Learn about Wall-hung Dual Flush Toilet

Wall-hung Dual flush toilets have two options for flushing; a low volume flush for liquid waste, and high volume flush for solid waste. New dual flush toilets have effective, efficient water volumes for both low and high flush, making their average flushing volume low enough to meet high-efficiency or ultra-high efficiency standards. A wall-hung version means the water tank is concealed behind the wall, providing significant modern appeal, along with easier cleaning.

Federal guidelines in both Canada and the USA specify that new toilets must meet the standard of a maximum of 6L (1.6 gallons) per flush. The US EPA Watersense labeled toilets have a maximum of 4.8 L (1.28 gallons) per flush. They also must flush at a minimum 350g of waste per flush. These toilets are also called High-Efficiency Toilets (HET). Dual-flush toilets often meet these same standards too and give you the chance to save even more by choosing which flush button to use.

The Maximum Performace (MaP) Testing Program, which was developed in partnership with the Canadian Mortgage and Housing Corporation (CMHC) and the Canadian Water and Wastewater Association (CWWA). The MaP initiative tests toilets under realistic conditions and grades them based on overall performance. You can search forthe grades for different toilets.

A dual-flush, high-efficiency toilet saves a tremendous amount of water, compared with previous toilets that used 10 to 18 litres (3 to 5 gallons) per flush. Toilets are the single largest water user in a household, accounting for up to 30% of household water use, so installing a more efficient toilet is your best way to reduce your water consumption. With dual-flush, you can choose to save water on each flush by using the low-volume or high-volume flush button.

The ancient city of Harrappa, part of the Indus Valley Civilization in what is now India, had an early version of flush toilets in many of the houses, over 4,000 years ago!
