Signs of Slab Leaks

Signs of Slab Leaks

Common Slab Leak Symptoms

A slab leak is a problem probably more common than you think. It can happen in older homes or newer homes alike and can cause major damage if not caught early. The causes can be tricky to detect, but if you suspect you might have a slab leak, consult this list of slab leak symptoms to help narrow down your search.

slab leak symptoms

  • You hear water running in a hissing or splashing sound, but none of your faucets are on. Listen carefully behind washers or in the walls.
  • If you have a musty or mildew smell, you might have a leak in your slab.
  • If you start to see cracks in your tile floors or bubbles in your linoleum floors.
  • You might have a slab leak if there are “hot spots” under your floors where hot water may be leaking.
  • Another slab leak symptom is wet or cracked baseboards. As your foundation shifts because of the water, it will start to impact the entire home, even places that are nowhere near the leak.
  • There is water coming out below the water heater, but the platform is dry.
  • Another recognizable symptom is water on the floor or wet carpet without obvious reason.
  • Your water bill has skyrocketed without obvious reason. A pinhole leak in one of your pipes can leak out more than 10,000 gallons of water in just one month!
  • Read your water meter. Make sure that all of your faucets are off and your toilet isn’t running. The dial should not be moving. Also, if the numbers rise over a half-hour period with all water off, you know you have a leak somewhere.
  • Your water pressure has suddenly dropped. This could be a sign of a slab leak.

If any of these slab leak symptoms are occurring in your home, turn off all of your water and call your local plumber. The sooner you get it fixed, the better!
