The History of Low Flow Toilets - Angola Transparency

The flush toilet was not invented by Thomas Crapper, as is commonly believed. Englishman Joseph Adamson’s 1853 design, known as the siphon flush, was the first toilet that prevented sewer gases from entering the home. This design eventually made chamber pots and outhouses obsolete. Modern toilets, including low flow toilets, rely on the movement of liquid to create a flush.

Key Facts

U.S. law: Since 1992, U.S. law has mandated that all new toilets sold in the United States use 1.6 gallons (6 liters) or less per flush.
Water consumption: Low flow toilets are high-efficiency toilets that reduce water consumption per flush. They help save water and money in your home.

Evolution of low flow toilets: The first generation of low flow toilets, introduced in 1994, often required two flushes to effectively clear the bowl. Manufacturers addressed this issue by modifying the passageways to move a reduced amount of water more vigorously into the bowl.

The Benefits of Low Flow Toilets

Low flow toilets have several benefits, including:

Water conservation: Low flow toilets use less water per flush than traditional toilets, which can save money on water bills and help to conserve water resources.
Lower energy costs: Low flow toilets use less energy to operate than traditional toilets, which can save money on energy bills.
Improved hygiene: Low flow toilets are more hygienic than traditional toilets because they use less water to flush away waste, which can help to prevent the spread of bacteria.

The Drawbacks of Low Flow Toilets

There are also some drawbacks to low flow toilets, including:

Clogging: Low flow toilets can be more prone to clogging than traditional toilets, especially if they are not properly maintained.
Inadequate flushing: Some low flow toilets may not have enough water to adequately flush away waste, which can lead to unpleasant odors and unsanitary conditions.
Higher cost: Low flow toilets can be more expensive than traditional toilets, although the cost difference is typically offset by the savings on water and energy bills.

Conclusion

Low flow toilets are a water-saving alternative to traditional toilets. They have several benefits, including water conservation, lower energy costs, and improved hygiene. However, they also have some drawbacks, such as clogging, inadequate flushing, and higher cost. When choosing a low flow toilet, it is important to consider the pros and cons carefully to make sure that it is the right choice for your needs.

What are some of the latest innovations in low flow toilets?

Some of the latest innovations in low flow toilets include:

Dual-flush toilets: Dual-flush toilets have two buttons, one for a full flush and one for a half flush. This allows you to use less water for liquid waste.
Pressure-assist toilets: Pressure-assist toilets use compressed air to help flush the toilet. This can help to improve the flush performance of low flow toilets.
Tankless toilets: Tankless toilets do not have a tank. Instead, they use a small reservoir of water to flush the toilet. This can save space and water.
