1. (1) The licensee shall ensure:

   1. (a) water supply systems are designed to supply water at high enough pressure to operate any fixtures and equipment during maximum demand periods;
   2. (b) water distribution systems are arranged to provide for continuous hot water at each hot water outlet;
   3. (c) thermostatically controlled automatic-mixing valves regulate the hot water provided to resident tubs, showers, whirlpools, and handwashing facilities at temperatures for comfortable use within a range of 105 to 115 degrees F, and these valves are installed on the recirculating system or on individual inlets to appliances;
   4. (d) water heating systems provide capacity at the minimum temperatures and amounts indicated in Table 3, Hot Water Use;
   5. (e) water temperature is taken at the point of use or inlet to the equipment;
   6. (f) rinse water at the warewasher is provided at 180 degrees (F) or 82 degrees (C) and may be provided by booster; and

   7. (g) the system can provide hot water at temperatures of 160 degrees F or 71 degrees C at the laundry equipment as needed.
