Role in the Amano resource system
How a commercial service team can use this page
Use this page when checking whether a commercial pool has enough verified flow and runtime for circulation, treatment equipment, and an Amano installation. Route scheduling cannot substitute for the design documents, actual flow, or adopted operating requirements.
Diagnose before changing the water
What may be behind the result or symptom?
Start with the last known-good condition and ask what changed. More than one factor may be present, and the same symptom can have different causes.
| Possible factor | Why it belongs in the investigation |
|---|---|
| Flow differs from the label | Valves, filter loading, pump speed, and plumbing resistance can change actual flow. |
| Operating demand changes | Heavy use, heat, debris, or a treatment event can change the required circulation window. |
| Equipment dependencies | Heaters, feeders, controllers, and other devices may require flow or an interlock. |
| Local requirements | Commercial facilities may have prescribed circulation or turnover requirements that a generic runtime cannot override. |
What should you check first?
- Review the pool design, pump curve or controller settings, filter instructions, and adopted operating requirement.
- Verify actual flow and filter condition rather than estimating runtime from pump horsepower alone.
- Confirm that treatment equipment and safety interlocks operate correctly throughout the planned schedule.
- Record the schedule, flow evidence, pool conditions, and any change so the next operator can evaluate the result.
A reading is not a dosing order
Do not copy a universal dose from another vessel or product. Verify the test, actual water volume, product identity, operating target, protective equipment, and required response. Then follow the exact label and governing procedure.
What can the observation not prove?
Clear water and a quiet pump do not prove that turnover, filtration, treatment, or local requirements are being met. Runtime alone is not a water-safety measure.
Keep the original result, repeat result, method, sample point, actual time, recent treatment, visible condition, equipment state, decision, and follow-up together. A record is most useful when it preserves uncertainty instead of quietly replacing it.
Where does Amano fit?
Amano needs a qualifying commercial return-line installation with at least 40 GPM and 10 PSI at the install point. It tests water on its schedule; it does not set pump runtime or override equipment instructions.
Amano uses liquid reagents and normally tests twice daily on adjustable timing. It measures free chlorine, combined chlorine, pH, and total alkalinity only. It saves timestamped readings, can send post-test alerts, and uses built-in cellular. It does not dose or replace manual tests, inspections, local code, facility procedures, labels, equipment instructions, or operator judgment.

Frequently asked questions
Is eight hours the right pump runtime for every pool?
No. A fixed number cannot account for actual flow, vessel volume, equipment, demand, or local commercial-pool requirements.
Can pump horsepower determine runtime?
Not by itself. The useful input is actual system flow under operating conditions, together with the design and governing requirements.
