house pumps; two similar low pressure house pumps 

 and two high pressure fire pumps. The details of 

 these pumps are given in the introduction to the 

 chapter on Mechanical Plant. 



These six pumps can all be used for fire purposes 

 combined with the Fire Department steamers. The 



two low pressure pumps supply water to four house 

 tanks on the 13th Mezzanine floor, of a combined 

 capacity of 6,000 gallons, all cross connected for 

 house supply and fire purposes. 



All water used from the 13th floor to the basement, 

 in the four buildings, is supplied from these tanks.
