Not only is water conservation important to the environment, but it can also help save you money on your water bill each month. Standard toilets now flush at a rate of 1.6 gallons per flush (gpf) – which is less than 50% of the water used by older 3.5 gpf toilets.
Flush Facts
Design improvements have allowed toilets to use 1.28 gallons per flush or less while still providing equal or superior performance. This is 20 percent less water than the current federal standard of 1.6 gallons per flush.
The current federal standard for toilets is 1.6 gallons per flush. This federal standard passed in 1992, so if your toilet was installed before 1992, it most likely uses 3.5 GPF to 7 GPF.
1.6 Gallons Per Flush ( gpf ) is a little over one and a half gallons ( 6 quarts ) of water and 1.28 gpf is a little more than 1 and a quarter gallons of water (5 quarts ) per flush. So if you're looking to save water, which I highly recommend, the 1.28 gpf is the way to go.
2006-2007: The WaterSense program launches, issuing high-efficiency specifications for toilets. Tank-type toiles must be independently certified to use 1.28 GPF or less, and remove at least 350 grams (12.3 ounces) of solid waste per flush, illustrated as a pass/fail test.
Special Note: If your toilet tank has a large black cylinder inside, rather than the standard flush mechanism, your toilet's maximum flush volume is 1.6 gpf or less. The flush volume is usually printed on the cylinder.
When the federal government mandated that new toilets use no more than 1.6 gallons per flush, manufacturers had to develop a toilet that would achieve this but that would also flush properly (clear the bowl) and carry the waste to the city sewer or septic system. Some of the early models did not do this properly.
But, the rule of thumb is to replace your toilet every 25 years, due to damage and regular wear and tear. If you have an older toilet, you should consider newer model toilets as they will be more efficient in conserving water and utility costs.
Pressure-assisted toilets offer even more flushing power than gravity or dual-flush. “A pressure-assist toilet has additional pressure that will give you a more powerful flush, which is more resistant to clogs, uses less water, and can be easier to clean,” says Hicks.
A toilet will normally use about 2-3 gallons per minute (gpm), a shower from 1.5 to 3.0 gpm, a bathroom or kitchen faucet from 2-3 gpm, a dishwasher from 2-4 gpm, and a washing machine from 3-5 gpm.
Toilets that are dated 1994 to present time fall into two main flush volumes, 1.6 and 1.28 gallons per flush.
The easiest way to determine the gallons per flush (gpf) is to check for a stamp near the back of the toilet bowl. If you are unable to find a flush volume stamp, try to locate the year the toilet was manufactured (for tank-style toilets only).
Our whisper-quiet American Standard Champion toilet is virtually clog-free and so powerful it can clear a bucket of golf balls in a single flush.
Yes. 2000 Flushes Automatic Toilet Bowl Cleaner is safe for plumbing and septic systems when used as directed. 2000 Flushes tablets should only be used in a toilet that is flushed regularly (at least once a week).
A WaterSense rated high efficiency toilet has been certified by the EPA to provide the highest standard in efficiency, water conservation, and performance. They use roughly 1.28 gallons per flush, but provide the same experience you expect when you need to flush.
Low flow toilets are toilets that use 1.6 gpf or less. Standard toilets use more than 1.6 gpf. Typically, the range is 3 to 5 gpf. These are no longer being produced and are not allowed by code, however, many existing installed toilets are older and use this high level of water for flushing.
A 1.28 GPF toilet is designed for low water usage, which can be beneficial for conservation. However, these toilets may require multiple flushes to completely clear waste, especially if you're dealing with toilet paper or other debris.
In 1992 US President George H. W. Bush signed the Energy Policy Act. This law made 1.6 gallons per flush a mandatory federal maximum for new toilets. This law went into effect on January 1, 1994, for residential buildings and January 1, 1997, for commercial buildings.
The wax ring is exactly what it sounds like: a ring made of sticky wax that helps form a watertight seal between the bottom of the toilet and the sewer pipe. It requires no maintenance and can last 30 or more years, often as long as the toilet itself. But sometimes wax rings can dry out, crumble, and fail prematurely.
On average, most toilets will have a lifespan of between 10 and 15 years, even with regular use. The lifespan may vary depending on the toilet model and the wear and tear it experiences over the years. Most toilets will start to give you warning signs indicating the time for replacement is near.
Final Verdict. The overall best toilet is the Toto Drake Cotton, thanks to its powerful flushing action, comfortable height, and advanced ceramic coating.
Elongated toilets can have a more powerful flush system, which may avoid having to “double flush.” Elongated toilets require more room than a round toilet, so take this into consideration if space is an issue. Round toilets can be installed for potty training, then replaced with an elongated one as your child goes up.
Because commercial toilets typically get a lot more use than residential toilets, they need a more powerful flushing system to handle all the traffic. Commercial toilets in high-use areas use a sensor to automatically flush the toilet. This sensor makes it less likely the toilet will get clogged or overflow.
