Decided to test bilge pump by using the garden hose to place water in the bilge. When the pump got submerged I heard it turn on (made a noise) however it did not pump any water. Also tried manually turning it on with the toggle which did not make a difference. After draining water through the plug the pump turned off. Is my bilge pump not functioning properly? should water start coming through the hull once the pump cuts in? My guess is its not pumping even though it makes a noise. Any other suggestions is greatly appreciated.
