Next by Danco HC550 HydroClean Water-saving Toilet Fill Valve, 10-1/2" x 3"

Let's face it, toilet innards aren't supposed to be glamorous. This one, however, comes close. The HydroClean was easy to install, actually looks nice (modern?) in the tank, and includes a couple innovative features. First, there's a small plastic clip that lets you lock the float in the "up" position. This allows you to flush the toilet without the tank filling again, which allows you to work in the tank without having to get on your knees and shut the water off at the wall. Second, there's a little dial at the top of the valve that lets you select how much water re-fills the toilet bowl. This lets you select the right amount of water, so you water isn't being wasted by over-filling after each flush. Finally, the valve directs water downward so as to clean the inside of the tank upon each flush. My tank, being old, has years of accumulated rust stains. It didn't exactly brighten the inside of the tank but it looks a little lighter. All in all, a great product.

Easy install, and adjustment.

Still works even 2 years later.

Quick shipment, clear instructions for installation, and a very easy installation as well. Though I did order units for both bathrooms, only one toilet was compatible with this model. The other has an oversized flush system, and that unit was returned, no hassle. I did struggle with adjusting the "water and paper" flush volume, initially. The directions are clear, I just didn't seem to understand them. My bad. This seems to be a very high quality mechanism, and has served us very well for over a year now. No problems, no requirement for readjustment.

Great product that stands out from the competition due to not having to remove the tank to install. Most of the dual flush valves require removing the tank to remove the original flapper valve seat. Not too big a deal, but I just did not want to take a chance on one of these dual flush valves if it was going to be any hassle. I installed this on an original to the house 1960 toilet. It installed easily, but I could not get the bowl to fill on the #1 flush even after the #1 flush adjustment was maxed out. This problem was solved by installing the adjustable fill valve that is recommended to buy with this product. After installing the adjustable fill valve and a few minutes tweaking the settings it works great. Buying a modern water saving toilet is definitely the right way to go, but if like me, you don't have the several hundred dollars to lay out for a new toilet, this is a great alternative.

Only Amazon would meet the challenge.My bathroom toilet is old and hard to replace however Amazon had the perfect replacement part.

For various reasons, I've had to replace inlet valves several times on our toilets, most recently when I installed dual-flush systems, and decided to renew everything while doing so. These units are simple to install, are easily adjusted for fill level, have a great little adjuster for the rate of fill of the bowl after a flush, and also have a little catch for locking the inlet valve closed (maybe for when you're working on the flush valve as I was, or maybe even for when the house will be empty for a while?). Very happy.

We have gone through 2 'fluidmaster' fill valves from Home Depot. On both the float quit floating in little time. One of them constantly hissed. I did not want to buy another lousy part, so I ordered this one based on reviews. We have had it for one week. It is functional and far better than the Home Depot part so far. This one is a little more 'adjustable' than most other parts, mainly that you can adjust the bowl fill rate to coincide with the tank fill rate, which will save water. Like other similar fill valves this one has adjustable heights for the stem and the float. The very fact that it works is not in itself enough for the 5 stars, but when I compare it to the other similar parts (which don't work), this soars. . . I recommend this over fluidmaster parts from Home Depot. 18months later: still working flawlessly.

The one minor snag I had while installing this was that the height adjustment was a bit "stuck" when I initially received it. I had some trouble figuring out what was wrong (in reality it just needed a good yank). Contra one reviewer for the HC660 model (which is the same but includes a "tank cleaning" extension), the included retaining nut worked fine for me. The bowl fill adjustment has been easy to use and reasonably precise. If I have problems within the next year or so (some HC660 reviews had issues with the float valve getting sticky) then I will update this review.

Installation was very simple, it took me no more than 15 minutes to remove the old piece, install and connect the new one and adjust the height. The installation manual is very clear. Good product overall, I would buy it again.

Works, is adjustable and price is excellent.

Good product, easy installation

This was an replacement for the exact same part. I originally tried a universal valve also made by Danco that I picked up locally, I couldn’t make it fit properly. This unit arrived in just a few days and was installed in a couple minutes. Well worth the wait.
