What Are Vacuflush Toilets?

VacuFlush toilets are a proprietary marine toilet system manufactured by SeaLand. Used on boats because the VacuFlush reduces the amount of water used in each flush cycle, the system looks and operates similar to a conventional toilet. But it is powered by the standard 12- or 24-volt direct current found on boats.


The VacuFlush consists of components attached to the waste-water holding tank. The vacuum pump creates a vacuum held in a tank until the toilet is flushed, commonly by pushing a foot pedal. The vacuum draws water and waste into the waste-water storage tank. The vacuum moves the waste more efficiently, requires less water and therefore places less material in the waste-water tank than standard marine heads that move waste by water pressure.


The VacuFlush is electrically operated, drawing less than 6 amps of electricity and producing less drain on the boat's battery or electrical system than other systems. Using a supply of fresh water to operate the VacuFlush reduces odor and keeps the toilet cleaner.


Each flush of the VacuFlush uses less than a half liter of water. This increases the number of flushes that the holding tank can accommodate between cleanings. This allows the boat to stay at sea or in operation longer. By using less fresh water for each flush, the system reduces the costs associated with purifying water. The VacuFlush features simple one-push pedal operation, allowing even landlubbers the ability to flush the toilet. The optional control panel indicates when the vacuum has recharged. The ease of use and efficiency the VacuFlush may increase the resale value of a boat.


VacuFlush toilets are available in low-standard or medium-height configurations. In addition, the toilet can discharge through the floor or wall depending on plumbing placement on the boat.
