FREEZING WEATHER PRECAUTION: Subsequent to testing a piping system, valves should be left in an
open position to allow complete drainage.
t For detailed Operating Pressure, refer to Pressure Temperature Chart on page 114.
Install 5 pipe diameters minimum downstream from pump discharge or changes in direction to avoid flow
turbulence. Flow straighteners may be required in extreme cases.
