Essential Info

Reduce your water bill by 10% by installing the One2Flush Dual-Flush Conversion Kit. The easy-to-install kit can save homeowners more than 10,000 gallons of fresh water a year. Depending on water district rates, a dual-flush toilet can begin paying for itself with the first flush. Push the handle one way to rinse liquids, push it the other way for a full tank flush for solids. This simple concept has been used in Europe and in commercial applications for years. Now, instead of replacing the entire toilet, simply install a dual-flush retrofit valve and begin saving water and money. Rather than use the entire tank to flush liquid waste, the One2Flush valve uses just enough water to rinse the bowl. The water savings add up with every flush. By installing One2Flush communities pump less water to the home, process significantly less wastewater and decrease landfill usage by not disposing of old, non-degradable toilets. One of the simplest water conservation tools available!


More Info

An eco-friendly, green product
Because the One2flush requires less water, it takes in less water and sends less wastewater to area treatment plants and septic systems. Imagine if entire communities installed the One2flush! And because the One2flush gives new life to older non-degradable porcelain toilets, landfills across the country will require less space. That's good news for America.

No need to buy a new toilet
You'll find plenty of dual-flush toilets on the market starting at $200. But with One2flush, you can retrofit 7 toilets for the same price. So hold onto that porcelain toilet - it's about to work harder than ever for you.

Superior over traditional toilet repair systems
Until now, toilet repair options were limited to individual flapper, gasket, fill valve and flush valve kits, with the homeowner as detective, trying to decide which part needed to be replaced. The One2flush is an all-in-one product, eliminating any guesswork. And traditional manufacturers use flimsy propylene for their housings, and rubber for their flappers and seals, which eventually break down from constant exposure to water and common household cleaning agents placed in the tank. One2flush uses tough, recycled ABS plastic and longer-lasting silicon seals for strength and wear. Once you install our unit, you can forget it's even there.

PISSED OFF AT ONE2FLUSH -- Orange CA   7/26/2013
This One2flush is hard to install, requiring disassembly of the tank from the bowl, removing the old flush tube, and assembling the new unit in. It's a hard, lengthy and risky procedure for average home owner that may cause the toilet to leak in many places. After wrestling for 3 hours to remove the old rusted bolts, finally installed the unit. After using it for 6 months and kept adjusting and testing this unit, IT JUST DOES NOT WORK AS ADVERTISED. THE HANDLE BOTH WAYS DUMPED THE ENTIRE TANK. WORSE YET, THE RUBBER VALVE GET STUCK MOST TIME, NEVER STOPS DUMPING WATER INTO THE BOWL, INSTEAD OF REFILLING THE TANK. THE HANDLE IS ALSO FLIMSY and SEEMS TO GET STUCK A LOT. When the valve wont close I would have to wiggle the handle to close it. I also bought 2 BLUE SOURCE valves. This unit works as advertised. much easier to install and feel much sturdier. I am MAD at this BS by ONE2FLUSH. I want my money back! NTO RECOMMENDED EVEN TOP MY ENEMIES.
KEVIN -- clearfield, UT   4/20/2012
Install was easy even with having to take the tank off. Lever handle has a little more play in it than I'd like but it still works. No directions for what the RED knob does on lever control.
SON -- north andover, MA   6/5/2011
The thing does not work as claimed. No matter what I adjust, both ways release the same amount of water. Also, your price is 25% over the local store the sells similar item.
TOMMY -- summerside, PE   5/26/2011
Bought 2 of these and installation took about a half hour each and they work awsome .Highly recomended
HERBERT -- chicago, IL   5/26/2011
Sorry, I have not attempted to install this unit yet.
KEVIN -- indianapolis, IN   8/5/2010
Very cool product. Easy to install and works great.
BRENDA -- highlands ranch, CO   7/29/2010
This should hopefully help save some water and water costs. Nicely designed.
JOHN -- wakefield, VA   7/5/2010
Works Great! Highly adjustable... this will save a lot of water.
KEITH -- rochester, NY   6/17/2010
This product was easy to install, and works as advertised. Pressing the flush handle to the right uses half a tanks worth of water, to the left a whole tank. It's amazing how many times a half tank is sufficient. I'm going to upgrade all of the toilets. Smarthomes service and shipping were impectable. Thanks.
MATTHEW J -- plymouth, MI   6/14/2010
I purchased one of these just to try out. I have now purchased an additional 2. All toilets in my house now have this device. I have the install of the device down to 20 minutes. The water volume for the 2 flushes is very easy to adjust. I have had the first one installed for 1/2 year with no issues. The device is of high quality and works as advertised. I recommend this product because it is well made, is well designed and it help preserve water.
Rae Ann -- galesburg, MI   4/29/2010
The One2flush made my current 1.6 gallon toilet more efficient than those expensive new 1.28 gpf HET toilets for a lot less. And I didn't have to replace my flooring or repaint the wall behind the tank. I wish someone would tell the EPA about this thing. It works great and is saving us money.
MATTHEW J -- plymouth, MI   4/16/2010
This device worked exactly as described. My biggest concern when I tackle any plumping project is water leakage. My toilet was 10 years old and the seals from the tank to the seat portion of the toilet were reused without issue. The whole replacement took about 30 minutes including the time to find the tools I needed. I am still working on adjusting the water levels to optimize the amount of water I save. I will likely buy another 2 units for the other toilets in my house.
DALE -- chatsworth, CA   3/30/2010
Description not accurate. Capability of full flush is not per toilet but per kit. Not appropriate for older toilets! New toilets don't need it!
