Water Saving Toilets Under 1.6 GPF (Complete Guide)

Water is one of the earth’s scarce resources, and as populations grow, there will be increasing pressure placed on these resources. Water remains the most effective means of flushing waste down a modern toilet. Governments are putting pressure on manufacturers to reduce the amount of water used in the toilets that they produce, and they have responded with new and more efficient flushing technology, while still managing to reduce the volume of water required. We’ve reviewed some of these toilets below. As pressure mounts to reduce water consumption, governments will respond by increasing taxes or prices per gallon. For the buyer who is looking for a replacement toilet, a new water-efficient toilet may be worth considering.

This two-piece toilet is the lowest priced unit in this category, and given its powerful flushing system, it is very good value for money. It has a high-profile tank and an elongated bowl constructed from vitreous china. It is available in white.

The flush is activated by a top-mounted push button. It has a pressure-assisted flush, which is why it can clean the toilet using only 0.8 gallons of water per flush (GPF). To create this powerful and water-efficient flush, the water in the tank is held under pressure. When the toilet is flushed the flush valve opens, and the combination of gravity and pressure results in a powerful flush. The Seat is not included.

The rim is pressurized and once flushed, the water is propelled from the rim. At the same time, the waste is pulled out of the bowl by the siphon. The seat is not included, but two color-matched bolt tops are. American Standard offers the longest warranty in the industry. This product has a limited lifetime warranty on china parts and a limited five-year warranty on the mechanical components.
