Keep your black and grey holding tanks odor-free, clog-free, and sensor-accurate with Lippert Flow Max. This 100% natural, formaldehyde-free liquid treatment is safe for all campground and marina dump stations and works in RVs and boats alike.
Holding tank odors are one of the most complained-about parts of RV living, and they get worse in summer heat. Lippert Flow Max uses a 100% natural formula to neutralize odors at the source -- not just mask them -- while actively breaking down solid waste and toilet paper so your tank empties cleanly at every dump.
Unlike older formaldehyde-based treatments, Flow Max is biodegradable and safe for septic systems, campground dump stations, and marina pump-out stations. You get effective treatment without chemical harm to infrastructure or the environment.
Eliminates grey and black tank odors even in high heat. Works on contact and stays effective between dump cycles.
Breaks down solid waste and toilet paper to prevent clogging and residue buildup that can restrict tank sensors and outlet valves.
Keeps holding tank level sensors clean and accurate so your monitor panel gives reliable readings throughout your trip.
100% natural, biodegradable, and formaldehyde-free. Safe for dump stations, campgrounds, and marinas without restrictions.
Flow Max is designed for both black water (toilet) tanks and grey water (sink and shower drain) tanks in RVs, travel trailers, fifth wheels, motorhomes, and boats. Add it directly to the toilet bowl or drain before use so it coats the tank walls and begins working immediately.
Traditional holding tank treatments containing formaldehyde are banned or restricted at many state parks and campgrounds due to environmental impact on sewage processing systems. Flow Max contains no formaldehyde, making it universally accepted at campgrounds and marinas across the USA. You don't have to check signs at each dump station before treatment.
Pour the recommended amount of Flow Max directly into the toilet bowl and flush, or pour into a grey tank drain. The liquid coats tank walls and goes to work immediately. Reapply at the start of each trip or after each dump as part of a regular maintenance routine.
