When a connection is to be made between a service connection of the Water Department and the plumbing of any manufacturing or industrial plant or other premises in which a direct connection is to be made between such service connection and any steam or hot water pipes or boilers, other than ordinary house boilers or pipes carrying a private water supply or liquids under pressure, a swing check valve of a pattern to be approved by the Water Department, arranged to seat against the back pressure of such steam or other pipes, shall first be installed at the expense of the applicant between the meter and first fixture on the premises. The Water Department may refuse to install a service connection or to turn on the water until such check valve has been installed if, in its opinion, the omission of such check valve will work an undue hardship upon the Water Department or its existing consumers. The Water Department may hold the consumer or the owner of the property liable for any and all damages to its meters or other appliances occasioned by the neglect or refusal of such consumer or owner of the property to install such check valve.
