Extra Heavy-Duty #148 Marine Sanitation Hose
Sanitation hose must handle sewage from the toilet to holding tank, through pump-out and vent deck fittings and discharge thru-hull fittings (where legal). Failure or odor permeation is very unpleasant, so select and install your hose carefully. Choose hose that is labeled "Sanitation." It should be made of smooth (inside and out), heavy-wall, flexible, and odor-resistant construction and formulation. Good installations are short and self-draining (no kinks, loops or dips) with tight connections.
This extra-heavy-duty sanitation hose of smooth white vinyl is specially compounded to provide excellent resistance to odor permeation and FDA-approved potable water fill. Hard PVC helix gives good flexibility and bend radius.
