System Design {[pictures of various fittings]}

Think your system design through carefully and lay out piping and other system components before cutting anything. Check on each side of partitions or bulkheads to be sure you will not be cutting into fuel or water tanks, wiring or piping, or into stringers that support the hull. If you must cut tabbing that holds bulkheads or partitions in place, provide additional reinforcement so that structural integrity is not compromised.

To reduce likelihood of odor permeation, consider what will be "wet" (sewage filled) between pumpouts. Work toward reducing wet sections of piping. When wet sections are unavoidable, consider rigid PVC pipe rather than hose. Keep the number of connections to the minimum. Try to eliminate tight bends; use "sweeps" to minimize clogging. Provide for easy access to system fittings, connections, and components for maintenance. {[Illustration of how to cut for you piping.]}

Toilets

• Install per manufacture's directions.
• Electrical wiring (if any) should comply with ABYC standards E-8, AC Electrical Systems in Boats, and E-9, DC Electrical Systems Under 50 Volts.
• Freshwater hookups must comply with ABYC standard H-23, Installation of Portable Water Systems, which requires physical separation of drinking water from the sewage system.
