Flushing System

Kohler’s class 5 toilets are renown for the amount of waste that they can flush away in a single flush, even with only 1.28 gallons of water. The dual flush system delivers a full flush of 1.28 gallons or a partial flush of 1.1 gallons.

This video, from Kohler, explains the way that the flushing system works.

Cleaning

On a full 1.28 gallon flush, this toilet will clear up to four times the volume of waste that the average adult needs. This efficiency in clearing waste is due to a combination of the siphon action giving additional power to the water entering the bowl, the way that the water enters the bowl around the full circumference of the rim, and the design and shape of the toilet bowl.

 

Consumption

This toilet has a dual flush delivering either 1.28 gallons of water per full flush or 1.1 gallons on a partial flush. The toilet, due to its low water consumption plus the ability of the toilet to clear all waste in a single flush is what make the toilet EPA Water Sense certified. Water Sense certified toilets can, in many areas, qualify for rebates from water bills. To check if your area is covered check out the EPA Water Sense rebate finder page.

 

Ease of Installation

The toilet uses a standard rough in of 12” to the center of the waste pipe from the wall. To install the toilet you need to have a new trap seal, new T-bolts (and nuts) if your existing ones are corroded and a toilet seat. To function correctly, the bowl needs to be level. The level of the bowl can be adjusted by tightening the three mounting bolt incrementally until the level is achieved.
