Check flow out of each row frequently to ensure orifices have not been plugged.
If fluid is allowed to sit in the lines overnight and the temperature drops below 32 degress fahrenheit it is
recommended that the orifices be removed and the lines be flushed before continuing operations. Many fertilizers can
salt out in temperatures under 32 degrees fahrenheit and clog oricfices.
