab leak is on the pressure side of the drains, it can typically be unearthed prior to triggering a lot of destruction. While these leaks are usually found quickly, they can cause significant damage. Leaks on the drainage side can be considerably more veiled, making them trickier to spot. They can leak for ages, showing no external indication. Slab leaks can make your foundation collapse. To stop this from happening, the plumbing must be examined frequently.

Since slab leaks are not clearly visible to a homeowner, they can often go undetected for long periods of time. Leaving a potential slab leak unattended can lead to much larger problems, such as mold damage and termite infestation. With that said, you can look out for more subtle signs that may indicate you have a slab leak.

What Causes a Slab Leak?

Pre-Damage and Poor Installation
It’s not unusual for some materials to get a little banged up when building a home, but if it’s the pipes that experience any damage, it could cause problems in the long run. Furthermore, if the pipes are installed incorrectly from the start, there’s a good chance that they won’t be able to function properly once they have an entire house sitting on top of them.

Ground/Foundation Shifts
Sometimes, slab leaks occur as the result of your house shifting on its foundation. When the ground of your home starts to shift, your pipes are bound to experience a little pressure. However, while pipes are strong and can withstand a lot of things, too much pressure can really take a toll and cause them to leak.

Abrasion
Pipes naturally expand and contract as water flows throughout them, but doing so can cause trouble depending on how your home was built. If the pipes are in a place where they are exposed to concrete, gravel, even other pipes, they could start to rub against them (until they eventually wear down) if they don’t have enough room to expand.

Corrosion
Since these pipes are located underground, it’s only natural for them to come into contact with soil. However, the addition of soil can cause the pipes to corrode over time. This is very common in home plumbing systems with copper pipes.
