It is a very nice plug and play unit. Comes with a extra mount on the fill valve to accommodate most toilets. It has plenty of flushing power in both modes. It is adjustable but I didn"t have to change the settings at which they were set at out of the box. I would definitely recommend to others . Hopefully it saves as much water as estimated.

I installed 3 of the Duo Flush systems in the bathrooms of my house. The first one seemed to work well for several months which is why I purchased the other two. Bad choice on my part. I followed the installation instructions exactly each time. After about a year the plastic cable sheath snapped on the first one, making the flush mechanism worthless. The flush mechanism can't be purchased separately so I had to buy the whole kit just to get a new flush mechanism. Waste of money.

I noted that the cable and flush mechanism had been redesigned on the newest model; clearly Fluidmaster knew something was wrong with the old design. And only a few months later I found out what was wrong.

After about a year of use, BOTH of the other Duo Flush systems I purchased failed identically less than a week apart from one another. Making this the THIRD failure our of THREE purchased!! BOTH of the cables snapped off internally to the flush mechanism. BOTH of the cables had rotted and snapped off. All three units failed after less than a year of use!

I wanted to save water because of a constant drought in the area but I've now wasted $75 on worthless water saving equipment! I'm so furious with these products I'll never buy another one! Sure I saved some water, but not nearly enough to pay for all these poorly designed Duo Flush systems! Now I have to spend even more money to replace these worthless Duo Flush systems! I'm infuriated with this product and how poorly it performed over time. What a waste of money!

I have bought 2 of these units for the same toilet. Both of them the cable has broke at about one year. The first time didn't think much of it, just got a new one and keep the old one for parts later. Now the cable has broke on second one and can't find just cable. Had installed on most used toilet in house though would save on water. The valve and float assembly has worked fine on both units it just the cable that is the problem

Comments about FLUIDMASTER 1021686 Fluidmaster Duo Flush Complete System (550DFRK-3):

Purchased this 6+ years ago to adapt a cranky 70's Gerber toilet. Installation took some planning and watching YouTube videos, was pretty straightforward with that preparation. (I've been repairing toilets since first living in a least-developed country 35 yrs ago.) Solid-liquid balance took awhile. Bought second kit to install on another toilet. Notable water savings.

This devices has given me problems from the beginning. First the instructions are not detailed no information especially how the Valve fits. I put it on and tried every different position and it does not seal. The toilet runs on its own sometimes. This is aggravating
I am going back to the flapper

Save Your Money. Do Not Buy This Product.

Comments about FLUIDMASTER 1021686 Fluidmaster Duo Flush Complete System (550DFRK-3):

I am truly not satisfied with this product. I converted all three of my toilets in January/2014 to the DUO FLUSH system. I purchased this product because I was intrigued by the dual flush system, the potential water savings and due to your advertised 5 year warranty. My problem with your system is that the cable continues to break, and therefore I need to repeatedly purchase and replace the DUO FLUSH Valve. At over $30 a replacement it has become very costly to run this system in my toilets. Unfortunately I thought I had bought a good quality product and threw out all my old parts, so I can't convert back. Here is a history of what I have purchased so far:

January 6, 2014 purchased 3 (installed in 3 different toilets)
May 31, 2015 purchased 1
September 3, 2016 purchased 1
December 19, 2016 purchased 2
September 23, 2017 purchased 2 (1 not being used as it is a spare)

Add it all up and it has cost me over $270 for 9 units over a 3.75 year period. I am thinking of replacing my toilets, as the DUO FLUSH option has turned out to be way too expensive.

Good idea poor design. We installed it in our office to test before making a recommendation to clients. I'm sure glad I did. In three months we quadrupled our water usage.

The flaw seems to be that their is no prevention from the valve sticking open. Two bills later and we used 22000 gallons one month and 19000 the next bill. This is from 8500 gallons.

I have to keep buying the whole kit over and over

Comments about FLUIDMASTER 1021686 Fluidmaster Duo Flush Complete System (550DFRK-3):

The flush/fill part only works for ~6 months before you have to buy the entire kit again (they don't sell just the water fill side) doesn't save
On water because starts to run if handle isn't perfectly level, then the seal stops working and slow constant run of water into the bowl. Cannot get the kit out of the tank to switch it back to the original equipment so we are stuck in buying the duo flush every 6 months or sooner. Never put this product into your tank you will be stuck and throwing money down the bowl seriously. I would put zero stars or negative but it's not an option.

Fluidmaster has the most excellent customer service. I have an older design dual flush conversion system installed in my tanked. Unfortunately, the flush handle cable degraded at the ball end tip. One call from their customer helpline and I was shipped the part immediately. I can only wish all companies conduct their business the way Fluidmaster does.

    This product is pretty good. It was easy to install and seems durable. It definitely does use much less water than my old product and only needs one flush. I recommend and would purchase again.

    Will not work in Toto one piece toilets

    Comments about FLUIDMASTER 1021686 Fluidmaster Duo Flush Complete System (550DFRK-3):

    Unfortunately all 3 of the toilets in my house are Toto one piece toilets which have a 3" opening for the flush valve. These units are built for the standard 2.5" opening and therefore would not fit these toilets. I was not going to give any stars since I can not honestly review this product but the system requires at least 1 star. This does not mean I thought it was a bad product, just that I was unable to use it.
