Compare the amount of water used and the length of the billing period first. Then look for running toilets, visible drips, irrigation changes, and unexplained meter movement when no water is being used.
Separate a higher bill from higher water use.
Start with the usage figure on the bill, not only the amount due. Note the billing dates and whether the current period includes more days. Think about changes such as houseguests, a pool refill, landscape work, or a new irrigation schedule.
If you have previous bills, compare similar periods and write down what changed. This helps distinguish a billing question for the water provider from a plumbing concern that needs a closer look.
Look for clues indoors and outdoors.
Listen for a toilet that refills when nobody has used it. Check accessible faucets, hose connections, and the area around fixtures for drips or dampness. Include irrigation in the conversation even when the concern first shows up on a household water bill.
EPA WaterSense recommends comparing meter readings during a period when no water is used. If the reading changes, a leak may be present. Remember that automatic devices can also use water; account for irrigation, ice makers, treatment equipment, and similar systems before interpreting the result.

Make a useful observation record.
Choose a quiet time when the household can avoid water use and note the start and end readings if your meter is safely accessible. You do not need to touch plumbing or operate a utility-owned valve to record a reading. If access is unsafe or unclear, ask the water provider for guidance.
- Date, time, and water-usage readings.
- Which automatic water-using devices were operating.
- Any fixture noise, damp area, or new landscape wet spot.
- Recent repairs, appliance changes, or irrigation adjustments.
Match the next step to what you found.
A visible fixture issue gives a plumber a starting point. Unexplained water use without a visible leak may need a more focused investigation. If the usage is unchanged but the bill amount is different, ask your provider to explain the charges before assuming a leak.
For actively spreading water, keep clear of electrical equipment and seek prompt help. Do not enter a flooded area to inspect the source.
