a.Where quick-closing valves (for example, clothes washers, dishwashers, solenoid valves) are installed
b.On every lavatory
c.Only on hose bibbs
d.Only on the water heater cold inlet
Giải thích
The code requires water hammer arrestors where quick-closing valves are installed, such as clothes washers, dishwashers, and solenoid valves, because these create sudden surges. Ordinary lavatories, hose bibbs alone, and the heater inlet are not the specific quick-closing valve locations that trigger the requirement.
