Danco HYR460 HyrdroRight Water-Saving Toilet Tank Repair Kit with Dual Flush Valve, Includes Dual Push Btton Handle in Chrome

The Danco HYR460 HydroRight kit was surprisingly easy to install, even in my Mansfield toilet (despite the incompatibility warning), since the flush valve had been previously replaced with a normal aftermarket one. The instructions were clear, and the installation process itself was straightforward. I did encounter a minor leak initially, but this was easily resolved by adjusting the flush valve seal; I had angled it too much at first. While the plastic components feel a bit lightweight, they function well. The dual-flush system effectively reduces water consumption, and the split handle design is convenient, although my girlfriend initially found the buttons difficult to press due to her long nails. This was easily remedied with a small "push-stick." Overall, I recommend this kit for those seeking a simple and effective way to convert their toilets to dual flush and save water. 5/5.

Have now had installed for 6 months in one case and 2 months in two others. Working just fine. One advantage to these systems is the white slide mechanism on the filler tube. You can slide that so that it will not refill after flushing. This is a big help if have to adjust the replacement for the flapper value but even bigger help when wanting to clean the toilet bowl. Can slide to stop flow, flush using the liquids flush button and then with the bowl nearly empty can clean the bowl thoroughly. Then release the slide and bowl refills normally. Big help vs turning the water off at the valve. Same is true if going on vacation or away for weekend and want to prevent possible toilet overflow as mentioned below. Features not mentioned in other reviews I have seen on the product but a big plus for it.This us update to earlier note. I have now installed three of these systems. The only issue I had was getting the flapper replacement installed so it did not leak. But once that problem was solved the system works great. One item I have not seen noted but important to me is that you can slide a white slide on the arm of the filler mechanism to lock it in place. Very useful if going on vacation or even away for weekend as it could prevent a toilet from overflowing as friends had happen a few years ago with major damage. Beats turning water off to the whole house as the major risk is from the toilets. System worth it just for this! Also when checking for leak you can mark level with pencil and lock the filler and then go back in a few hours and see if level has dropped. Likewise if you have to adjust the flapper replacement it is easy to do by locking the filler when water level is low and then twisting the large part off of the flapper replacement and adjusting to be sure no leak. After doing this can release to let water part way in and then lock again and mark so do not have to fill entire tank (or drain it). Thought these useful enough to pass along.I initially bought each of these separately so my review of the filler valve and the dual flush valve are under the individual parts except that I am only adding the comments above to the entire system link. I have replaced the innards of toilets numerous times over the years and found this system very easy to install. Only caution I would pass along is to read the directions and the warnings with some care before you attempt installation. I have for years used bleach tablets in the tanks and I note that they warn not to do this with their system. Each part of the installation has some simple instructions but important to read them to save yourself a lot of frustration. When I first installed the dual flush I did not follow instructions to put water over the seating valve and mark with pencil and let sit 15 minutes to be sure it was seated. As a result I had to go back and redo the installation. Once you have done an installation for one toilet doing others will be extremely easy. So far system is working very well but I plan to wait a couple of months before buying more and installing in my other toilets. If this works as well as I hope I will be using these from now on. Especially attractive to me is replacement of flapper valve and those of us with hard water tend to find build up of sediment and lime allows leaking of the flapper over time which can waste a great deal of water from a very slow leak that you may not realize is occurring. If I find problems with the units after installed a while I will come back and revise this review. As of now I can recommend this unit both for ease of installation and how well they are operating so far. Some of the problems I have seen in other reviews have yet to show up for me. If they do I will edit this review.

Good product for an old toilet repair. Since it provides a new seal mechanism for the tank, you don't need to remove the tank to replace the bottom flapper seal, i.e., the unit provides a self-contained gasket within the kit.The two button flush is a nice touch but the water saver button doesn't really work with an old toilet that always requires a full flush. Still nice for toilet cleaning and using less water.The fill hose is not very well designed as it is flexible and will not lay down on the bottom of the tank as envisioned. I ended up using a rock to weigh it down so it stayed in place. A good design idea, but does not work as designed. Without the rock holding the fill tube in place at the bottom of the tank, it will lift up and spray water all over. I tried bending the hose to take the kinks out but had no success. The rock work well enough and maybe the tube will become more rigid and stay in place by itself over time. I guess you could also turn the water supply line valve down to reduce pressure and increase the tank refill time.
