## Description

Product Description The Danco HYR451T HydroRight Total Repair Kit increases your toilet’s efficiency with an included Dual Flush Converter that will save water by reducing the amount of water used with each flush. The HydroRight will also help solve the most common leaking issue in toilets, a non-functioning flapper. The Dual Flush Converter sits vertically and solidly onto the flush valve opening to create a better seal and eliminate the possibility of leaks. No more leaky flapper, tangled chains or handles that have to be jiggled. The Total Repair Dual Flush Valve quickly and easily converts a standard toilet into a two-handle, dual flush toilet. The short center lever is the Quick Flush setting that uses significantly lower water volumes for liquids and paper - the setting needed 4 out of 5 times. The second complete push lever at end is the Full Flush that uses the normal amount of water for solids. Designed for drop-in installation, the HYR451T can be installed in without tools and without having to remove the tank. From the Manufacturer Next by Danco exemplifies a line of state-of-the-art plumbing repair parts that empowers the DIYer and Professional to do more than just solve the problem. Don’t just repair it. Improve it.

Review: Best one yet - Everything about this works great, just one detail to pick on. Where it goes into the big hole, very much wish there was a long cylindrical rubberized tube. Item is so light it had to be engineered to stay in place. Otherwise, very quiet, flushes extremely well, and very easy to use. Very sorry I bought a Home Depot, this really was that much better.
Review: Had to replace all the inside parts... - 11/21/14 Updated to 4 stars: Okay so now it works fine. I ended up having to replacing the flush valve to obtain a proper seal after the flush. Apparently I had a better seal with the old flapper and flush valve but it still ran so it needed to be changed, which is what started this conversion. Now I just need to figure out how to adjust it properly. The partial flush doesn't flush a square of paper at this point but the full flush works fine. Eventually I hope to have it adjusted properly. End result after all is pretty good. I guess I will have to see how it holds up over time. Happy with it now! Right now I am not happy!!! I have installed and re-installed 3 times. I read the instructions a few times before installing and watched several videos. I have installed many of the typical setups in toilets before. The installation was easy, no problem each time I tried it was quicker and everything seemed to be great each time until I let the water into the tank. The tank fills properly, but once full the water continually drains from the tank causing the refill to go on every few seconds no matter how many times i take it apart and re-seat it. I guess i am just totally frustrated at this point and wanting to put all the old parts back on. I only changed them thinking I would save water. After all, we are in a drought here in California so anyway to save water waste is good in my book. So my next move I guess is to go to the hardware store and try to find all the rest of the internal parts to replace. I guess i need to get a new overflow tube and flush valve assembly and then try to re-install again with a completely empty tank and all new parts. I'm also thinking since this is a kit the flush valve and overflow tube should be part of it or the first instruction should be: Go buy all new parts first so you won't become frustrated after trying to install. My opinion only! Am I the only one with this issue? If anyone has any hints I am open to them. I don't feel i am installing incorrectly but then again I'm not a plummer and just following instructions. When I try again, if it works I will come back and update. I was really hoping this would have been a 15 minute to 1 hour job and not a few days. :(

## Features

- WATER-SAVING DUAL FLUSH TOILET REPAIR KIT: Easily converts a standard toilet into a dual flush toilet that saves water by reducing the amount of water used with each flush. The permafit silicone seal is also chlorine and chemical resistant and will not warp.
- ELIMINATES TOILET LEAKS: Eliminates common leaky toilet problems due to a worn-out flapper, handle or faulty flapper chain.
- HASSLE-FREE INSTALLATION: Drop-in installation without tools in 5 to 10 minutes - tank removal not required. This has an adjustable height of 11-13.8 inches.
- TOILET FLUSH VALVE COMPATIBILITY: The Dual Flush Converter works with standard 2 in. flush valves and requires a 10-inch minimum clearance from highest point of the flush valve opening to the inside of the tank lid. NOT COMPATIBLE WITH MANSFIELD TOILETS. The HYR451T combines two products that together will increase your toilet's efficiency: HYR271 Dual Flush Converter and HC630 HydroClean fill valve.
- DUAL-FLUSH LIGHT-TOUCH LEVER UNIQUE SPLIT HANDLE DESIGN: The short center lever is the Quick Flush setting that uses significantly lower water volumes for liquids and paper – this setting is needed 4 out of 5 times. The second complete push lever at end is the Full Flush that uses the normal amount of water for solids.
- IMPORTANT INSTALLATION TIP: Do not remove overflow tube and flush valve from toilet tank; the Dual Flush Converter is a replacement to the existing flapper; slide the blue silicone dome gasket down the overflow tube, seating the gasket into the flush valve.
- DETECTS LEAKS & WATER ADJUSTMENT CALIBRATION: Detects leaks and signals when a leak is found. The Total Repair Kit also can be calibrated to adjust the exact amount of water needed which saves water.

## Questions & Answers

**Q: This this work on a sloped flapper?**
A: I installed this in my girlfriend's toilet, and it has a sloped drain.  I thought I needed the plastic spacer to attach the drain valve assembly, but it did not seal. After realizing there is a rubber bushing/spacer, I replaced the plastic shim with the rubber and that stopped the leaking. So far this proves to be holding.

**Q: Will this work in any standard toilet?**
A: This also doesn’t fit older side flush Pegasus toilets. You need at least three inches clearance between the center of the handle mounting hole and the riser tube for the fill  valve. The handle assembly for this kit is very bulky and will interfere with the float if there isn’t much room.

**Q: Does this fit a kohler ellison toilet as a replacment part? is there any thing else i need?**
A: As long as the lower rubber seal fits the tank drain. Don’t place too much pressured on unit, or will deform seal, and the tank will drain.

**Q: anyone tried this on a mansfield? sounds like i need to convert to flapper before install**
A: This kit requires the flapper and the overflow value to be separate, though there is NO mention of this anywhere that I can see. You have to attach the big white piece to the overflow value, and the blue thing at the bottom sits where the flapper was. On a Mansfield toilet, there's no way to remove the plastic piece that serves as the combined flapper/overflow valve without disassembling, so there is no way to insert this thing. I considered trying to replace the weird combo piece with a separated assembly, but then I decided to just buy a Niagara toilet and save myself the headache. Mansfield toilets are dumb.

### ⭐⭐⭐⭐⭐ Very pleased with this replacement system
*by P***3 on February 22, 2013*

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.
