How to Detect and Prevent Water Leaks

Water leaks are a common and troublesome plumbing issue in home and commercial spaces. In the U.S., it’s estimated that about 1 in 10 homes experiences a water leak each year. In addition, nearly 10% of homes have leaks that waste 90 gallons or more of water per day, according to the EPA. Apart from wasting water, leaks can damage various components of your home. Fortunately, it’s possible to detect and prevent water leaks in your home.

In this blog post, the skilled plumbers at Mr. Rooter Plumbing share tips on how to detect and prevent water leaks in your home. As seasoned water leak repair specialists, we know the telltale signs that indicate the presence of water leaks and what you can do to prevent them.

Signs of a Hidden Water Leak

Not all water leaks are easy to spot. Some develop behind walls, under floors, or within the foundation of your home. That’s why it’s important to watch for clues, including:

  • Unexplained spikes in your water bill: If your water usage hasn’t changed but your bill has, there could be a leak somewhere.
  • Water stains on walls or ceilings: Discoloration or warping can point to a leak behind the surface.
  • Mold or mildew smells: A persistent musty odor inside your home is a sign of trapped moisture.
  • Running water sounds: If you hear water running when no taps are open, it could indicate a hidden leak. Reach out to a professional plumbing company for water leak repair if you’ve noticed running water sounds in your home.
  • Soft or sagging flooring: Moisture from leaks can cause wood, laminate, or tile floors to warp or give way.

If you notice any of these signs, it’s best to call a plumber or use leak detection technology to find the source of the problem.

How to Detect Water Leaks

There are a few methods you can use to find water leaks in your home:

  • Check the water meter: Turn off all faucets and appliances, then monitor your water meter. If it continues to run, there’s likely a leak.
  • Use food coloring in the toilet tank: A common source of unnoticed leaks is the toilet. Drop a few drops of food coloring into the tank and wait 10-15 minutes. If the color appears in the bowl, you’ve got a leak.
  • Install smart leak detectors: These devices alert you to moisture in areas like basements, under sinks, or behind appliances. Many connect to your smartphone for real-time updates.
  • Hire a professional plumbing service: Experts use specialized tools such as acoustic sensors, thermal imaging, and pressure tests to find even the hardest-to-detect leaks.

Tips for Preventing Water Leaks

Prevention is always better than cleanup. To reduce the chances of a leak occurring in the first place, consider the following tips:

  • Inspect pipes regularly: Check under sinks, around water heaters, and behind appliances for signs of corrosion or wear.
  • Insulate exposed pipes: Cold weather can cause pipes to freeze and burst. Pipe insulation helps prevent this.
  • Replace worn-out washers and fittings: Old or damaged fixtures are more prone to leaking. From showerheads and faucets to kitchen sinks and pipes, even small cracks or worn-out seals can result in continuous water loss and hidden damage behind walls or under cabinets. Get in touch with a plumbing service for fixture replacement.
  • Schedule annual plumbing maintenance: A licensed plumber can catch small issues before they become big problems.

This will save you a lot of money down the road and give you peace of mind. If you need professional help, get in touch with Mr. Rooter Plumbing.
