Danco HFX320 HydroFix Toilet Repair Kit for 3-inch Flush Valve Toilets, Fix Running, Noisy, and Leaky Toilets

Water Inlet threaded is not compatible with standard fittings in UAE, so you can't connect to water supply.

Arrived quickly and installed smoothly, fixed a running toilet. I found the instructions a bit confusing but the video in the Amazon listing was very helpful. It seems like it will last a long time.

Well made components and very easy to install. Very well engineered and extremely easy to adjust (without tools). The tank fill level can adjusted by turning a threaded linkage and the toilet bowl fill level can be adjusted by means of a quarter-throw lever-- very nice. No more grimy brass or plastic screws to see-saw adjust.It's quite evident that every part of this product was well thought out. Even the valve nut was engineered so that it could not be over tightened (a common mode of failure for leaks at the tank/valve union).Be sure, when installing the valve nut that the valve tower's seal is well seated into your tank's opening. If it's off, even by a little, you'll have a leak when the tank fills. A gentle "jiggle" (yes, that's the official plumbing term) while hand tightening the nut helps prevent possible leaks during installation. The instructions state, "1 - 3 audible clicks" until tight, however that would be fine if you toilet's tank is dimensionally perfect. Use your judgement as to how tight "hand tight" is so as to make sure it won't spring a leak.Fill times are dramatically faster than what I previously in my tanks (in fairness, they were 15 year old float valves). On a very old Cranada 6 LPF of almost 3 minutes this valve pulls a 44 second flush-to-fill time.I'm not quite sure why I didn't replace my toilet fill valves with this type of system before now. Thumbs up!UPDATE: 11 months on and it's doing great. The only problem is that the flapper chain fell off once-- easily remedied by a cable tie.UPDATE: +7 years on and it has finally shown signs of failure. The main valve body has developed a hairline crack when the valve is open/filling the tank. I will likely replace it which the same model or a FM brand but this exact model has skyrocketed in price here. That said, I am happy with the performance over +7 years considering the original price paid.

For a few dollllars more than your standard tank repair kit, I purchased this one. It promised a few key benefits, and delivered on them.Some of the features advertised on this kit are standard with a normal kit:1. Setting the amount of water that fills the tank - this is done the same way as a normal kit, by adjusting the height of the float with a screw - easy as cake.2. Water savings on a flush - this is a bit debateable since any new fill valve will save water over what's wasted by a broken one.3. Flapper - the flapper in this kit is nothing special. Feels kind of flimsy actually, but it gets the job done.Some of the unique features offered by this kit:1. Calibrating the amount of water that goes into the bowl through the fill tube - This is the best reason to buy this kit. With a simple lever you can adjust the fill amount to a reasonable level. My toilet was from 1984, and wasted a lot of water by overfilling the bowl every time. The amount of water I save with just this adjustment will pay for the kit in no time.2. Tank Cleaner - A neat little feature, it basically sprays water around the tank to clear out any debris and help prevent anything from growing there. I had a lot of small pebbles in the tank that had accumulated over the years, and within 3-4 flushes it had pushed all of them into a nice little cluster next to the flapper, and they all were flushed away quickly.3. Fill lock - This isn't fancy but it gets the job done. it's a small piece of plastic that allows you to lock the pump in the "off/raised" setting and prevent the tank from refilling while you are adjusting the flapper, changing the pump height, or whatever else you need to do.4. Easy installation - No tools required and took me about 10 minutes to install, and I was pretty careful. Totally painless.I haven't had a chance to use the leak detection feature yet (and hopefully won't ever have to).Overall I think this kit is great, offering a lot of extras you won't find on a normal repair kit. The high level of adjustability will likely offset the higher cost of this kit in the long run. Highly recommended.

Easy to install. Comes with all the tools. Recommended product.

Went to Menards where I had purchased this same kit about 10 years ago (still working great). Unfortunately they no longer stocked it (go figure). There were a few other manufacturers, but I was sold on Danco. So of course, I found it on Amazon. A great price for a great kit. Installed it in my other toilet and it works like a charm. Like my other toilet, it is quick to fill, saving on water. Installation is a snap. I highly recommend this kit.
