3. The system must be of sufficient capacity, but not less than 40 gallons (152 liters), to furnish enough hot and cold water under pressure for each of the following procedures, if such procedures occur on the mobile unit:

(a) Food preparation;

(b) Utensil cleaning;

(c) Sanitizing;

(d) Handwashing; and

(e) Mobile-unit cleaning.

4. The water inlet must be located so that it, and any tank vents, will not be contaminated by waste discharge, road dust, oil or grease, and the water inlet must be capped. The water filler hose must be equipped with an approved back-flow prevention device.

5. The water filler hose must be of an approved material and stored with the ends connected or covered when not in use. The water filler hose must not be used for any purpose other than supplying potable water to the mobile unit.

6. The water filler hose must be identified either by color coding or tagging.

7. The water system must be operable under all climatic conditions, including subfreezing temperatures.

8. If a tank is designed with an access port for inspection and cleaning, the opening must be in the top of the tank and flanged upward at least 1/2 inch (13 mm), equipped with a port cover assembly that includes a gasket and a device for securing the cover in place, and flanged to overlap the opening and sloped to drain.
