5 Warning Signs of a Slab Leak Every Homeowner Should Know

Slab leaks: two words you never want to hear! These sneaky little buggers can cause some serious damage if left unchecked. But don’t worry, we’re here to arm you with the knowledge you need to spot them early. At Arrow Plumbing & Drain Services, we’ve seen our fair share of slab leak scenarios, and trust us, early detection is your best friend.

So, what exactly is a slab leak? It’s when a pipe located under your concrete foundation springs a leak. And, unfortunately, because it’s hidden, it can be tricky to detect. But fear not! Here are 5 warning signs you should be on the lookout for:

1. Warm Spots on the Floor

If you notice a warm or hot spot on your floor, especially on concrete or tile, it could indicate a hot water line leak under your slab. That warmth is the heated water escaping and transferring through the concrete. This is a huge red flag!

2. Sudden Spike in Your Water Bill

Have you noticed your water bill creeping up for no apparent reason? You haven’t watered the lawn more, no extra laundry, nothing changed in your water usage? A sudden, unexplained increase in your water bill is a classic sign of a hidden leak. All that water has to be going somewhere, and if it’s not in your toilets or faucets, it might be under your slab.

3. Low Water Pressure

If your shower suddenly feels like a gentle trickle instead of a powerful spray, it might be more than just a bad day. A slab leak can cause a drop in water pressure as the water escapes from the pipe before reaching your faucets and showerheads.

4. The Sound of Running Water (When Nothing’s Running)

This one’s a bit creepy, right? If you hear the sound of running water when all your faucets and appliances are off, it’s time to investigate. That sound could be water escaping from a pipe under your slab. Listen carefully, especially in quiet areas of your home.

5. Damp Spots or Mold Growth Along Your Foundation

Water always finds a way. If you notice damp spots or mold growth along the base of your walls or where the floor meets the wall, it could be a sign that water is seeping up from a leak below. This is particularly concerning as mold can cause health problems and further damage to your home.
