MJSI's HydroRight dual-flush converter easily and inexpensively transforms your standard toilet into a water- and money-saving appliance (view larger).
Saving Water and Money
Central to dual-flush technology is the water savings that can be realized by a quick-flush setting using lower water volumes for liquids and paper. A second, full-flush setting uses the standard amount of water for solids. Industry experts agree that four out of five flushes require only the amount of water used in the quick-flush setting—meaning 80 percent of flushes waste money and water on all toilets that are not dual flush. An independent study found that the HydroRight showed average water savings of 30 percent, with some instances reaching up to 50 percent. Not only does the HydroRight help to preserve natural resources, it also proves to be more economical than purchasing an entirely new dual-flush toilet, which can cost upward of several hundred dollars.

The Case for Dual-Flush Technology
Arriving first as dual-flush toilets, more recent plumbing innovation has produced dual-flush converters that retrofit existing toilets into dual-flush systems. The HydroRight converter includes a two-button handle that gives users the ability to select the amount of water being used during the flush: the quick flush for liquids and paper and the full flush for solids. Adjusting the water flow for both flushes is quickly and easily done inside the tank thanks to the HydroRight. In addition, because the HydroRight’s dome gasket sits in the drain hole rather than a flapper, problems associated with flappers—like leaks and broken or tangled chains—are eliminated. The USEPA estimates that 20 percent of all toilets leak up to 200 gallons of water a day (the equivalent of 73,000 gallons a year), mostly because of faulty flappers. Not with the HydroRight: To install, remove the old flapper and handle, slide dual flush down the overflow tube inside your tank and tighten, and replace the handle with button and set the quick-flush amount. No more jiggling the handle to flush properly.

Industry-Leading Innovation
MJSI, Inc., headquartered in Shorewood, Illinois, is the manufacturer of a portfolio of products that are devoted to water conservation and sound environmental plumbing. Recognized as toilet-efficiency experts, MJSI’s innovation has expanded the plumbing market from repairs to improvements in efficient toilet construction. Not only is the HydroRight the recipient of the Chicago Innovation Award, it has also been awarded numerous honors by Popular Mechanics, Handy magazine, and Hardware Retailing magazine.

Product Description

The HydroRight Dual Flush Converter quickly and easily converts a standard toilet into a two-button, dual flush toilet. One button is the Quick Flush setting that uses significantly lower water volumes for liquids and paper - the setting needed 4 out of 5 times. The second Full Flush button uses the normal amount of water for solids. Designed for drop-in installation, the HydroRight is the only converter that can be installed in without tools and without having to remove the tank. The toilet repair kit eliminates the flapper, chain and handle without tank removal.

Easy to install and works great.
Michael S. Gutshall
This can waste 10-100 gallons per DAY (yes, up to 100 gallons) - so if your goal in using the dual flush is to save water, think twice.
Mad Max
The flush buttons are very hard to push.

UPDATE (Dec 2011):
At Home Depot today I saw an end cap with an infomercial running about this gizmo. However, I took one out of the box, and I was so disappointed to see the same darn paper-thin gasket that I (and many others) have reported to them over the past 2 years. Additionally, the Home Depot staff said they get a lot of returns on this item.

This company knows that their gasket is too thin, causes leaks, and that including a higher grade gasket would cost them very little (approx 20˘ per unit). Somehow they can find the budget to launch a Home Depot marketing campaign & produce a new infomercial, but can't spend an extra 20˘ per product to prevent the headaches they're causing.

I'll add that my fixes work, but the silicone seal is NOT a permanent solution (already had to replace it once). If this gizmo is not ready to use out-of-the-box, and requires annual or semi-annual maintenance, it is NOT ready for the market. If you want a dual flush, you can get a brand new dual-flush toilet for under $100.

Original Review:
Ok, I also had two problems when installing this, and I have fixes for the 30+ people who have complained about similar install problems (same root problem in almost every instance). I predict that for MOST people, this dual flush device will not be an "out-of-the box" solution - you will need some troubleshooting not included in the instructions.

But I also predict that because of bad installs, some folks here (not realizing it yet) will have running toilets, or will actually use MORE water on the low-flush feature than they did before! Unless you measure it like I did, you'll never know.

I ordered this for the obvious reason to save water. As a male gets older, he needs to do the "liquid" flush more often.
It's important to heed what they say for tank clearance...ours barely made it! But with EXCELLENT customer support, (I was able to speak to the inventor himself), they were able to walk me through the adjustments.....Problem is, it didn't work on the small flush....my old water valve would not allow the tank to fill enough to do the job. I was advised to order their HydroClean water valve ($9.00+s & h), which is adjustable, so you can raise the level of the water in the tank to work the short flush.....this means you'll use a little more water on the long flush, but most of us don't use that that often. I only ordered one of the water valves because I wanted to make sure it would all work.....and IT REALLY DOES!!!!
The bottom line here is that, with their customer support (who all spoke perfect English, located in Illinois) were so great and helped me work through the problems. I installed the HydroRight on both toilets and have a HydrClean on order for the 2nd one.
I highly recommend the product.
PS. The people that wrote about their problems, most likely did not let the product support people help them.

Just completed installation of the HydroRight Dual Flush Converter and here is what I learned. Despite the time honored belief that "real men don't read instructions..." read and understand the instructions before you start.

If you have reasonable mechanical aptitude and can follow sequential directions the install is fairly straight forward. One of the most important starting tips to perform (before you do anything else) is take a pencil and mark the water line in the bowl. Simple, but a lot of people will overlook this and create unnecessary grief for themselves.

Also, take note of when your toilet was built. Just about every toilet has a date stamp under the tank lid or within the tank. Sounds simple but most won't even know which they own, a 1.6gpf or 3.0gpf toilet. Figure out what you have before you even think of starting. If your toilet is pre-1994 it mostly likely is 3.0gpf (gallons per flush) if it's post-1994 it most likely is 1.6gpf. Then just follow the included directions in the package or go to the company website.

After completing the installation is where a number of people also stumble, become frustrated and give up because they didn't fully understanding the instructions. If you keep the following points in mind and take the time to think things through you will save yourself aggravation, time and water.

1. Removing the HydroRight upper housing is simple and can be done at any time. If you've already installed the device, just turn off the water supply to the tank, flush the toilet and unscrew the upper housing about 1/2 turn (clockwise or counter-clockwise). When the 2 opposite tabs line up with their mating slots it disassembles.

I did not pay attention to this detail: the HydroRight Dual Flush is not compatible with ballcock valves, so I had to replace the valve first (paid another $12 for each replacement, but it was my fault anyway). I bought two units for testing, replacing the master bath first, which I did in about 20 minutes, including replacing the ballcock valve, no big deal. Adjustments were simple and quick. When I installed the second unit in another bathroom, I noticed the tank was leaking water slowly through the overflow tube, something I had not noticed when the original ballcock was in. It took me a while, but I was able to track the problem down to a crack at the bottom of the overflow tube, which I had to replace, but the problem was completely solved. Thanks to this decision to 'go green', my water savings will be even better than I had originally anticipated. Now I am buying another one for the last toilet at the house.
