Guest-room drinking water cannot be checked only at the main-unit outlet. Production, storage, circulating piping, and points of use all need corresponding design, cleaning, testing, and management responsibilities.
Define the supply method and intended use first
Record drinking-water point locations, user numbers, usage periods, supply method, and the existing piping network. Bottled supply, production for immediate use, and centralized piped supply involve different management responsibilities. One main-unit parameter sheet cannot replace all requirements.
Define the scope from raw water to the point of use
Record equipment and connections in sequence from raw water through pretreatment, production, storage, distribution, and points of use. Tank cleaning, vent protection, piping, and point-of-use maintenance all require corresponding arrangements. One test of the treatment unit's outlet water cannot automatically prove long-term water quality at points of use.
Acceptance and operating tests must match the subject being assessed
For drinking-water applications, check the current GB 5749-2022 and other applicable requirements. Relevant project professionals must confirm the scope of application and testing arrangements. Sampling locations, items, dates, testing organizations, and results must be traceable. TDS or sensory observations cannot replace complete applicable testing.
Documents to prepare
| Item to check | Information or records | Confirm the application |
|---|---|---|
| Treatment outlet | Equipment, operating conditions, and sampling records | Check the main-unit task |
| Storage and distribution | Tanks, piping, cleaning, and circulation arrangements | Define the management stages |
| Points of use | Locations, sampling, and abnormal-condition records | Match the final intended use |
