A faucet, hose bib, tub spout, or sink drips for days or weeks and the water bill is higher than expected.
A small drip can become meaningful when it runs continuously. The cost can also include sewer charges if the utility bills sewer from metered water use.
Check first
Estimate drip rate, hours per day, and how many days it continued.
Check whether the leak drains indoors, outdoors, or into a fixture tied to sewer billing.
Compare gallons per day before and after the repair.
Use the water meter if the drip may not be the only leak.
Practical savings moves
Repair the drip promptly when safe and practical.
Check other fixtures after one leak is found.
Use the leak calculator to estimate water and sewer impact.
Ask about leak adjustment rules if the total was unusually high.
Avoid these mistakes
Do not dismiss a small drip that ran for a long time.
Do not ignore sewer charges tied to the same metered water.
Do not assume the faucet is the only leak if meter flow continues after repair.
