Bilge Pumps
Bilge Pumps/Float Switches
All bilge pumps fitted to your Sealine have float switches. In the case of the forward and aft bilge pumps this is for
safety reasons. Should a leak occur when the vessel is unattended these float switches have a permanent source
of power from the push to reset circuit breakers fitted in the battery isolation panel in the cockpit locker (see System
Control Points Diagram).
In the interest of safety, the operation of the float switches on these pumps should be checked from time to time to
ensure that they operate smoothly. An occasional check should be made on the condition of the bilge pump
strainer; this should be kept clear of debris and other foreign matter.
The pump itself is not affected by freezing temperatures.
The instructions below will help you obtain the maximum output and life from your pump: -
Symptom Possible Cause Cure
Repeatedly
tripping
circuit
breaker Faulty wiring
CONSULT QUALIFIED ELECTRICIAN
Reduced
Flow
Blocked
strainer
Clean out side of strainer and clean debris from around impeller
Discharge line
blocked with
trash
Clean out hose by back flushing
Low battery
voltage Check battery condition and charge if necessary
Kinked
discharge hose
Repair or replace hose
No water
pumped Wire
connections
Make sure wire connections are not corroded. Visual check is not enough - a slight pull on each wire should
tell if the wires are still joined. Check to be sure no wire joints are hanging down into the water
Tripped
breaker
Reset circuit breaker. If breaker still blows, check impeller through inlet opening to be sure it is not jammed
or stuck with debris
Float switch
failure Lift end of float switch up - if pump runs, switch is OK. If pump does not run, turn Manual Switch to ON
position - if pump runs, automatic switch has failed
Pump won’t
shut off
Something
under float
Clean under float to make sure that debris is not holding the float up
Stuck float
Check to see that the float is loose and free of gummy oil. If float action appears sluggish and/or the float
does not move freely, intermittent or sporadic operation of the pump may occur. This condition is usually the
result of oil and/or dirt accumulating in and around the movable parts of the switch. To correct try soaking
the entire switch in the bilge cleaner for ten minutes agitating several times and checking for smooth and
free operation of the float. Repeat if necessary.
Switch
mounted to low
If the pump is sucking air and the automatic switch has not reached the OFF position, then the switch may
be mounted too low for the pump and should be re-installed higher than the pump base.
Shower Sump
The only maintenance required on the sump system is to drain the unit during the winter months when not in use.
To drain; disconnect and drain all lines to the unit. Remove hold down screws and empty the unit. In some
installations it may be impossible to completely drain the system. As a result of this it is recommended that non-
toxic RV/Marine antifreeze be added to the shower drain and circulated throughout the system. Periodic cleaning of
the filter for improved performance is recommended. Ensure the cover gasket is in place when reinstalling the filter
and cover.
