check the valves and cup leathers. Before removing the pump, consult the
manufacturer's method for picking up the foot valve and for additional maintenance
procedures.
c)
Overhaul Procedures. Inspect the pump jack for wear each year.
Replace worn bearings and parts. Check the packing assembly and repack as
necessary. If the pump delivery is satisfactory, do not overhaul the pump parts in the
well. Paint the exterior of the pump as necessary.

Ejector Pumps
a)
Centrifugal Pump. Maintain the centrifugal pump portion of the
system according to the maintenance items listed for centrifugal pumps in par. 6.5.1.
b)
Ejector Assembly. Each year, or as directed by the utilities
manager, remove the ejector, the foot valve, and the screen from the well. Examine all
parts for wear and corrosion and repair or replace any defective parts. Paint the
exterior of the pump in accordance with par. 2.4.4.1. If practical, paint interior iron with

Starting a New Well Pump. Table 18 lists startup procedures for vertical
turbine well pumps. While plant operators will not generally be responsible for
performing these startup procedures, they may be charged with overseeing the
contractors performing installation and it is preferable that they are familiar with the
startup tasks. Figure 6 shows the necessary water-level checks. If problems occur,
refer to the troubleshooting checklist provided in Table 19.

Pump Drivers. Pump drivers provide the mechanical source of energy to
pumps. The driver is usually an electric motor, gasoline or diesel engine. More
detailed information on pump drivers is provided in par. 2.1.4.
6.6.1
Electric Motors. Electric motors are the most common drive used in
military water systems. Proper operation of an electric motor requires that the operator
be able to recognize the normal sounds and conditions of a properly running motor. In
general, investigate any change in the sound or operating condition detected during the
regular inspection. Table 20 includes a list of routine operating checks for electric
motors.
6.6.1.1
Maintenance. As a rule, the electrical shop is responsible for routine
maintenance of electrical motors. Under some circumstances, the responsibility for
