Plumbing equipment for boats is essential for maintaining a clean and functional water system on board. Key components include freshwater tanks, which store potable water for drinking, cooking, and cleaning, along with pumps that distribute water throughout the boat. Marine toilets (also called heads) and holding tanks manage wastewater, ensuring proper sanitation while complying with environmental regulations. Bilge pumps help remove excess water from the boat’s lower areas, preventing flooding and maintaining buoyancy. Additionally, water heaters provide hot water for showers and sinks, while filtration systems help purify water for safe consumption. Proper maintenance and regular inspections of the plumbing system are crucial to prevent leaks and ensure smooth operation while at sea.
