Your water bill spiked. Triage it.

Three checks, in order. Each one takes minutes and rules out a whole category.

Quick answer

If your water bill spiked, run a 20-minute triage before paying or panicking: check the meter with all water off (finds leaks), compare gallons per day against the same month last year (finds seasonal or billing-period effects), and read the rate table on the bill (finds tier and sewer changes). Each check tells you exactly what to do next.

Step 1
Check 1 — the meter test (leaks)

All water off, watch the meter 15 minutes. Movement = leak. Silent toilet leaks are the most common and are usually a cheap flapper fix. [1]

Step 2
Check 2 — gallons per day vs last year (usage)

Divide usage by billing days, then compare to the same month last year. Summer irrigation, houseguests, or a new appliance show up here.
Compare bills properly

Step 3
Check 3 — the rate table (price)

Same usage, higher bill? Look for a rate increase, a tier you crossed, or sewer charges tracking your water. It's printed on the bill — the analyzer can decode it for you.

Step 4
Then: prove the fix

Whatever you found, verify it worked: take a meter baseline now and re-check against the next bill. The One-Unit Savings Sprint walks the whole experiment.

FAQ

Occasionally — usually an estimated read catching up rather than a mistake. Ask your utility which recent reads were actual, and compare meter photos if you have them.

Then it's not an active leak: check billing days, season, tier crossings, sewer charges, and whether a past leak is still inside this billing period.

Many utilities credit part of a leak-driven bill once you show the repair. Ask for their leak-adjustment policy — our dispute guide covers the script.
