Ways to Detect a Leak: The Ultimate Homeowner’s Guide

919-777-4383

The U.S. Environmental Protection Agency (EPA) estimates that 10% of US homes have leaks and waste 90 gallons or more of water daily. Household leaks account for roughly 10,000 gallons of wasted water every year.

In addition to unnecessary wastage, leaks can have even more alarming effects. When undetected, they can cause significant damage, including mold, rotting wood, and warped floors. Foundation damage is also possible when water accumulates in hidden areas and can compromise your home’s structural integrity.

Detecting a leak early could help you avoid the damage, inconvenience, and associated repair costs. This comprehensive guide will assist you in recognizing signs of a water leak so you can protect your home.

Best Methods for Detecting A Leak in Your Home

According to the Morgan Law Group, water damage due to plumbing issues and leaks ranks among the eight most common homeowners insurance claims in North Carolina. Insurers may cover sudden and accidental water damage from leaks. However, they usually won’t cover damage from gradual leaks or poor maintenance. 

Ensure this doesn’t become an issue for you by using the following home leak detection methods:

Check for Visible Signs of Water

When there’s a leak in your home, visible evidence of water damage could appear within minutes, depending on its severity. Unfortunately, you’re more likely to notice the damage hours or days later as the moisture spreads causing further deterioration. Some of the more immediate signs of residential water damage include:

  • Dark spots
  • Deformation on walls and ceilings
  • Water stains
  • Peeling paint or bubbling wallpaper

Within a day or two there may be more pronounced discoloration, swelling, and potential mold growth. To find the source of the leak, follow the trail of water damage. You should also check for musty smells and damp patches, which can indicate hidden leaks.

Inspect Faucets, Fixtures, and Toilets 

What are some of the most common plumbing leak risks in a home? Dripping showerheads, faucets, and running toilets.

You should check all faucets and fixtures for drips or pooling water. If you discover a leak, tightening the connections, or replacing worn washers could resolve the issue.

Raleigh Realty advises homeowners to understand their water usage and cites the toilet as the largest contributor for most homes. You’ll want to ensure it’s not a source of a leak. 

You can do this by adding food coloring to your toilet tank. After placing a few drops, wait for 10 minutes without flushing. If there is coloring in the bowl water, you have a leak.

Monitor the Water Meter

Your water meter measures the volume of water that flows to your home and calculates the actual consumption reflected on your water bill. Monitoring your meter is one of the home plumbing checks that can help you detect leaks. 

Turn off all water sources and record the meter reading. Check the meter after 30 minutes; if the reading has changed, there’s likely a leak. You’ll need to determine if the leak is inside or outside by turning off the water at the stop tap and repeating the check. You should also review your water bill for any unexpected spikes, which could indicate a leak.

Call a Professional

DIY detection methods are your first line of defense against extensive damage from leaks and can be effective. But what happens if the issue isn’t resolved despite using all the methods for detecting a leak

Call a professional. A plumbing specialist will have advanced detection methods. These can help ensure they find the source of any leak in your home and may include the use of:

  • Acoustic equipment to locate leaks behind walls, appliances, and cabinets
  • Thermal imaging cameras to detect temperature variations for leaks under floors and in walls
  • Video pipe inspection to visually detect leaks
  • Ultrasound leak detection devices that use sound to pinpoint the exact site of water leakage

It’s also advisable to have contact information for an emergency plumber in Raleigh, NC especially if a pipe bursts or you have a gas leak.

Minimize Damage and Reduce Costs With Proper Home Leak Detection
