Low Flow Toilets

Finding the best low flow toilets

The average household flushes about 35,000 gallons of water down the toilet every year. Your toilet is the number one indoor water consumer, typically accounting for more than a quarter of all usage. Given these facts, it's easy to see how low flow toilets have the potential to save you a lot of money on your annual water bill.

Low flow toilets, also known as low flush toilets, are available in a range of designs, but almost all of them use either pressure- or gravity-based technologies to assist in the clearing of the bowl. While early low flow toilet models were beset with leaks and problems, today's models are far more durable and efficient, with working parts that last longer and are more easily replaced if and when they break down.

Types of Low Flow Toilets

Stylistically speaking, there are countless low flow toilet designs available in a full range of colors. Some models have features that make your flushes sound like waterfalls or streaming brooks, but as a consumer, it's more important that you pay for quality than bells and whistles. Some trusted brands include Kohler low flow toilets, Sloan low flow toilets and American Standard low flow toilets, among others.

Like low flow showerheads, the primary feature of low flow toilets is reduced water usage. To qualify for the low flush toilet designation, a model must not use more than 1.6 gallons (6 liters) of water per flush; many of today's models use much less than this, thanks to improvements in the technologies used to evacuate the toilet bowl.

As mentioned, virtually all low flow toilets use either gravity- or pressure-assisted flushing to reduce water usage. Gravity low flush toilets release water from the tank when the flapper is pushed, using the momentum of gravity to drive the waste down the pipes. Pressure-assisted low flush toilets use small pockets of compressed air to give the waste water an added push; they are typically noisier and more expensive than gravity low flow toilets, but they are also considered stronger and longer-lasting, and their bowl evacuation technologies are more effective.

Many people feel the best low flow toilets are dual flush models, as these allow you to maximize your water savings. Dual flush toilets allow you to select one of two flush modes, each with varying water volumes, depending on whether you're flushing away liquid waste (which requires less water) or solid waste (which requires more).
