1What's the difference between raw water and fresh water plumbing systems on boats?

Raw water systems pull directly from the sea or lake and need corrosion-resistant materials like bronze or stainless steel, while fresh water systems use potable water stored in tanks and can handle standard plumbing materials. Raw water is typically used for cooling engines and deck washdowns, whereas fresh water serves galleys and heads.

2How do I know what size water tank I need for my boat?

Calculate based on your crew size and trip length—a rough guide is 1 gallon per person per day for drinking and cooking, plus extra for washing. For a week-long trip with 4 people, you'd want at least 30-40 gallons, though larger cruising boats often carry 50+ gallons.

3Should I choose flexible hose or rigid piping for boat plumbing?

Flexible marine-grade hose is easier to install in tight spaces and handles vibration better, while rigid PVC or metal piping takes up less room and lasts longer without degradation. Most boats use a combination—flexible hose for connections and rigid piping for main runs where space allows.

4What materials should I avoid for saltwater boat plumbing?

Avoid standard copper, brass, and galvanized steel as they corrode quickly in saltwater; instead use bronze, stainless steel, or marine-grade plastics. Even hoses must be labeled as marine-grade to resist salt water's corrosive effects over time.

5Is it worth upgrading to a macerator toilet instead of a standard manual head?

A macerator grinds waste and pumps it directly overboard, saving tank space and pump-out trips, but it requires electricity and is more complex to repair. Choose it if you take long trips or want convenience; stick with manual or traditional holding tanks if you prefer simplicity and don't mind frequent pump-outs.
