Frequently Asked Questions
How do I measure a dripping faucet?
Count the number of drips in 10 seconds and multiply by 6 to estimate drips per minute. 15,140 drips ≈ 1 gallon (EPA approximation).
What’s a typical water rate?
Rates vary by region and tiered pricing. Our calculators default to a U.S. average but allow you to enter your local rate per 1,000 gallons.
How can I estimate shower water use?
Multiply the showerhead flow rate (GPM) by duration (minutes) and by the number of showers. Low‑flow heads are ~1.8 GPM or less.
Do calculations include energy for hot water?
Shower calculations estimate energy for heating hot water (assumed 70% hot). Numbers are educational approximations.
