On ordinary work, the hot-water supply is run from the hot-water main, and ends at the fixture which it supplies. 4 shows a unitary water meter assembly 50, wherein the water flows vertically as it approaches and departs the respective meter.
For large apartment buildings, office buildings, etc., it is far more satisfactory and more economical to provide a large tank heated by a special heater. Each ancillary water meter provides the building owner with information on cold water consumption and hot water consumption by each apartment tenant. 4, the water meter assembly is located in a wall between two vertical wall studs 56, 56.
