Marine Plumbing & Ventilation — frequently asked
- How do I size a bilge pump?
- Bilge pumps are rated in gallons per hour (GPH), but actual output is lower once you account for hose length and vertical lift. Choose a pump rated well above your expected worst-case water intrusion, and consider a second, higher-capacity pump plus a float switch for automatic operation.
- Can I use regular garden hose for my boat’s water system?
- No. Marine plumbing uses purpose-built hose rated for the specific system — potable water, sanitation, and raw-water/bilge hoses differ in pressure rating, temperature resistance, and permeation. Using the wrong hose causes odors, leaks, or contamination.
- Why is ventilation important on a boat?
- Ventilation clears moisture that causes mildew and rot, and — critically on gasoline boats — clears fuel vapors from the engine compartment before starting. Blowers, cowl vents, and dorade boxes keep air moving through cabin and engine spaces for safety and comfort.
