Danco HYR270 HydroRight Water-Saving Dual Flush Valve with Push Button Handle, Chrome, 1 Pack

I bought three of these sets. Normally I never complain about instructions, but I had some installation issues. Well, it was installed easily, but I had to hold the buttons to flash. The instruction talks about jammed cable. In my case it was not jammed, it was curved a bit more than device can tolerate. So, I found some examples on youtube and did it in the same way. After that, my issue was resolved. All other sets were installed without problems in 15 minutes each. Later one unit had some issues, but Danco's customer service was fantastic the problem was resolved.

Fácil instalación y muy eficiente.

I am using two of these items. So far, they are working fines. Yes, there is a bit saving in water but difficult to estimate the savings.

El producto está bien, es bastante útil y muy eficiente. Es una lástima que el botón de descarga dual sea de plástico y ya no lo manufacturen en metal como solía hacerlo la empresa.

As the headline suggests, I installed these in my parents' respective homes over 10 years ago with no complaints. Seems there's a handful of complaints about the seal thickness and leaking here, but that hasn't been my experience. Also, as others have said, depending on the age and configuration of your toilet (i.e., if it has a traditional ball float valve) you may need a new valve. I've used both the Danco valve included with the retrofit kit (not this product, but includes it in the kit), and and float less valves. Installation is super easy as a DIY project and the instructions are pretty straightforward as far as getting the thing into the toilet tank and running. Where I'd dock points is the explanations on optimizing water use, which they base on measuring the existing water levels in the tank and bowl. It's not hard to figure out, but directions are unclear. But just getting dual flush to work is easy enough. You don't need to be a toilet 'power user.' The other drawbacks: the pushbutton action and the button itself. Since the button lifts a valve fighting the weight of the water in the tank via cable pull, it takes a pretty heavy push compared to my purpose-built dual-flush toilet. Second, the button does not play nice with lever holes that aren't squarely on the front or side of the tank. On one installation where the lever was located at the corner, I had to shim it out with a stack of washers and it looks strange. Lastly, it's kind of an ugly chromed plastic button. Seems a lot of folks prefer the dual-lever version of this. It's a tall ask but I wish they had a choice of buttons to match bathroom decor. All in all, it's one of the few readily-available dual-flush conversions, and IME, they last, and it's cheaper than replacing your whole tank.
