My electric bilge pump is running but not pumping water. After
searching the archives I have concluded that I need to take the pump
portion appart in order to clean and possible replace the pump valves.
Do I need to remove the whole mechanisim from the bulkhead and service
the pump on a workbench or can the work be done by removing the
plate/cover and working on the pump valves and diaphram while it is
still bolted to the bulkhead?
