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
I had three break in two years (the most current today, 8/25/2016) and was not happy. I called Fluidmaster's Customer Service and their representative handled this situation great. He told me there was a change in the mechanism and they had not had a complaint due to a broken cable in seven months. They are shipping a new unit to me that should arrive on 8/29/2016. It will snap into the existing base so we'll see what happens.

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.

Customer Reviews

Duo Flush System Toilet Converter is rated 2.6 out of 5 by 194.
Rated 1 out of 5 by from 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.

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 2 out of 5 by from cheap and doesnt last Installed two of these. After a year the cable on one broke, and then a month or so later the other one broke. Also had problems with the flapper sticking and not sealing which led to a flooded bathroom one day. Handles are cheap and flimsy and creak really loud when you twist them, but you have to twist them hard or the flapper valve wont engage right and youll only get about a cup of water per flush. Going back to conventional system.

Rated 1 out of 5 by from Broke within a year Straight forward install. Cable broke in less than a year with minimal usage. I do not recommend this kit. In theory it is great, but quality is terrible.

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!

Rated 1 out of 5 by from Horrible We have bought two, both broke within 6 months. I want my good old fashioned chain back. Horrible product.

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.
