Avoid mold growth and health issues

Save money on water bills

Preserve your property’s value

Common Causes of Water Leaks

Leaks can occur for various reasons. Knowing what typically causes them can help you stay proactive:

Old or corroded pipes

High water pressure

Shifting foundations

Clogged drains or toilets

Poor installation or materials

Not to mention the other accelerators of salts air and moisture for the corrosion of pipes as in among others coastal cities like Costa Mesa, thus, another reason to always have a reliable plumber from Costa Mesa within speed dial. 

10 Signs You Might Have a Leak in Your House Without Warning

It's important to catch leaks early in order to minimize damages. Here are some red flags to look for:

1. Unusual Spike in Your Water Bill

You've neither changed your water usage habits nor increased your consumption yet your bill shows a sudden rise, it's time to do some digging to find a leak.

2. Musty Odors or Mold

Water leakage undiscovered leads to moist areas where molds and mildew can thrive.

3. Water Spots or Stains on Walls or Ceilings

Usually the sign indicating hidden moisture is dark patches, bubbling paint, or strips of paint peeling on wallpaper now visible.

4. Sound of Running Water

The sound of water running when no taps are on means there is something going on.

5. Low Water Pressure

Leaks in the plumbing can reduce overall water pressure.

6. Cracks in Foundation or Walls

Leaks beneath your slab can cause your foundation to shift or crack.

7. Warm Spots on Floors

If you notice unusual hot spots on your floor, it could be a hot water line leaking beneath the surface.

8. Visible Water Pooling

Puddles where they shouldn’t be — inside or outside your home — need immediate attention.

9. Lush or Green Patches in Your Yard

A hidden underground leak can make certain areas of your lawn unnaturally green or soggy.

10. Water Meter Keeps Running

Turn off all water sources and check your meter. If it's still moving, there’s likely a hidden leak.

DIY Leak Detection Tips

While professional leak detection is the most accurate, you can do some basic checks yourself:

Inspect faucets and under-sink plumbing for drips or wetness

Use food coloring in your toilet tank — if it appears in the bowl without flushing, you have a leak

Monitor your water meter before and after a few hours of non-use

Feel your walls and flooring for dampness

For anything beyond surface-level, it’s time to bring in a professional Costa Mesa plumber.

Tools Used by Professionals for Leak Detection

When DIY methods fall short, plumbers have advanced technology to pinpoint the problem:

Thermal Imaging Cameras – Detect temperature changes behind walls and under floors

Acoustic Listening Devices – Pick up the sound of water escaping pipes

A certified Costa Mesa plumber can use this specialized equipment to identify leaks with minimal property disruption.

Kitchens – Dishwasher and sink connections may leak

Laundry Rooms – Washing machine hoses can burst or leak
