According to the US Environmental Protection Agency, the average family of four uses 400 gallons of water per day. About 70% of that water is used indoors. With so many places in the world experiencing record-breaking droughts, we all have a responsibility to do everything possible to conserve natural resources and reduce our water consumption.
Old toilets are notorious water guzzlers. They can use anything from 3.5 up to 7 gallons of water for a single flush. Newer toilets have a GPF rating – that is Gallons Per Flush. Federal plumbing standards in the US specify that new toilets must use a maximum of 1.6 gallons per flush and the latest high efficiency toilets use only 1.28 GPF or less. Installing a high efficiency toilet is not just a good bathroom remodel idea, it is a responsible decision. If we assume that a toilet is flushed an average of 5 times day, consider the difference a toilet can make.
TOILET WATER USAGE | GALLONS USED PER PERSON PER YEAR
7.0 GPF 12,775 1.6 GPF 2,920 1.28 GPF 2,336
What we think of as a conventional toilet is gravity fed. It has a tank that holds water, which pours via gravity into the bowl when flushed. The water then refills and stops when it reaches a certain height in the tank. Usual GPF is 1.6.
A dual flush toilet gives you the option of a short flush of 1.1 GPF for liquids and a longer one of 1.6 GPD for solids. The only problem with these toilets is that you have to remember to press the right button. They can end up using more water if you have to flush a second time to completely empty the bowl.
A pressure assisted toilet has an additional tank inside the main tank that contains pressurized air. The flush releases the pressurized air, which helps the water to remove the waste. These can be relatively noisy.
High efficiency toilets, or HETS, are the latest toilet innovations that can use as little as 1.1 GPF, while still providing equal or superior performance.
THE WATERSENSE LABEL
The WaterSense label was introduced by the US Environmental Protection Agency to distinguish products that are water efficient. The label is used on toilets that are independently certified to meet rigorous criteria for both performance and efficiency.
The WaterSense label tells you that the products:
- Perform as well or better than their less efficient counterparts
- Are 20 percent more water efficient than average products in that category
- Realize water savings on a national level
- Provide measurable water savings results
- Achieve water efficiency through several technology options
- Obtain independent, third-party certification
By replacing just one older toilet with a high efficiency version, you can instantly cut down water usage, help the environment and reduce your water bill. This is a bathroom remodel idea that has got to be a win – win situation.
