Best Dual Flush Toilet

Dual flush toilets are a great toilet system to have in your home, allowing you to control how much water you use per flush.

Dual flushes work by either triggering a full flush which would be required for heavy waste or a half flush for lighter waste.

Toilets use a lot of water so having the ability to minimize consumption through a dual flush option is increasing in popularity.

The following post will explore the best dual flush toilets on the market.

Low Consumption EPA certified Toilets

EPA has a specific program or certification that they use to provide a water sense approval.

Toilets that are EPA approved consume 80% less water than the federally regulated 1.6 gpf (gallons per flush).

It is fair to be concerned about the quality and power behind a flush that uses a lower rate of water.

To gain the EPA certification the toilet still must pass the miso paste test, meaning it must clear miso paste on the bowl in a single flush.

The toilets reviewed in this article all have the EPA water sense certification aside rom the Saniflo Sanicompact.

This is because this toilet is a macerating or upflush toilet that has it’s own pump to remove waste.

This toilet is still a low water consumption toilet and it does have a dual flush.
