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

Like! with the installation instructions this was a piece o cake. Now! can you send me my plumbing license?

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.

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.

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.

I installed this with the dual flush kit by the same company.The install was easy and the product is very well thought out and very adjustable to get the best water usage.My only disappointment was that it advertises that it can "detect leaks". Upon reading the manual this appears to reference a lock out feature that allows you to lock the valve such that it won't actuate when the tank level drops. This would allow you to check for a tank leak or do other service without shutting the water off, but its still a manual process where my impression was that it was some kind of automatic feature. The same tests could be performed just by shutting the water off.Still I'd buy it again and probably will as I service 6 toilets between my house, investment properties and my parent's house.

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.

Will work in beginning but after a few weeks have to tweak and adjust or water will creep over the water line then overflow. this happened on all 3 toilets. The adjusters will finally just not work (tried every adjustment to lower the water level) which will cost more in water bill. I just finally threw them away. These are tested for short term (likely where all 5 star reviews from) not long-term. Got the Fluidmaster 400H-002 Performax Universal Toilet Fill Valve and worked great.

Excellent product and super easy to install. I arrived home and had the old one out and the new one in, in about fifteen minutes.

Works, is adjustable and price is excellent.

would buy again

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.

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.

very quick and easy to fit.... no plumber needed
