Few household surprises sting like a water bill that's doubled for no apparent reason. Before you blame the city or the rate schedule, work through the actual causes — in order of likelihood. Hidden leaks top the list, and they're findable.

Start with the meter

Do the meter test: everything off, watch the flow indicator for 10–20 minutes. Movement means a leak — full stop. No movement means your usage genuinely increased, and the hunt moves to toilets, irrigation, and behavior.

The usual suspects, in order

Running toilets are the most common non-leak cause — a flapper that doesn't seal can waste hundreds of gallons a day silently. Next: irrigation zones stuck on or broken heads (especially after mowing season starts), a pool auto-fill compensating for a leak, and houseguests or new routines. Rule these out before assuming the worst.

When it's a hidden leak

If the meter moves with everything off, you're looking at a slab leak, a service-line leak, or a wall-line leak. Shut the house main valve: meter stops = inside the house; meter runs = the service line from the meter to your home. Either way, that's a detection job — the leak needs pinpointing before anyone digs or opens walls.

Sandy-specific notes

Sandy City reads meters on cycle, so compare against the same month last year rather than last month. And remember: the service line from the meter vault to your home is your responsibility — a leak there bills you for every gallon until it's found.

Frequently asked questions

How high does a bill have to jump before I worry?

Roughly 20%+ over the same month last year with no lifestyle change is the threshold worth investigating. Smaller moves are usually seasonal.

Can the city tell me if I have a leak?

They can confirm unusual usage from their reads, but they can't locate the leak — that's a detection specialist's job.

Will a running toilet really move the bill that much?

Absolutely — a silently running toilet is one of the largest residential water wasters there is. Check toilets first; it's a five-minute test.
