Tips for Checking for Leaks
If your water use is higher than expected, one of the first things to check is for leaks. Even small leaks can waste hundreds of gallons of water over time and may go unnoticed.
Start by inspecting these common areas:
-
Toilets
- Toilets are one of the most common sources of household leaks.
- Your toilet should only make noise while it is actively flushing. If you hear hissing or water running after the tank has refilled, it may indicate a leak.
- You can also place a few drops of food coloring in the toilet tank and wait 15 to 20 minutes without flushing. If color appears in the bowl, the toilet likely has a leak.
-
Faucets, Showerheads, and Bathtub Fixtures
- Check for dripping faucets, showerheads, and bathtub taps.
- Look beneath sinks and inside cabinets where water lines connect to the plumbing for signs of moisture, corrosion, or slow leaks.
- Washing machines and dishwashers
- Evaporative (swamp) coolers
- Water heaters
- Irrigation systems, hose bibs, and outdoor spigots
- Any other water-using appliances or connections
Look for dripping water, pooling, corrosion around fittings, or other signs of a leak. Replacing worn washers, tightening loose connections, or repairing faulty fixtures can often resolve the problem quickly.
