How to Know If Your Home Has a Hidden Leak
Water Meter Reveals Inexplicable Water Usage
If you’d like to test whether or not there’s a leak somewhere in your home, you can do this using your water meter. Here is how to conduct the test:
Don’t use any water in your home for at least 30 minutes; this also means not turning on faucets or water-using appliances.
Go outside, and check your water meter for activity.
If your water meter shows that there was activity, even though no one was using any water, this proves that there is a leak in your home.Visible Mold or Mildew Growth
Leaks behind walls create moist, dark environments that allow mold and mildew to grow and thrive. Eventually, you might see mold growth forming on the wall closest to a hidden leak.
If mold is growing in an area that receives a high amount of moisture, such as a bathroom, it may simply be an indication that better ventilation is needed. However, if you see mold growth on a wall or the ceiling in an area where you would not expect, you probably have a hidden leak.
Musty, Mildew Odor
Sometimes you might not be able to see the mold or mildew that is growing as a result of a leak. However, the smell can give the problem away just as easily. If you catch a whiff of something musty, there’s a good chance that old water is collecting somewhere in your home that you can’t see.
Stained/Warped Walls, Ceilings, or Floors
When your home soaks up water, a variety of red flags can become visible, including ceiling stains, bubbling drywall, warped walls, and sagging floors. While these issues can be caused by excess humidity, they can also be signs that a pipe or plumbing connection has started leaking behind your walls.
Inexplicably High Water Bill
After a while, you get a general sense for what your water bill should be. If you own a pool or sprinkler system, your bill will tend to be higher during summer. However, if you receive a water bill that seems especially high, and you can’t figure out what caused it, then you may have a hidden leak somewhere that’s increasing your bill.
