Don’t Ignore these Warning Signs of a Plumbing Leak in Your Home

Don Jones Plumbing • 8 October 2025

Plumbing leaks can start small, but if they go unnoticed, they can cause significant damage to your home. From structural issues to mold growth and high water bills, even a slow drip can turn into a costly problem if left untreated. Detecting leaks early is key to preventing water damage and saving money on repairs. At Don Jones Plumbing, we provide expert water leak repair in the greater Phoenix area. Here are four warning signs that you may have a plumbing leak in your home.


Unexplained Increase in Water Bills
A sudden spike in your water bill without any change in usage is often one of the first clues that a leak is present. Even a small, steady drip can waste a substantial amount of water over time. If your bill keeps rising and you can’t account for the extra water use, it’s worth having a plumber perform a leak detection test to find the source.


Water Stains or Discoloration on Walls and Ceilings
Dark spots, yellow stains, or bubbling paint on walls or ceilings can indicate water seeping from a pipe behind the surface. These stains often grow over time as the leak continues, and moisture trapped inside walls can lead to mold and mildew growth. If you notice any discoloration, it’s important to act quickly to locate the leak and prevent further damage.


Musty Odors in Certain Areas
A persistent musty smell can be a sign of hidden moisture from a plumbing leak. Mold thrives in damp environments, and even a small amount of water can create ideal conditions for it to grow. If cleaning doesn’t remove the odor, there’s a good chance water is leaking somewhere nearby.


Low Water Pressure
If you notice a drop in water pressure from faucets or showers, a leak could be the cause. When water escapes from a pipe before reaching the fixture, the flow weakens. While low pressure can also result from other plumbing issues, a leak should always be ruled out as a potential culprit.
