Expensive breakdowns commonly occur when the marina's sewer line gets clogged because of inadequate rinsing. Flushing water through the system is cheap preventative maintenance and helps prevent odor. Use environmentally compatible holding tank deodorants. Pumpout only your holding tank. Pumpouts are not designed to handle bilge water or solid objects.
Some boaters pump out their holding tanks and then drive off, leaving the unit still running.
Make sure the pump is off before pulling away so it will work for the next boater. Don't forget to wash your hands when you are done. Consider using a mobile pumpout service if you don't want to service the holding tank yourself.
