Signs You Have a Hidden Leak in Your Delaware Valley Home

Water damage on white drywall ceiling in a Philadelphia home.Finding a leak in your home isn’t always as simple as stepping into an unexpected pool of water. It’s important to be on the lookout for other signs that indicate there may be a hidden leak within your system, including:

  • Low water pressure: Abnormally low water pressure can be a sign that water is leaving your system through a leak before it reaches your plumbing fixtures.
  • Visible water damage: If you notice obvious water damage to your walls or ceilings, you need a professional to locate and resolve the damage.
  • High water bills: A spike in your water bill without increased usage usually means you have a hidden leak.
  • Mold and mildew: The presence of mold and mildew means excess moisture around the home, likely from a water leak.

What To Do if You Have a Hidden Leak

Have you noticed the signs of a hidden water leak affecting your plumbing performance?

The first step you need to take is to shut off the main water supply to prevent further damage to your system. Here’s how:

  1. Find the main shut-off valve for your water supply. It’s usually located near the main water pipe leading into your home.
  2. Shut off your water by turning the valve clockwise.
  3. Turn on all the faucets in your home to flush the remaining water out of your system.

After you’ve successfully shut the main water valve, it’s time to contact a knowledgeable plumbing professional.
