This is a great kit to retrofit your old system and save more water than most dual flush systems on the market today. Be sure to read the specifications to make sure you current toilet tank will be compatible with this system. Made from plastic. Comes with a dual flush handle. I installed this unit is less than one hour and it works great with the default adjustments on the top of the flush valve. I will try to fine tune and save as much water as possible. Many reviews discuss the wire from the handle to the flush valve assembly. Make sure it is routed correctly and avoid any sharp bends and do not force the flush handle. If it does not move easily, check installation.,

We needed to do something about a toilet shut off valve that had begun to leak, so we decided to try one of these things. It is a complicated system with lots more moving parts than an ordinary float valve and it has some quirks. It will not work in all toilets so you have to check for compatibility first. We got lucky in that it fit our tank but I would not recommend that approach. It passes noticeably less water in the half flush mode which is as it should be. I had to rotate the flush handle 90 degrees because it would not operate in half flush at first. The handle contacted the edge of the lid and so would not trigger the flush as it was supposed to, but will work if mounted hanging down as pictured. I would not recommend taking a toilet apart that is functioning properly to install one of these, but as a repair of a malfunctioning system , it does work.

This is seriously easy to install. The directions are detailed, yet simple. Following them made the installation accurate but easy enough for even a beginner. I was skeptical at first because of the dimensional requirements (recommendations) listed for the top of the fill valve vs. the overflow. I contacted the tech support group at Fluidmaster and received great support and insight not only for their product but the whole retrofit concept and proper ways to use as much or as little of their system in the conversion. Things I really never thought about, I changed to eliminate the possibility of a water disaster because of a stuck fill valve and Improper height overflow.
So lower went the overflow, to the circular file went the old fill valve, flapper and handle. Cleaned the surface of the flush valve as noted in the instructions and within ten minutes was completed with the Water adjustments for the half and full flush.
I did have 1 more misstep where I used the optional lever gasket and called the tech support group again to find out that's why the handle wouldn't return to the proper position w/out help.
This Duo-Flush system now works excellent and I have found yet another company with a great technical support group. I will highly recommend this product, this manufacturer and their support people 100%.

Rated 1.0 out of 5.0 by witterik Will Break in 6 Months
I have 3 toilets in my home and decided to install this in all 3 to make them dual flush and save water. The dual flush works by running two cables to the flush handle. Turning the handle one way pulls the first cable and you get a half flush, pull the other way and you get a full flush. Problem was that the cable breaks and the system stops working entirely. The first time this happened I contacted fluidmaster and they promptly sent me a replacement. Since then, the replacement broke and another in one of the 3 toilets broke. So that is 3 of 4 breaking in the same way. Please do not purchase this product. It will fail.

I take reviews very seriously and was a little concerned with this product but it appears that Fluidmaster is standing by their product. I can can say I love the idea of using less water for removal of liquids in our home of three adults. The product was very simple to install. The parts are all plastic so only time will tell how well and for how long the system hold up. I have high hopes for that this product will have many years of service in our home.

Rated 4.0 out of 5.0 by GPM1972 Poorly written/illustrated instructions
Supposed to be a "universal" system but after I got it home and read the instructions, it said the kit would not work with 3" flapper valves. Mine has a 3" flapper valve. I removed the 3" rubber flapper valve and determined the flush valve assembly was angled. The kit comes with an adaptor to make the angled flush valve assembly flat. It fit mine perfectly so I pressed on. The biggest time waster was getting the cable adaptor to snap & lock on the new handle assembly. I finally figured out the supplied plastic nut for attaching the handle assembly to the bowl was too thick. I had to use a sander to thin the plastic nut. After making adjustments to the fill valve and the flush valve for 1/2 & full flushes, it works pretty slick.
