    Many different types of toilets use different amounts of water each flush. Below is a list of the amount of water needed for some:
    1 gallon per flush = urinal
    1.2 gallons per flush = high efficiency
    1.6 gallons per flush = low flow (mandated in California post-1992)
    3.6 gallons per flush = high flow
    anything higher = yikes
