A quick-closing solenoid valve on a commercial dishwasher is causing banging pipes. What does the code require to control the resulting water hammer?

Giải thích

Quick-closing valves generate water hammer, and the code requires approved water hammer arrestors, typically installed near the quick-closing valve. Raising pressure would worsen the shock, removing check valves does not address the surge, and switching to cast iron is not the code remedy for water hammer on a pressurized water line.
