How To Check for a Water Leak when your Bill Spikes

An unexpectedly high water bill can be alarming for any homeowner. While minor fluctuations in water usage are normal, a sudden spike is often a sign that something isn’t right—particularly a hidden water leak. Catching these leaks early can prevent costly water damage and wasted water. In this article, we’ll guide you through the steps to identify potential water leaks in and around your home.

1. Check Your Water Meter for Leaks

Your water meter is the best place to start when investigating a potential leak. Here’s how to check for leaks using your meter:

  • Turn off all water: Ensure that no water is being used inside or outside your home (no faucets, appliances, or sprinklers).

  • Locate your water meter: The meter is usually located near the street or sidewalk in front of your home.

  • Observe the meter: If the meter continues to run even when all water is off, you likely have a leak somewhere in your plumbing system.

  • Check the leak indicator: Many meters have a leak indicator—this could be a small dial that moves when water is running. If it’s moving and everything is turned off, it’s a strong sign of a leak.

2. Inspect Common Leak Areas

Certain areas in your home are more prone to leaks. Start with these common trouble spots:

  • Toilets: A leaking or constantly running toilet is one of the most common causes of a sudden increase in water bills. If your toilet continues to run long after flushing, you’re likely wasting gallons of water each day. To test for a slow leak, add a few drops of food coloring to the toilet tank and wait 10-15 minutes. If the color appears in the toilet bowl without flushing, you have a leak in the flapper valve that should be repaired.

  • Faucets and Fixtures: Dripping faucets may seem minor but can waste a significant amount of water over time. Check all sinks, bathtubs, and showerheads for visible drips or moisture buildup.

  • Appliances: Check around water-using appliances like your dishwasher, washing machine, and refrigerator (if it has a water/ice dispenser). Look for damp spots, water stains, or pooling water near the base.

  • Water Heater: Examine the area around your water heater for leaks. A leaking water heater can lead to higher water bills and potentially costly damage if left unchecked.

3. Examine Outdoor Water Sources

Outdoor leaks can be harder to spot but can significantly impact your water bill:

  • Irrigation System: If you have an automatic irrigation system, check for wet spots in your yard, which may indicate a broken sprinkler head or underground leak.

  • Hose Bibs and Outdoor Faucets: Ensure that your outdoor spigots and hose connections are not dripping. Over time, these leaks can waste substantial water.

  • Pool: If you have a pool, monitor the water level regularly. A sudden drop in the water level may indicate a leak in the pool’s plumbing or structure.

4. Monitor Your Water Usage

Keeping track of your water usage over time can help you identify unusual patterns. If your bill is consistently higher than usual, compare your water usage from month to month. Many water providers offer detailed usage reports, which can help pinpoint when the increased usage started.

5. Call a Professional if You Can’t Find the Leak

If you’ve gone through these steps and still can’t locate the source of the leak, it’s time to call a professional plumber or home inspector. Hidden leaks can sometimes be located behind walls, under floors, or in your foundation, making them difficult to detect without specialized equipment.

Your local plumber can offer thorough leak detection services and offer a solution best for your concern.

A sudden increase in your water bill is often a sign that something is wrong. By following these steps, you can check for leaks and prevent further damage to your home. Regularly monitoring your water usage and inspecting common leak areas can save you money and help protect your property from water damage.
