Question

water hammer is typically prevented by
○ pressure balancing faucets
○ thermostat mixers
○ single lever faucets
○ dead end risers
○ tempering valves

Explanation:

Water hammer is caused by sudden changes in water - flow velocity. Pressure - balancing faucets can help absorb the shock of sudden flow changes, reducing the likelihood of water hammer. Thermostat mixers are for temperature control, single - lever faucets are for ease of use in controlling flow and temperature, dead - end risers can actually contribute to water hammer issues in some cases, and tempering valves are for temperature regulation.

Answer:

pressure balancing faucets
