Frequently Asked Questions

Selecting the right toilet for your boat can be a daunting task. Here are some frequently asked questions to help you with your concerns. Review these topics for more information on the things to look for and consider when buying a marine toilet.

How Does Marine Toilet Work?

A marine toilet is designed to accumulate waste in a holding tank on board until it can be pumped out into an onshore waste-disposal facility. Many marine toilets have a hand pump that allow you to use water directly from the sea or lake for flushing the toilet. 

How To Install Marine Toilet?

The installation of a marine toilet must abide by all coastal and inland regulations. In other words, you cannot directly discharge untreated sewage into the water which means you must be sure your head discharge hose is connected directly to a holding tank.

How To Flush Marine Toilet?

Some marine boats have a hand pump that require you to pump water into the bowl in order to rinse away the waste. Other toilets have a foot pedal to fill the bowl with water prior to using it. You then open a slide valve to dispose of the waste.

How To Unclog Marine Toilet?

Avoid using strong chemicals to unclog the drain in your marine toilet. You can try pouring a small amount of vinegar into the bowl and then use a plunger to try to break the clog-free. Most clogs are in the outlet hose which means you may need to disassemble it in order to clean it out.

Conclusion

You have many options available when it comes to choosing a marine toilet. Your choice should be based on the size of your boat and whether it needs to be a semi-permanent installation. Be sure you know the regulations of your destination locations when it comes to proper waste management and disposal!
