1. It is important to locate the electric pump where it will be dry and
clean and where it will be thoroughly accessible for proper care.
2. No pipes should be allowed to pass above the electric motor where
liquids are likely to drip upon it.
3. The suction or supply pipe must be as short and straight as possible
and must be air tight, as air entering the pump through the suction
reduces its capacity or prevents it from working altogether.
4. A tight foot valve and a strainer should invariably be used on the
bottom end of the suction pipe when the water is to be lifted from 8
ft. to 10 ft. below the pump. Where the lift is excessive or for any
reason the supply be limited, an air chamber placed on the suction
pipe near the pump will prove beneficial in preventing slamming of the
valves.
5. Provision should be made for draining both pumps and pipes in cold
weather by a proper application of frost cocks.
6. If the electric pump is kept _dry, clean and well oiled_, it will
prove the most desirable and least expensive apparatus to be had for
the service.
7. Ascertain the nature of electric current to be used. Direct or
alternating? Voltage? (If alternating, note phase and number of
alternations.)
8. Also record any unusual or peculiar circumstances connected with
the installation or operation of the apparatus; and if so, what?
