Keep your black and grey tanks odor-free and flowing freely. Lippert Flow Max is a 100% natural, formaldehyde-free holding tank treatment that neutralizes odors, breaks down waste and toilet paper, and keeps tank sensors reading accurately -- without harsh chemicals that harm campground septic systems or marina pump-out stations.
Holding tank odors get worse as temperatures climb. Many conventional treatments lose effectiveness above 80 deg F, letting sulfur and ammonia odors back into your rig. Lippert Flow Max is formulated to neutralize odors even in hot weather -- a critical advantage for summer camping and full-time RV living in warm climates.
The 64 oz bottle is a bulk-size value for full-timers, seasonal campers, or anyone who wants to keep a supply on hand without reordering every month. At typical dosing rates, one 64 oz bottle covers multiple tank treatments across the season.
Eliminates grey and black tank odors at the source rather than masking them with heavy fragrance. Effective even in high-heat conditions.
Enzyme and bacterial action breaks down solid waste and toilet paper quickly, reducing clogging risk and residue buildup at the tank outlet and valve.
Helps keep tank level sensors free of waste coating that causes false "full" readings -- a common frustration in black tanks.
100% natural, biodegradable, and formaldehyde-free. Safe for campground sewer hookups, marina pump-out stations, and municipal dump stations.
Most RV owners focus on black tank odor, but grey tanks -- fed by sink and shower drains -- accumulate grease, soap scum, and biofilm that create their own odor problems. Flow Max is formulated for both tank types, so one product handles your entire holding system.
Add Flow Max directly to the toilet bowl and flush into the black tank, or pour directly into grey tank drains. Use after every dump and tank rinse for best results. For heavy odor or sensor buildup, a double dose at the start of a trip helps break down residue faster.
Flow Max is also safe for use in marine holding tanks. Its biodegradable formula meets the environmental requirements of marina pump-out programs and is free of formaldehyde and other restricted compounds commonly banned at inland waterways.
