Before 1994, most toilet models used at least 3.5 gallons of water per flush. All new models today are “low-flow” and use no more than 1.6 gallons.

There are two basic kinds of toilets.

Gravity-flush toilets, which is the conventional ones for residential use and are less expensive and easier to maintain.

The other kind is pressure-assist toilets, which is best suited for commercial use. They are generally more effective in removing solid wastes.

Low-flow toilets not only save you on water bills, but also save the average U.S. household more than 9000 gallons of clean water per year.

But not all low-flow models on the market work well. To choose a well-functioning toilet, check the performance ratings tested by Veritec Consulting Co.

Veritec Consulting was founded by Bill Gauley, an engineer. Toilets that tested in the Veritec test lab all face the same technical challenge.

The company publishes performance results several times a year and it has helped revolutionize the toilet industry.

So check the Veritec Consulting ratings before you decide on purchasing a toilet. A low-flow toilet that works well will save you money and help conserve water.
