How the Automatic Sensing works
The “S” series automatic sensing RULE bilge pumps work on the principle of impeller resistance. The pump turns on every 2 1/2 minutes for about 1 second to sense for water. If water is present, the pump will sense resistance at the impeller and continue to run until water is removed. After that it will resume checking for water every 2 1/2 minutes. Water level is kept between 1/8” 3mm low and 3/8’ 10mm high.

Totally submersible pump with water cooled, ignition and TCO protected motor, stainless steel shaft and snap-on strainer base. These pumps are extremely efﬁcient, draw low current and offers high capacity output in a very compact housing, to ﬁt into the smallest available space. Please note – using the included check valve will reduce the output ﬂow of the pump. This pump cannot be run through a 240v transformer.
