Just the one included in the kit. It looks much better in real life (the pictures are misplaced/exaggerated). I took it apart in the store to make sure I could live with the looks, and it melds ok with the looks of the toilet (doesn't stand out like in the pictures). Maybe I could upload a picture of what it actually looks like on an actual toilet (probably not).

Answer: 
This replaces your existing equipment inside the toilet tank. If what you have in there isn't working, this will probably work since it's a replacement unit for what's already in the tank. Was easy to follow instructions for install. I got mine as part of the Home Depot Seeds program so I am not sure how much it costs. Good luck!

Answer: 
Check with HD for current prices. The unit comes with a large illustrated instruction sheet telling you how to install it. Installation is more complicated than some other types, but that is because the unit will turn an old toilet into a modern water saving unit. I've had mine for 6 months with no problems.

Customer Reviews

Rated 2.3 out of 5 by 127 reviewers.
Rated 4.0 out of 5.0 by Upgrade and Save Water 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., July 29, 2016
Rated 4.0 out of 5.0 by newfangled toilet flush thing 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. August 19, 2016
Rated 5.0 out of 5.0 by Best Toilet Conversion System Available 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%. August 22, 2016
Rated 4.0 out of 5.0 by Great Idea 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. July 4, 2016
Rated 4.0 out of 5.0 by Dual Flush should have been the standard decades ago This is another good product to save natural resources, (water in this case) and homeowner money. Installing this flush valve took me ~1/2 hour total. No special tools needed and all the parts were in the box. I'll need to admit that I 'cheated a bit' on the time estimate since I opened the box and read the instructions the night before and got my bucket, towel, sponge and channel lock pliers (just in case) ready to go for the project. This installs just like any other flush valve I've replaced, more than 10 in the last 30 years. I'll offer some hints that may be of help: 1) You may need the channel lock pliers to shut off the water supply line. I've installed a stainless steel jacketed flexible supply line long ago, and I'd suggest you install one. Makes subsequent repairs much easier than a solid copper / plastic line. 2) The nut holding the flush lever has left hand threads. Why, I don't know. 3) If you are replacing a similar fill valve (as I was, see pictures). Pre-set the height and float valve on the table before installing it in the tank. 4) Take your time cleaning and aligning the angled to vertical adapter in the kit. Point the indicator on it directly at the center of the overflow tube. 5) Most tanks have a 'fill line' already indicated in the tank. Use it to set the water level. See picture. There is a 'crush/pinch restrictor' in the bowl fill line, (that you clipped on the tank overflow tube) that is not mentioned in the instructions. It is the blue thing on the black tube that allows tank fill water to refill the bowl. Looks like the thing they use in hospitals on an IV drip bag... Presumably it is used to limit the bowl fill water usage, but not mentioned in the instructions. I currently have mine set to "Full & Half" (9 & 6 on the dial tuning knobs). Time will tell if I can decrease these settings further. The flush handle in my installation could not be installed in a horizontal position. Perhaps a redesign of the handle could maintain the 'standard' horizontal profile? The tank lid prevented the necessary 45 clockwise rotation to activate the 'small flush' function. I had to install the flush handle in a vertical orientation to allow enough handle rotation, clearing the tank cover. See pictures. Not a major issue for me, just needs some explanation to the family on operation. Perhaps they need to include a label that can be attached to the tank / cover that indicates: Clockwise (up) {Left} = 1/2 flush Counterclockwise (down) {Right} = full flush {and hold for a second or two} I had some fun with my label maker and attached one to the tank as a reminder. Sorry, I didn't attach a picture of my inappropriate label. I'm sure you understand... May 28, 2016
Rated 3.0 out of 5.0 by Toilet valve fix The packaging came with language instructions in non English so I had problems with installation, had to go back to store and get correct instructions from another package only to find out that I had to have another part not in the kit. Over all a little frustrating but got it working but not overly impressed with the product performance August 16, 2016
Rated 2.0 out of 5.0 by Keeps breaking in just over a year It is easy to assemble and works good until the wire breaks between the handle and the converter. This has happened to me twice. Both times it was just over a year when the wire broke. August 6, 2016
Rated 5.0 out of 5.0 by Great product design. Easy to install. Cable broken but Fluidmaster stood behind the warranty I bought this kit about 1.5 year ago. My family have enjoyed the duo flush system. Recently the cable broke, and we were a bit frustrated about it since not being able to use the toilet is annoying. My wife called Fluidmaster regarding the warranty, and the support team was very helpful and immediately sent the newer version of the product via extremely quick shipping. We received the product 1 day after the call on Saturday and was able to get back to use the toilet shortly after that. According to the rep, the newer version should address the cable issue, and we did feel the handle is lighter and easier to use. July 3, 2016
