Rule Automatic bilge pumps eliminate the need for a separate float switch to activate
the pump. Once power is supplied, starting and stopping is completely automatic.
The pump checks for water every 2 1/2 minutes (20 seconds for model 25SA-6WC)
by turning on for a second and measuring load against the impeller. If water is
present, the pump remains on until the water is removed. Thereafter the pump
resumes its 2 1/2 minute check cycle. The automatic pumps feature two positive
leads: an automatic (brown) and a manual override (brown with a white stripe).
