Water Bill Suddenly High? Troubleshoot in This Exact Order
A bill spike is a fact with a short suspect list, and the list has a correct interrogation order: cheapest and likeliest first. Most La Puente households can clear or convict every suspect in an evening with food coloring, a flashlight, and the meter, and the ones who cannot arrive at the phone call with the search already halved. Here is the order. The call, when the evening ends there, is (626) 898-6169.
Suspects one and two: the toilets, then the meter
Start with the silent champion. A flapper that no longer seals sends tank water to the sewer invisibly around the clock, and multi-bathroom homes routinely host one quiet offender. Dye every tank, drops of food coloring, twenty minutes, no flushing, and color reaching any bowl convicts that toilet for the price of groceries; the tank-side page covers the two-dollar fix. Clean dye everywhere moves you to suspect two: the fifteen-minute meter test with the whole house at rest, which asks whether any pressurized line is losing at all.
A still meter after clean dye is genuinely informative: your spike lives in usage or in gravity-side territory, not in supply pipe, and the interrogation shifts accordingly.
Suspects three and four: the controller, then the buried lines
Irrigation confesses next. Check the controller for programs you forgot, overlapping schedules, or a rain sensor that died years ago, administrative leaks that out-waste real ones, then run the meter test again with irrigation isolated at its tie-in valve. Creep that stops under isolation convicts the irrigation network, and zone-by-zone testing assigns it to a valve circuit; creep that continues points at the domestic side’s buried runs, service line first. The hydraulics page and the service-line page carry each branch of that fork.
Summer spikes deserve one extra honesty check against the season: pools evaporate and lawns drink in a La Puente July, so compare against last summer’s bill, not last month’s.
When the evening ends at the phone
Some spikes survive every free check: dye clean, house-at-rest meter moving, irrigation isolated and innocent. That combination has narrowed the field to buried or hidden pressurized lines, exactly the territory where professional tracing, listening, and correlation earn their fee, and your evening’s log means the visit skips the preliminaries. Expect the sequence our pinpoint page describes: independent methods converging on a mark, priced repair options, and a bill that stops writing checks to the soil.
The worst strategy, for the record, is waiting a second billing cycle to be sure. The meter was sure the first time.
Run the order tonight
Dye, meter, controller, isolation: one evening, mostly free, and the spike either dies at home or arrives at our dispatcher pre-diagnosed. Either ending beats paying the leak’s subscription another month: (626) 898-6169.
