9 Maintenance
Controller The controllers electronic has no moving or
wearing parts. It requires no maintenance. There are rubber
plugs to seal at the bottom, unused conduit holes. Inspect
them to insure that the controller is sealed from mois-
ture, insects, etc. Check that mounting and conduit hard-
ware is tight.
Motor The motor requires no maintenance. It has no
brushes or other frequently wearing parts.
Pump end The pump mechanism (pump end) is lubricat-
ed only by water and requires no maintenance. It may wear
after some years, especially if there are abrasive solids in
the water. If sand accumulates in the storage tank or pipes
as a result of normal pumping, it is best to take period-
ic measurement of the pump’s performance. A worn pump
end can be replaced in the field.
WARNING – If there is danger of
freezing, the pump must be drained
ahead of time. Also drain all pipes
subject to freezing.
