The owner of a high-rise multifamily residential building in Battery Park, Manhattan, faced a pressing infrastructure decision: replace an aging, gas-fired domestic hot water (DHW) system that could no longer deliver reliable, efficient service to residents.

Because mixing valves are crucial for preventing scalding, thermal shock and Legionella, the CPS maintenance team required a timely and safe solution to protect students and staff while enhancing water efficiency. 

Some existing systems were never hydraulically calculated. Some were designed around pipe schedules. Some have little or no remaining safety margin. Add a backflow preventer without understanding the available water supply, system demand and device pressure loss, and a system that once appeared adequate may fail to deliver.
