Listen (Rather Than Look)
If you walk into your basement, listen carefully. If you hear running water sounding from a void, then you have a slab leak. If a pipe bursts underground you should be able to hear the trickle of wasted water eroding the foundation of your home.
This tactic only works in a basement. It will be difficult to hear a slab leak outside or under your kitchen floor, but that is not to say it’s impossible.
Surge in Water Bill
A spike in the price of your water bill does not necessarily mean a slab leak. A slab leak will increase your water bill, but you must first determine if another cause is responsible. You ought to thoroughly inspect your home to confirm that no other plumbing leak is present.
Cracking Foundation
Excessive moisture like the type emitted in slab leak can buckle the foundation of your home. If you notice cracks along the outside of your home, inside walls, or on floors, then you may be dealing with a monster slab leak.
What will really strike fear into your heart is a slab leak scenario that is far from rare. If you have a high concentration of top soil on your property, saturation will cause it to heave, and the ground could shift, collapsing the entire home. Now, before it gets this bad, signs will be obvious. Make sure you consult a qualified plumber like the ones employed at Parker and Sons to eliminate a slab leak immediately.
