The occasional plumbing leak is to be expected from time to time. But the leaks you can see are typically contained and repaired much quicker than hidden plumbing leaks throughout your home, which can persist for much longer and cause much more damage. Here are four signs of a hidden water leak in your home.

Water Damage

1. Sagging Drywall

When drywall becomes saturated with water, it becomes soft to the touch and may even start to sag or bloat. If you notice drywall in your home that is starting to become deformed, there is probably a leak in the plumbing behind that wall that should be repaired immediately.

2. Discoloration

Water from leaks may travel a long way from its original source before becoming visible in the home. As it travels, it picks up dirt and sediment hidden in the walls of your home. When it finds an exit point through a crack or drywall, the collected dirt leaves a stain. Water marks on your walls or ceilings are a definite sign of a plumbing leak.

3. Mold Growth

Mold tends to grow in dark, damp areas, so hidden leaks are often the site of substantial mold growth as well. While you may be able to see mold growth near damaged plumbing, you may also notice a change in your household’s health. Mold is known to cause respiratory illnesses, inflame allergies, and even cause skin and eye irritation.

4. Rising Water Costs

You’ll know you have a leak in your home if your water bills continue to rise for no reason. A great way to confirm this is to turn off all water-using appliances in the home and check your water meter’s leak indicator. If the indicator is moving, then water is moving somewhere into your home.
