If your kitchen sink's water pressure has decreased slightly, you may suspect that you have a leaking pipe somewhere. However, if you cannot see any obvious signs, the damaged pipe may be hidden in the wall behind your sink. If you have a feeling this is the case, look for the following signs that you have a hidden water leak under your kitchen sink.

Dripping or Hissing Noises

Even if you cannot see any water leaking because the pipe is buried behind the wall or under the floor, you may be able to hear it. Depending on how bad the pipe is leaking, you may hear a dripping sound for a small leak or a hissing noise if a small stream of water is coming out of your plumbing.

To see if you hear any unusual noises, turn off all of the appliances in your kitchen for a couple of minutes, including your refrigerator. While the room is completely silent, open the cupboard beneath your sink.

If you hear one of the above noises, you most likely have a water leak somewhere. If you hear a hissing noise, the leak is probably severe and needs to be dealt with by a professional as soon as possible.

Presence of Mildew or Mold

Whether or not you hear a strange noise under your kitchen sink, look for the presence of mold or mildew along the back cupboard wall or on the floor beneath your sink. If there is a hidden leak, the water will soak the wood in both of these structures.

As the water saturates the wood, any dormant spores will be fed by the leak, making them grow quickly in the dark space. You will most likely see the mold or mildew growing in a specific pattern that mimics the direction of the leak's water flow, such as congregating in a small area or in a straight line.

Even if you do not see any growth under your sink, you may be able to detect a strong, musty odor. This odor could be caused by mold or mildew growing inside your wall or floor where the water leak is feeding it. Unless you have a plumbing professional take care of the leak, the fungi will continue to grow.

If you notice any of the above signs under your kitchen sink, you may have a hidden water leak. Contact a plumber so they can inspect your pipes and determine where the water is leaking so that they can make the necessary repairs to prevent any further water damage.
