Environmentally Conscious 

At Lippert, we believe in using minimizing the footprint our products leave behind. That’s why we’ve made our RV tank chemicals in a 100% natural, formaldehyde-free formula that is environmentally friendly and biodegradable. This makes the Flow Max holding tank treatment safe to use at campgrounds, marinas and around the family. 

Instructions for Use 

Though your grey water tank doesn’t hold the amount of waste your black tank does, it can still begin to stink due to food residue, soap scum, grease, etc. To clean it, pour two ounces of this holding tank treatment into the tank, take a quick drive to slosh around the solution, drain it, then rinse using a flush valve. To treat your 40-gallon black water tank, pour two ounces of this treatment into your toilet bowl with one gallon of water. Flush the toilet and let the treatment work its magic! Be sure to store all bottles between 50°F (10°C) and 105°F (40°C). Please note: Temperatures above 85°F (29°C) will not require additional treatment. Temperatures below prolonged 40°F (4°C) may require additional treatment. Holding tanks should be emptied weekly, regardless of waste level.
