Find Which Flush Best Fits Your Needs

Heather Asiyanbi - 7/23/18 11:48 AM

Toilets have moved from a utilitarian necessity without any real style to an integral piece of your bathroom design. Toilets have undergone other changes over the years as well; touchless operation, bidet integration and the introduction of smart home tech, for example, but what hasn't changed is the need for good flushing. Your toilet must effectively and efficiently swish waste away at the same time it looks great.  

Toilet flush systems have evolved over time. Just a few years ago, toilets used up to 3.4 gallons of water per flush. Water-saving requirements in several states like California pushed manufacturers to create toilets that require significantly less water; a maximum of 1.6 gallons per flush.

Single Flush

Toilets traditionally have only come with one way to, and kind of, flush; the all-or-nothing gravity-fed (siphonic) system. You push down on the lever, and the flapper inside the tank flips open, releasing water into the bowl and creating a siphon so waste is pulled into the trap from the bowl.  

While the mechanics of a gravity-fed toilet haven't changed much over the years, manufacturers have found ways to improve the parts to create stronger flushes, so you can take care of some of life's most important tasks with confidence.

Dual Flush

Gravity-fed toilets are also available in a dual-flush option as well. Instead of using 1.6 gallons of water per flush every time, you'll have the choice of .8 gallons for liquid waste and the maximum for solid waste. Dual-flush toilets increase water savings and lower your water bill.

Canister Flush

Proprietary to Kohler under the AquaPiston name, a canister replaces the traditional flapper with a larger valve opening. When you push the toilet lever, the canister is lifted up, and water flows into the bowl from multiple directions so waste is pushed into the trap. The valve opening on a canister-flush toilet is bigger than a gravity-fed - 3-1/4 inches compared to three inches - which means you'll experience a more powerful flush.

Pressure Assist

You'll find a pressure-assisted toilet most often in public restrooms, but there are some available for homeowners. Toilets with pressure-assist flushing utilize a pressure tank inside the porcelain tank that fills up with water and holds it there. The pressure builds until the valve opens, and the combination of pressure and gravity creates the most powerful flush available.

While a pressure-assist toilet can give you more confidence because it will rarely, if ever, clog, it is noisier than either a gravity-fed or a canister flush toilet. 

The bottom line is that you will save water and money with the toilets that are available on the market because the maximum amount of water you'll use is just 1.6 gallons of water per flush no matter if you choose a single, duel, pressure assist or canister flush. Even better? Toilets today are designed to fit in perfectly no matter your style and overall design scheme.
