5 Ways to Spot a Leak Before It Gets Worse

Water leaks may be small initially, but they may become costly issues in a short time. It can be hundreds of gallons in a month, pushed behind a wall drip or under the floor.

If you need quick, professional help, a trusted plumber in Orange from Rooter Man Plumbing of Orange County is always ready to fix leaks before they damage your home. But before you call, there are signs you can check yourself.

This blog breaks down five simple ways to spot a leak early—so you can stop the problem before it gets worse.

1. Check Your Water Bill for Sudden Spikes

Your water bill is often the first clue that something’s wrong.

Why This Matters

If you haven’t changed your daily water use but your bill suddenly climbs, it could mean water is escaping somewhere. Even a tiny leak, like a dripping faucet, can waste 3,000 gallons of water a year.

What You Can Do

• Compare your latest bill to the same month last year.

• Look for unexplained jumps in usage.

• If you see a steady climb, it’s time to investigate.

Pro Tip: Shut off all water in your home and check your meter. If it’s still moving, you likely have a hidden leak.

2. Look for Water Stains or Discoloration

Walls, ceilings, and floors often give away leaks before pipes burst.

Signs to Watch

• Yellow, brown, or copper-colored stains on drywall.

• Soft or sagging spots in ceilings.

• Warped wood flooring or bubbling paint.

Why It’s Serious

These stains show that water has been soaking into building materials. Over time, this can lead to mold growth, which affects indoor air quality and health.

3. Listen for Unusual Sounds

Water leaks don’t always show up visually—you might hear them first.

Common Noises

• Hissing or whistling from pipes.

• Running water sounds when no fixtures are on.

• Dripping noises inside the walls.

What to Do

Switch off all water-consuming appliances. Whether you hear noise yet it is a good indication that water is flowing where it is not supposed to.

Pro Tip: Find the sound with a stethoscope-like apparatus.

4. Watch for Damp or Musty Smells

Leaks often create odors before visible signs appear.

Why Smells Are a Warning

• The dampness is continual, and this allows mildew to grow and mold.

• It can take 24 to 48 hours before the development of mold due to exposure to water.

• Although you may not actually see any mold, that damp smell is an indication that there is moisture.

Action Steps

• Check under sinks, in crawl spaces, and around basements.

• Smell around damp-smelling walls or the floor.

• When the smell does not disappear, have it done by a professional.

5. Test Toilets and Faucets for Hidden Leaks

Some leaks happen in places we use daily but overlook.

Quick Toilet Test

• Add some food coloring to the tank of the toilet.

• Wait 10-15 with no flushing.

• In case of color appearing in the bowl, your flapper valve is leaking.

Faucet Check

• Turn off faucets and place a dry tissue around the base.

• Should it be wet after a few days, you have located a slow leak.

Pro Tip: Replacing a damaged flapper or washer costs little and may help to conserve hundreds of gallons of water per day.
