CLEANING – HOLDING TANK

A small amount of water remains in all holding tanks. It is good practice to rinse the tank after the contents have been discharged. This can be accomplished by adding water to the toilet bowl. Add 237 ml (8 oz.) of SeaLand® Holding Tank Deodorant to the bowl. Flush the entire contents into the holding tank and continue flushing until the discharge from the holding tank is clear.

Do not use chlorine-based cleaners, caustic cleaners or chemicals, such as drain-opening products, as they may damage the system’s seals and hose.
