5 Sure Signs of Water Leaks and How to Detect Them

Do you suspect water leaks in your home? When it comes to water leaks and plumbing troubleshooting, being proactive can prevent small problems from becoming major issues. Let’s unpack the 5 sure-tell signs of water leaks in your plumbing system, how to detect them, and what to do when you spot them.

Sign #1: Water Bill Spikes

Have there been changes in your water bill? Check the history of your water bill for any significant increases or patterns suggesting an undetected leak. An easy way to do this is to compare the current month to the same month in the previous year and spot unusual increases or differences.

Sign #2: Foundation Cracks and Shifts

Are there new cracks around the home, or are cracks spreading? Sudden and frequent cracks in flooring or foundation may suggest seepage from a hidden pipe leak, causing damage to your foundation and other structural components. Keep an eye out for cracks in walls, floors, and significant shifts in your home's foundation.

Sign #3: Ticking Water Meter

Your water meter can be a handy tool in indicating water leaks in the home. To run a test, completely turn off all water sources. Then, take note of the current reading on the water meter (this is the starting point for your test). After about 15 minutes, check the water meter reading again—a quick increase could indicate a substantial and potentially severe leak, while a slower increase suggests a smaller leak.

Sign #4: Mold, Mildew and Wet Spots

Are there areas in your home that never really dry? Damp spots around sinks, toilets, and water heaters, and mold and mildew growth on floors, walls, ceilings, and non-humid areas are sure signs of water leaks. Persistent damp or musty odors, especially in areas like the basement or under sinks, could suggest hidden moisture and a potential leak since mold and mildew thrive in damp environments. Keep an eye out for consistently wet or damp areas, both inside and outside your home, which points to leaking pipes or a malfunctioning irrigation system.

Sign #5: Warm Spots on the Floor

Have you noticed random warm spots on your floor? Unexpected warm spots on your floor, particularly under concrete or tile, could suggest a hot water line leak beneath the surface. Keep track of how often the warmness occurs and at what time of day to decide if it needs attention.

Water Leak FAQs

Q: How do I compare water bills for water leaks?

A: Compare the current month to the same month in the previous year to identify any significant increases.

Q: Can a leak be present even if my water bill hasn't increased?

A: Yes, not all leaks result in noticeable increases in water bills. Monitor for other signs like musty odors, mold, or visible water damage.

Q: Are all water leaks visible, or can some be hidden from plain sight?

A: Not all leaks are immediately visible. Hidden leaks can occur behind walls, under floors, or in underground pipes.

Q: Are there any preventive measures I can take to reduce the risk of water leaks?

A: Regularly inspect plumbing fixtures, pipes, and connections. Consider installing a water leak detection system for early warning signs.

Q: Can landscaping affect the likelihood of water leaks in my outdoor plumbing?
