What are High-Efficiency Toilets?
High-Efficiency Toilets (HETs) use at least 20 percent less water than standard 1.6 gallon per flush (gpf) Ultra Low Flow Toilets.

In other words, HETs use 1.28 gpf or less on average.

There are three basic types of HETs:

• Gravity Flush Toilets – use the weight of the water to create a siphon action that pulls water and waste from the bowl.
• Pressure-Assist Toilets – have a sealed vessel inside the tank and use air pressure to force a flush.
• Dual Flush Toilets – allow you to select the amount of water that is used to flush the toilet, either a half flush for liquids or a full flush for solids.

Additional information about the performance and technology of these toilets is available at your local plumbing retailer.

Rebate Eligibility
