How to Prevent Slab Leaks from Happening

Slab leaks can be devastating. Once the moisture from a slab leak invades your home, you can run into trouble with mold and mildew, have your flooring ruined, and worse. The good news is that you can play a role in helping to ensure that you don’t get a slab leak, at least not one that could be preventable. Find out how you can prevent slab leaks from happening and potentially ruining your home or property.

First, what is a slab leak?

Slab leaks are water pipe leaks or breaks that occur when the pipes run through a concrete slab, which is the foundation of the home. Many Southern California homes are built on a concrete slab, so the problem of slab leaks is common in the area.

Slab leaks are caused by when the foundation shifts or by corrosion found in the pipes.

We cannot control when the foundation of our property shifts, however, we can control the corrosion that can happen in our pipes.

How to Prevent Slab Leaks

Water Pressure

Do you hear a loud clunking sound when you turn the tap on or off? This indicates that your water pressure is too high, and every time you turn on the water, your pipes get a shock. Over the years, this causes undue wear and tear on your pipes. Any corrosion-protective layers on your pipes will be worn away by these frequent shocks.

The good news? You can adjust the water pressure gauge in your home to lower the water pressure

pH of Your Water

Not sure how acidic or alkaline your water is? Get an inexpensive test kit online to find out what your levels are like. You’ll be looking for a neutral pH, which would show up as a 7 when referring to the pH scale. Anything lower than 7 is considered acidic, and anything higher than a 7 is considered alkaline. Water that is acidic or alkaline can do a number on your pipes and cause corrosion and eventually leaks over the years. If your test shows that you have acidic or alkaline water, you may want to consider having a professional plumber install a special machine that will adjust your water’s pH.

Water Hardness

Water hardness or softness refers to the amount of mineral content in your water. Hard water has more mineral content in it, and soft water has less. Water that is too hard or too soft can corrode your pipes and even cause metal deposits to enter into your drinking water. While many municipalities take care of this issue before the water reaches your home, it’s always good to double-check. Have a professional evaluate your water hardness, and if necessary, recommend a water softener device to control the water hardness levels in your home.


Do you head for the Drano every time you have a clogged or sluggish drain? If you do, you may be sacrificing the long term health of your pipes for a short-term fix. Over time, the heavy alkali or acidic chemicals you pour down will not only eat through whatever is clogging them but through your pipes as well! Eventually, you’ll face a slab leak, which is much more costly and problematic than a clogged drain. Instead of using chemicals, call your plumber for persistent clogs for a solution that’s effective, yet safe for your pipes.

By following this advice, you can avoid the leaks you have control over. It won’t guarantee that you never get a leak, but if you do, it will likely be due to other issues such as shifting in the foundation.
