    High Efficiency Toilets (HETs)

    HETs were designed to conserve water. According to the Environmental Protection Agency (EPA) toilets which use 20% less water per flush then the standard 1.6 gpm are considered HETs. There are various types of HETs: Single or Gravity Flush Toilets, Dual-Flush Toilets, Pressure-Assist Toilets and Power Assist Toilets.

    Dual-Flush Toilets operate with a handle that can move up or down, or two buttons. One direction or button activates the lower volume flow flush, while the other activates the higher volume flow flush. The lower volume flow flush capacity on Dual-flush toilets typically range from .8 to 1.1 gallons per flush, whereas the higher volume flow flush capacity ranges from 1.3 to 1.6 gallons per flush. We've found the dual-flush toilets work well in environments where users are conscious of conservation and understand the advantages of using the low versus the high flow flush.

    Pressure Assist Toilets use either water pressure or a device in the tank to create additional force from air pressure to flush the toilet. They typically average 1.1 to 1.2 gallons per flush. Some pressure assist toilets move a greater volume of water, but a trade-off may be a higher volume of sound.

    Power Assist Toilets use a pump or air to force water down at a higher velocity than gravity feed toilets. are the newest invention to hit the market. Some Power Assist Toilets require a 120V power source to operate the small pump. One of the newest Power Assist toilets on the market is Niagara Stealth and uses air pressure. Typical flush volumes for Power Assist Toilets range between .8 and 1.3 gallons per flush and are typically quieter than the Pressure Assist Toilet

  • How do I measure to determine the rough-in for a toilet?
  • To measure the rough-in for a toilet, measure from wall behind the toilet to the center of the toilet floor drain. The typical rough-in for a toilet is 12", however; some older homes have a 10" rough-in.
