Use consumption records to help narrow the fault.
Dripping Springs WSC provides customer water-usage monitoring information. If that is your provider, records of unexpected use can help frame a repair request, although they do not identify a fault by themselves. Compare the dates and times of unusual use with the irrigation schedule and known changes around the property.
Tell us whether the problem is continuous, limited to one zone or associated with a recent landscape alteration. Confirm current rules for operating the system during testing with the actual provider. Separate leak repair from redesign of coverage, and ask for a record of components changed. At commercial properties, identify the authorized contact for controller access and water interruptions.
