Signs of Hidden Water Leaks in the Bathroom

Plumbing leaks are one of the most frustrating problems causing time and money loss. Most plumbing leaks originate near bathtubs, showerheads, sinks, and toilets. Some leaks are simple to detect and easy to fix. However, leaks hidden inside walls or ceilings cause more potential damage leading to expensive repairs. It is important to check for subtle changes in your bathroom, so you can detect leaks early before they cause damage. Plumbing leaks can potentially cause major structural damage. Early detection and consulting with plumbers in Oakland can save you money and avert potential disaster.

Here Are the Signs of Hidden Bathroom Leaks.

1. Damaged Walls

When the drywall is exposed to moisture, it softens and starts to bubble, causing warping and breaking into pieces. To fix the leak, Consulting with an expert plumber is necessary to avoid bad leaks. Certified plumbers will tear out the drywall and do patching and painting.

2. Mold Growth

Mold thrives in dark and wet environments. Pipes, concealed in walls or beneath flooring, offer the ideal environment for mold growth. If you see mildew or experience allergic symptoms like itchy eyes or wheezy breath, it is a potential sign of a hidden water leak. It is essential to clean the mold to prevent it from spreading to other parts of the house.

Remember that normally mildew grows wherever water collects, such as in the shower's corner. However, mold or mildew indicates a hidden water leak, as it will appear on non-shower walls or bathroom corners.

3. Increased Water Bill

If your water bill increases abnormally, you likely have a water leak somewhere in your home. Even small leaks can cause increased bills, wasting thousands of gallons of water and running up your water bill. You can check your water meter by turning off all the faucets in your home. If the meter is still running, you have a potential water leak.

The U.S. Environmental Protection Agency recommends that homeowners assess their winter water usage during January or February.

4. Low Water Pressure

If you have low water pressure, you have a plumbing leak somewhere. This might go unnoticed when the leak is small. However, any fluctuation in water pressure may indicate a leak, and calling a professional ensures a permanent solution. Often, a hidden leak is not discovered by homeowners until their water pressure is completely low. You can check the water pressure by turning off all the faucets. If the pressure is lower than usual, there is a potential water leak.


Catching problems early and calling professional plumbers will help reduce the risk of damage, helping you save a lot of time and money. Even a minor leak can cause major damage if left unattended. Adopting the DIY approach can help unless you have experience in plumbing and detection. If you suspect or see signs of a hidden water leak in a bathroom, call a professional for help right away.
