Signs You May Have a Cold Water Pipe Leak
Many leaks remain hidden behind walls, under floors, or in underground pipes, making them difficult to detect. Here are some common warning signs that indicate you may have a leak:
Unexplained Increase in Water Bills – A sudden spike in your bill could indicate a hidden leak.
Damp Spots or Water Stains – Discolored walls, ceilings, or floors may signal water escaping from pipes.
Mold or Mildew Growth – Excess moisture from leaks can lead to mold infestations, affecting indoor air quality and health.
Low Water Pressure – If your water pressure has dropped unexpectedly, there could be a leak reducing flow.
The Sound of Running Water When No Fixtures Are In Use – If you hear dripping or running water behind walls, a leak may be to blame.
Cracks in Walls or Foundation – Long-term water exposure can weaken your home’s structure, causing cracks and instability.
If you notice any of these signs, don’t wait! Early leak detection can prevent costly water damage and health hazards.
