Water Leak Bill Savings
Estimate cost of drips and running toilets. Enter values for instant results with step-by-step formulas.
Formula
Cost = LeakVolume × (WaterRate + SewerRate)
The cost of a leak is the volume of water lost multiplied by the combined rate of water supply and sewage treatment. Because sewer fees are often tied to metered water usage, a leak charges you twice for water that simply goes down the drain.

Frequently Asked Questions
How much water does a drip waste?
One drip per second wastes over 3,000 gallons per year. That's enough for 180 showers.
How do I find a silent toilet leak?
Put a few drops of food coloring or a dye tablet in the toilet tank. Wait 15 minutes without flushing. If color appears in the bowl, you have a leak.
Are smart water monitors worth it?
Yes. Devices like Flo by Moen cost ~$500 but can save $10,000+ in water damage insurance claims by shutting off water automatically during a burst.
Can a faucet leak be fixed?
Usually yes. It's often just a worn washer or O-ring ($0.50). Cartridge faucets need a new cartridge ($20).
