Section 15.5-41 - Plumbing

(a) Plumbing shall be sized, installed, and maintained in accordance with 675 IAC 16. There shall be no cross-connection between the potable water supply and any nonpotable or questionable water supply nor any source of pollution through which the potable water supply might become contaminated.

(b) A nonpotable water system is permitted only for purposes such as air conditioning and fire protection and only if the system is installed according to law, and the nonpotable water does not contact, directly or indirectly, food, potable water, equipment that contacts food, or utensils. The piping of any nonpotable water system shall be durably identified so that it is readily distinguishable from piping that carries potable water.

(c) The potable water system shall be installed to preclude the possibility of backflow. Devices shall be installed to protect against backflow and back siphonage at all fixtures and equipment where an air gap at least twice the diameter of the water supply inlet is not provided between the water supply inlet and the fixture's flood level rim. A hose shall not be attached to a faucet unless a backflow prevention device is installed.

(d) If used, grease traps shall be located to be easily accessible for cleaning.

(e) Drains shall be constructed in accordance with 675 IAC 16.
