A Guide to Identifying Hidden Leaks in San Jose, CA


A hidden water leak can be a silent destroyer of your San Jose, CA home. Here are some key signs that the experts at JLK Plumbing recommend you watch for.

  • An Unexplained High Water Bill: This is often the first and most obvious sign of a hidden leak. If your water usage habits haven't changed but your bill has spiked, a leak is a likely culprit.
  • Your Water Meter is Always Running: A simple way to check for a leak is to use your water meter. Turn off all water-using appliances in your home, then look at the meter. If the dial or leak indicator is still moving, you have a leak somewhere in your system.
  • The Sound of Running Water: If you can hear water running when no faucets, toilets, or appliances are on, it's a clear sign of a leak within your walls or under your slab.
  • Warm Spots on the Floor: If you have a concrete slab foundation, a warm spot on the floor can indicate a hidden hot water line leak underneath.
  • Visible Signs of Damage: Look for unexplained water stains on ceilings or walls, peeling paint, warped flooring, or the presence of musty odors and mold growth. These are all signs of a persistent moisture problem in your San Jose, CA home.
  • Reduced Water Pressure: A significant leak in your main supply line can sometimes cause a noticeable drop in water pressure throughout your home.If you notice any of these signs, don't wait. A hidden leak will only get worse. The professional leak detection service from JLK Plumbing in San Jose, CA uses advanced technology to find the exact source of the problem, allowing for a targeted and efficient repair.
