When the federal government mandated that new toilets use no more than 1.6 gallons per flush, manufacturers had to develop a toilet that would achieve this but that would also flush properly (clear the bowl) and carry the waste to the city sewer or septic system. Some of the early models did not do this properly. Since then, the complaints have forced the manufacturers to develop new ways of flushing toilets. One new way is the use of a pressurized toilet tank. This model looks like a regular toilet, but it has a pressure tank inside. When flushed, it works like a commercial toilet. A large surge of water enters the bowl and clears it of any waste. These toilets work well, but are not as quiet as a conventional models, but do eliminate the common toilet problems associated with the early 1.6-gallon models.
When considering a new fixture for your home, such as a toilet, we recommend that you choose a fixture made by one of the major manufacturers, such as American Standard, Kohler or Eljer.
