PUMP SYSTEM FIELD CHECK OUT
A pump system should be periodically checked out. Since proper operation is so important, tracking its' performance on a regular schedule can eliminate an untimely emergency. During the check outs, reports will be generated on all tests and readings, compared to previous visits, and maintained in a file with all other pump station data. Intervals between check outs can be a week to three months, depending on manpower availability and importance of system.
STEP # 1)	Inspect the general condition of the lift station components. Look for grease in the pit, debris on the float switches, condition of the pump and switch cords, and dampness in the panel. If anything appears out of the ordinary, take corrective action.
STEP # 2)	Operate each pump in the "Hand" position. Check and record voltage and amp draw. Look for any leakage around the disconnect fitting. Observe vent hole and make sure the opening is not restricted.
STEP # 3)	Check the pump's insulation resistance with a megohmmeter. Record this data.
STEP # 4)	Operate the panel through numerous cycles to verify correct operation and sequencing. If floats are not accessible, use jumper wires as a substitute to the float switches.
STEP # 5)	Conduct a functional test on the pump's performance. Compare the results to those test done in the past. Record this data.
STEP # 6)	Upon completion of the check-out, enter all pertinent into a pump station log book for future reference.
