Your water bill jumped and you can't see a leak anywhere?
It's stressful: you don't know if it's a cheap toilet part, a billing mistake, or something hidden in a wall or under the slab.
Here's the deal before we start
About 2 minutes, 5 questions. At the end you'll have a best guess at which of three buckets you're in: a cheap fix you can do yourself, a meter/billing issue to raise with your utility, or a hidden leak worth paying a plumber to find. It's a guide, not a diagnosis.
If paid help isn't a fit for you, we'll say so and you leave with the free steps. "No" is a perfectly good answer at any point.
No thanks, just show me the free guideLet's find where it's coming from
1. How much higher was this bill than normal?
2. With every tap and appliance off, does your water meter still move over 10-15 minutes?
3. Food-coloring test: a few drops in each toilet tank, no flushing, wait 15 min. Color in the bowl?
4. Does the meter reading printed on your bill look higher than the meter shows today?
5. How many bills has this been going on?

I'll stop hereWhat fits what you told us
Free first: run the free bill check on your actual bill. It costs nothing.
If you want help getting money back from the utility: the optional Dispute Pack is $29 for dispute-letter help, leak-adjustment coaching, and 24 diagnosis credits plus 3 bonus credits. It does not find or fix leaks; a plumber does that.
See the Dispute PackFrom what you told us, you probably do not need anything paid. The free check and guides cover it.
Not for me, I'll go the free routeWhat happens next
Run the free bill check first. Your answers here stay in this browser only; nothing is sent to us. If paid help doesn't fit after the free check, don't buy it.
