Detect and Chase Down Leaks by Gathering Clues at Home

Published on April 22, 2025

Easy to fix water leaks account for more than one trillion gallons of water wasted each year in U.S. homes, according to the EPA’s WaterSense program. The average household leaks more than 10,000 gallons of water per year. 

Many common household leaks are quick to find and easy to fix. Worn toilet flappers, dripping faucets and leaking shower heads are easily correctable and can save on your utility bills.

To check for leaks, start with your utility bill. If you see a spike for no reason that you know of, that’s an indicator. 

Next, read your water meter. It’s usually near the curb in the front of your home. Remove the lid when there is no water being used in the home. Check it again after two hours. If the meter does not read exactly the same, you probably have a leak. 

Next, take a toilet test. Put a few drops of food coloring in the tank and let it sit for 10 minutes. If color shows up in the bowl, you have a leak. Make sure to flush afterward to avoid staining, and consider replacing your old flapper if it is torn or worn. If you would like leak detection dye tablets, you can request them from the City of Melbourne Environmental Community Outreach (ECO) Division (321-608-5080).

Also, go throughout your house and listen for leaks in faucets, shower heads, under sinks and around appliances. Go outside and check spigots and irrigation systems. 

Check for any signs of mold or moisture on your walls, ceilings or floors. This could indicate that a pipe is wreaking havoc behind the scenes and requires the attention of a professional.
