How is the bilge pump typically tested?

The proper method to test a bilge pump involves using the manual load, which ensures that the pump is functioning correctly under the actual conditions it will encounter while in operation. This method allows for a thorough assessment of the pump's performance, including its ability to move water effectively from the bilge area. During this testing process, the pump is activated with a specified load to simulate the conditions it would face in real scenarios, confirming that it can handle the anticipated volume of water.

Visual inspection alone does not assess the pump's operational capabilities or performance under load. Continuous operation may lead to overheating or failure if the pump is not designed to run indefinitely, which could result in misleading tests regarding its performance. Measuring the water level, while important for determining the necessity of pumping, does not provide direct feedback on the pump's functionality. Thus, using the manual load is the most reliable way to ensure the bilge pump meets the required operational standards.
