There is a danger of steam emissions with safety relief valves, therefore a discharge pipe must be
connected to the ¾" internal thread of the safety valve assembly.
The minimum dynamic head for the inlet water should be available at the pump inlet during
operation to ensure satisfactory bearing life, quiet running and to avoid cavitation.
The pump must not be run dry or against a closed discharge valve.
