If your home's pipes run under the slab foundation of your front porch, you may suspect that one of them is leaking because you have started to see water accumulate around the concrete. If so, look for three other signs listed below that could indicate an underground leak.
One Of The Corners Has Started To Crack
Examine the corners of the slab foundation to see if there are any new cracks in the concrete. You may also notice that the corners are starting to point down toward the ground.
This could be a sign that you have a massive water leak that is deteriorating the concrete. It could also indicate that large amounts of water have made the soil so soft that the corners are starting to sink.
The Slab Is No Longer Even
Step back from the slab, and see if it is laying evenly on the ground. You may notice that one side is lower than the other, especially in the vicinity of puddles of water or cracked corners. You may also see cracks starting to form in the center of the concrete slab. This could indicate a massive water leak under the slab.
When large amounts of water saturate the sublevels of the soil, they become too weak to support heavy weight. Eventually, the slab starts to shift because the ground beneath it is giving way. If the leak continues unrepaired, a sinkhole could form and cause a severe depression on the surface of your yard, causing the slab and your porch to fall or crumble.
Bubbling Water Is Seen At The Edge When Water Is Running
Another test to see if you have leaking pipes underground is checking for the presence of bubbling water at the edge of the slab while water is running in your home. As the water forces its way out of the pipe and into the ground, air pockets are released into the water and pushed to the surface, where you can see them in the puddle of water.
Turn on several faucets in your house full blast, then go outside to check for air bubbles. If you see any, this is a sign that you have a major pipe leak underground, especially when accompanied by the other signs above.
If you notice one or more of the signs above, you may have a leaking water pipe under the foundation. For more information, contact Fixxer Company or a similar organization.
