Cable broke 1 year and 2 months after installing. Has the manufacturer come up with a solution?

Many people are having the same problem.
Asked by: ron
We had the same cable break, less than two years after installing. Friday night before Easter with a family gathering planned for Sunday. Have to wait until Monday to see if the replacement cable will be sent.

Is everything I need in this kit?

I need to fix s running toilet and figured i might as well convert to a water saver while at it. All the guts of my toilet look old, rusted, bent and on its last legs. Assuming I want to replace everything I see when I lift the lid, does this contain everything I need to do that? If not, what else do I need to buy? Do I need to keep any part of my current system? If yes, which part and if I need to replace that because mine is old, what do you recommend and shat is involved in doing that? I live far from the nearest Home Depot (2 hour round trip) so I want to make sure I get everything I need in one trip.

Duo Flush System Toilet Converter is rated 2.7 out of 5 by 209.

Bought these for all 3 of my toilets. 2 have broken in less than a year. If the cable snaps that runs from the handle, there is no way to fix or replace it. So you can't flush, nor can you just reach in and lift the flapper. The whole thing is poorly made. Looking at all of these negative reviews, I am surprised Home Depot still carries these. Had I seen the reviews first, I never would have purchased these. Went back and bought the old school setup.

Rated 1 out of 5 by from Waste of money Never would make a good seal so the toilet always was leaking and filling. The old school float and flappers are better than this plastic junk!

The Duo Flush System was easy to install and I like the lever action better than the "button" type. BUT....this is my second one. The first one worked fine until, suddenly, it simply stopped working. After only 9 months. Pull the lever up or push down and nothing happened. No way to manually flush the system either. I purchased the first at a different store (chain) so I returned it and shopped Home Depot for something different. I found something different but every single box on the shelf had been opened and it appeared that there were likely parts missing from each. So I bought this one (again). Hopefully it lasts longer than the first.

I replaced an older Duo Flush with a broken flush cable with this latest model. It is easier to install because the tubing from the fill valve to the overflow no longer has to be routed through the flush unit. I was happy with the ease of install. I'm sure it might be a challenge for someone who has little experience working on a toilet. I noticed that the directions did not explain the purpose of the blue clip valve to the overflow but one could make a good guess. The handle action of the new unit seems more positive than that of the older. Overall I'm happy with the performance of the new Duo Flush.

Then, every fews days, when I flush, the unit tilts up and water runs out the bottom. The angle adhesive piece does not stick well. Always dripping into the bowl. Every few hours, I would hear the toilet refill what had dripped out. The water flow is no different if I lift up or push down? The dual flush feature does not work. I ended up replacing the entire toilet. Cost more, but took much less time than swapping this out. This was a waste of time and water. I assume the people who give this 5 stars do not have angled seats? If true, problem with that, you do not know if you have a angled seat until you remove the old unit.

Rated 1 out of 5 by from Design Flaw Results in Early Breakage We've installed two of these in the house. Twice now, the cable has severed at the ball in the valve portion of the device. It just does not stand up to demands of a many person household. Getting a replacement cable is next to impossible so I've had to buy another kit (and probably will not do so in the future). I've an extremely busy schedule and the 'fixer' of the house so I've got no time to make calls. The customer service section required a phone conversation within 48 hours of email contact---I work 12-15 hour days in a remote location so this is impractical. THIS CABLE SHOULD BE AVAILABLE FOR PURCHASE from the manufacturer as it is not IF but WHEN it breaks. Since they have an average life of 5 months in my household I would think a cheap price for cheap parts would be fair.

Get some additional plumbers putty just in case your installation needs a little extra. I had the flat installation, be sure to clean the sealing surface of the existing toilet very well as that is going to be what gets seated to your new unit. The whole change out took less than 15 mins that also included the new float assembly. Read the instructions and have a sequence in place. To make things easy you will need the following a bowl to catch water when the float assy. is removed, adjustable channel locks, and a crest wrench. RRW

It doesn't have a flapper value but the value that it uses to hold the water in the tank leaked slowly. As a consequence the float would drop after enough water leaked out that the water would come on and refill. The toilet I used this in was the master bath and I would hear it all through the night refilling. I put some weights on the value in hopes of creating a stronger seal. That seems to have worked. I like having two flush settings but probably would not buy another unit.
