pit peculiarities and is secured so the pump will turn
"on" and "off". It is recommended that the pit be 18"
in diameter or larger to accommodate both a primary
and a backup pump.
4. Check the installation of the primary and backup
pump floats to ensure that both move freely and are
not being encroached upon where the float cannot
move. Adequate space between the floats must be
maintained.
5. The pump should be manually activated once a month
by lifting the float rod. Let the pump run for at least 15
seconds to prevent the pump from building up calcium
deposits and debris, which could harm the pump.
Turbulence caused by high velocity
incoming water can negatively affect the on/off action
of the float mechanism. If this condition exists, the
incoming water must be baffled to avoid excessive
turbulence.
