1. purified water without the installation of the PID map
2. purified water station did not paste the sampling point number
3. purified water needs to be added to the point of water use number; the first floor of the pipeline above the purified water storage tank no Flow direction marking;
4. purified water physical and chemical testing records: non-volatile matter test weighing without the original printout; conductivity test should be added to the unit; the whole record is too coarse, not strong operability
5. purified water system from the EDI out of the purified water, but the site of the piping and valves, pumps, pressure gauges have not been in accordance with the standards of purified water, there is a risk of contamination.
6. Purified water verification did not verify whether the action of the automatic solenoid valve is accurate.
7. Installation of purified water online conductivity monitoring without drawings.
8. Purified water without management design drawings, piping non-hygienic connections, no daily monitoring, piping design is not conducive to sampling.
9. Purified water irrigation and welding does not meet the requirements,
10. Purified water without sampling records; purified water return should be installed at the flowmeter
11. Purified water system needs to be the total delivery, total return, storage tanks, the furthest point of water use weekly full inspection, the rest of the water use point monthly full inspection
12. Verification of purified water system
13. Purified water design, installation, ozone disinfection basis, welding, verification confirmation and other parts do not meet the requirements
14. Purified water drawings do not match the actual, each control valve should be indicated in the drawings;
15. Pipelines, storage tanks, welding problems
16. Reserve spout, back to the spout should have a thermometer in order to control its temperature changes, there should be flow monitoring meter
