How to Spot a Hidden Broken Pipe Before It Wreaks Havoc

 A broken pipe is every homeowner's nightmare, especially when it happens out of sight. Hidden behind walls, under floors, or in crawl spaces, a leaky or broken pipe can go unnoticed for days or even weeks, silently causing water damage, mold, and structural problems. Catching the problem early is key to avoiding major repairs. But how do you spot a broken pipe that you can't see? Here are some signs and steps you can take to spot the problem before it gets out of hand.

Watch for Unexplained Water Damage

One of the first signs of a hidden broken pipe is water damage without an obvious cause. Watch for wet spots on walls, ceilings, or floors, especially if they feel soft or spongy to the touch. Discoloration, peeling paint, or peeling wallpaper can also indicate moisture buildup behind surfaces. If these symptoms occur in a specific area, it’s worth investigating further.

Listen for unusual sounds

If you hear hissing, dripping, or running water when the toilet is turned off, it could mean there’s a leak in the wings. These noises are often more noticeable at night when the house is quiet. Walk around your home and listen carefully near the walls and floors where pipes run, especially in the kitchen, bathroom, or laundry area.

Check for a drop in water pressure

A sudden or gradual loss of water pressure in one or more faucets can indicate a burst pipe or leak. If your shower suddenly isn't as strong or a faucet seems sluggish, it could mean that water is leaking somewhere else before it reaches the faucet. This is especially true if the drop in pressure is limited to one part of your home.

Check your water meter

Your water meter can be a valuable tool for spotting hidden leaks. First, turn off all the water in your home, including appliances like dishwashers and washing machines. Then, check your water meter and write down the reading. Wait 30 to 60 minutes without using water and check again. If the meter has moved, it probably means there's a water leak somewhere in the system.

Look for (and smell) mold and mildew

Persistent moisture from a hidden burst pipe creates an ideal environment for mold. If you notice a musty smell or see mold growing on your walls or ceilings, especially in places where it shouldn’t be, it could be due to a hidden leak. Mold often forms in corners, behind furniture, or around baseboards, where water collects unnoticed.
