Considering a Dual Flush Toilet? Study Up Before Taking the Plunge

Considering a Dual Flush Toilet? Study Up Before Taking the Plunge

Georgia’s toilet standards are among the nation’s strictest, but the driving force behind them is smart water conservation. Older toilets, which waste anywhere between three and five gallons per flush, contribute to local water shortages and put a strain on the community.

Today, new toilets in Georgia have the standard of 1.28 gallons per flush - and this has made the dual flush toilet popular. Are these systems right for your home? Here’s what you should know before taking the plunge.

The Science of the Dual Flush System

The term “dual flush” refers to the two options that come on this toilet type. In the first option, users select the button or lever for a lighter flush - typically from 0.9 to 1.1 gpf. This option is ideal for urination. The second option would activate the full-volume flush - 1.28 gpf - to handle solid waste.

Comparing the highest volume of 1.28 gallons of water to the old standards of three-to-five gallons, you might think there isn’t enough water to do the job right. However, a dual flush toilet uses a superior siphoning system and water flow to handle the same amount of waste with less water.

Saving Water Without Sacrificing Comfort

The latest dual flush models don’t force you to sacrifice comfort for improved water consumption. Higher seats and improved water flow deliver a better overall experience and the same performance as the lower, water-wasting models of the past.

Assuming a household of three people at five flushes per day per person, a 3.5-gpf toilet will use about 20,000 gallons of water per year. A 1.28-gpf toilet would use about 7,000 gallons of water on that same operation, assuming a full flush. Taking it down to 0.9 or 1.1 gpf for the partial flush option, the savings is even greater. Imagine saving 15,000 gallons of water by simply switching toilets.

As a Casteel blog recently pointed out, green initiatives often make as much sense for wallets as they do for community resources. There may be a time when the dual flush toilet becomes standard. For now, you can save on utility bills while doing your part for the community when you switch. Ask Casteel’s pro plumbing team about your options and how to get started.
