What type of pump is typically used for flushing a toilet?

A diaphragm pump is commonly used for flushing a toilet due to its ability to create a strong pressure differential, which is essential for effectively moving water and waste. This type of pump utilizes a flexible diaphragm that moves back and forth, creating suction and discharge cycles that can efficiently manage the flow of liquids. The design of diaphragm pumps allows them to handle both clean and dirty water, making them suitable for various applications, including marine toilets where sanitation and reliability are critical.

Diaphragm pumps also offer advantages such as self-priming capability, resistance to clogs from solids or debris, and the ability to operate in a variety of orientations. This makes them ideal for use in the compact and often constrained engine compartments of boats or other marine vessels. Their robust construction and performance make diaphragm pumps the preferred choice in systems requiring reliable pumping for flushing toilets, helping to maintain hygiene and functionality in marine applications.
