What's the difference between a deluxe and a flushing unit?

A flushing unit is a deluxe unit with an integrated fresh water tank and waste tank that operates more like a permanent toilet, while a deluxe unit typically has a flushing mechanism but uses the same single holding tank as a standard unit. The flushing unit's separate tanks and pressurized flush provide a noticeably cleaner experience for guests. It stays cleaner and smells less because each flush introduces a small amount of clean water, which helps rinse the bowl and seal the waste in the separate holding tank, reducing odor. A deluxe unit with a flush still uses the single-tank system, so waste remains in the bowl area until the next service, which can lead to more noticeable odor, especially in warm weather. For your 140-guest, five-hour wedding with alcohol, the flushing unit's performance is superior. The guideline for events is about one unit per 50 to 75 people for four hours, and you need more for a longer event with alcohol. Your plan for a cluster with an ADA-compliant unit meets the ADA 5 percent cluster rule. The flushing unit costs more because it has a more complex system with two tanks and a pump. Both units require a service visit from a vacuum truck, but the flushing unit's design offers better hygiene for a formal event.
