Pressure Reducing Valve (PRV)
A 3/4” PRV for the water supply or 1-1/4” for steam booster, is required if the incoming water
supply exceeds 20-22 PSI(138-151kPa) for water or 30 PSI for steam flowing pressure. The
PRV’s should be installed in the incoming supply lines before the machine connection.

Water Hammer Arrestor
Whenever a booster heater is installed in the final rinse line a water hammer arrestor shall be
installed between the booster outlet and the final rinse inlet valve. This helps to prevent the
knocking or hammering sound of the water as it flows through the pipes.
