A marine sanitation device (MSD) is very useful for any voyage of any duration, and it is essential for any vessel going in inland waterways with an installed toilet. Raw sewage is treated in certain MSDs so that it can be discharged straight from the vessel without damaging the environment. Certain states, however, have strict no-discharge zones (typically where there is no navigable outlet to the sea), so check the laws with the local Coast Guard or regulatory office before embarking on your journey.

The sanitation hose is an essential component of any MSD

When establishing a new system, there are numerous options to consider, and this page examines some of the different hosing options and their unique attributes. It’s critical to select hosing depending on your specific requirements; there is no one-size-fits-all solution. Make sure that whatever hosing you choose says “Sanitation” on it.

Sanitation hosing is used for a variety of reasons. It must successfully transport sewage from the toilet to the holding tank, from the holding tank to the pump out point, and from the pump out point to any vents. Clearly, odor permeation is a bad thing, so carefully consider your options to see which one will work best in your situation. Furthermore, regardless of which hosing you choose, a poor installation will invalidate its advantages. The line must be free of kinks, loops, and dips, and all connections must be secure. Alcohols, antifreeze, petrochemicals, and solvents should not be used in sanitation hosing unless properly labelled. Before it breaks down, all hosing has a maximum operating temperature (for both hot and cold climates). Pay special attention to this aspect if you’re in an area with extreme weather.

The Shields Sanitation Hose includes an EPDM tube and cover, as well as two fabric plies and is wire reinforced. This results in a hose that is both kink-resistant and extremely flexible. It withstands ozone, salinity, and heat and is resistant to toilet chemicals. It’s ideal for connecting the toilet to the holding tank, as well as the holding tank to the pump out point. It has a high level of resistance to odor permeation.

The Shields Vac Extra Heavy Duty/Commercial Grade Hose is used for hookups below the waterline.

There are two excellent choices for pressurized water system supplies (hot and cold), as well as wash down hoses for pump networks and head intakes.
