Testing Bilge Pumps
•
The bilge pumps and autofloat switches are vital to the safety of your yacht.
•
As described below, test the bilge pumps and autofloat switches often.
1. One at a time, turn
On
the bilge pump switches at the helm.
2. Make sure that water in the bilge is pumped overboard.
If there is water in the bilge and a pump motor is running, but
not
pumping, inspect the discharge hose for a kink or
collapsed area.
If the discharge hose looks okay, the bilge pump and/or strainer may be clogged with debris. Go to the websites
below for cleaning and maintenance instructions:

Testing Autofloat Switches
•
The autofloat switches turn
On
the bilge pumps when bilge water rises above a preset level.
•
The autofloat switches are either built into or located next to the bilge pumps they control.
•
Test the autofloat switches often as follows:
Lift the float by twisting the test knob. The bilge pump should turn
On
.
•
If the pump does not turn
On
, check the fuse on the 24-hour-load fuse block.
•
If the fuse is good it may mean the switch is bad, or the battery is dead.
