Fast and quiet - nice upgrade

This valve provide a faster and quieter fill compared to the cheap builder-grade hardware it replaced. Installation was a snap and only required a pair of pliers to remove the nut on the old valve. Hand-tight on the new nut created a good seal with no drips, and the design allows you to get a good grip without tools. If you require a wrench to tighten enough to create a good seal, check to make sure there is no debris or sediment interfering with the sealing surface of the tank. I was so pleased with the results that I bought two more for the other toilets in the house.

Works great! Looking forward to many years of reliable service.

Finally received this today and it was pretty easy to set up. I have a Toto Carlyle II, and the only hard part of the setup process was the removal of the original fill valve which was attached to the tank using a hex nut. It was not easy to detach and required stooping low with a wrench to unscrew. I guess the bright side is I had a bunch of back and neck stretching workouts after doing this for 3 toilets in my house! Anyways, it turns out the original fill valve (Cyclone Flushing Systems by Toto, TSU25A) has a well-documented fail rate after a short while. As for the Korky fill valve, I love how the attachment bolt has knobs and does not require a wrench to tighten. They highly emphasize hand-tightening only without using any other tools, or you will compromise the attachment/seal. The only other tedious process was adjusting the bowl refill valve knob via trial and error at least 10 tries each time (I guess I was being a perfectionist, waste water now upfront to save water later :P ) to make sure the bowl water fills up just at the right time the tank water stops filling. This process was quite fun for me at least. Some videos recommend using a marker or pencil to mark the water line in the bowl after the water settles after a big full refill, but I find this unnecessarily disgusting. Here's a cleaner alternative: 1. Turn the bowl refill valve to the max setting. 2. Give the toilet a full flush. 3. After the tank stops refilling, wait 10-20 seconds and see where the water level is in the bowl. 4. Mount a flashlight/led laser pointer at a nearby sturdy location such as a sink counter. Stick the butt of the light source into a tightly folded towel and adjust angle as needed. 5. Note the point of reference (laser dot level or bottom rim of flashlight beam) and then turn the refill valve to a lower setting and flush the toilet again so that the water level gets filled below this point of reference. 6. Turn up the setting and continue to adjust the knob of the bowl refill valve to get the water to stop at that level just as the tank water stops flowing. 7. Personally I don't mind just a very little bit of overfill to the bowl to ensure the old contents are displaced out. To check, you should hear a slight split second of draining sounds after the tank stops filling. If there is no draining sounds after the tank stops filling, then either you have the bowl fill rate just right or it is underfilling.

easy to install, quiet and still going

This would have been a super easy install had it not been for the small area I had to work with. I had to use a wrench to remove the old valve which was the hardest time, otherswise this would have taken less than 15 mins to complete. Make sure to have a small bucket and a towel handy. Also, it allows you to choose how much water is filled with, just make sure to be sure of what you want since you’ll have to do the whole process if you want to change it. It’s quiet, the first night some one used it I thought it didn’t work but I just went in and tighten it a little more and never made the noise again. I haven’t checked my water bill I’m sure it’s help since again the bowl is now filled with less water.

Excited about a flush valve?

What can I say? The moment after I flushed the toilet after installing the Korky 528MP fill valve I let out a quiet, almost imperceptible giggle. I've been replacing flush valves in toilets for years. Not a big project, just a routine task of home ownership. I ALWAYS used Fluidmaster fill valves. Korky flaps, Fluidmaster fill valves. That's what I told myself. After having a Fluidmaster fill valve fail after six months, I thought I'd give the Korky a try. Their other parts have always worked well and have been high quality, so what's to lose, I thought. Absolutely nothing, it turns out. Compared to the Fluidmaster, the Korky valve is easier to install, easier to adjust and better performing. First the installation. Rather than having the float housed on the exterior like the Fluidmaster, Korky's float is internal and takes up much less space. That makes the valve much easier to position in the toilet where it can sometimes be difficult due to the location of the overflow tube and flush lever. Next, the adjustment. For proper performance, the Fluidmaster requires adjustment of both the float and toilet bowl fill. This is accomplished by adjusting two very fidgety devices. The float has a plastic screw that always feels like it is going to snap if I move too quickly. And the bowl fill adjustment is a cheap and imprecise thumb wheel attached to the fill tube that seems to have a mind of its own. The Korky, by contrast, requires no adjustment of the float. Simply line up the silver housing with the overflow tube and tighten. And the toilet bowl fill is adjusted by a simple and precise quarter-turn valve attached to fill valve itself. Much more accurate. Finally, the performance. The moment I flushed the Korky I was smitten. The valve let out a brief rush of water, then settled into a very quiet fill. No loud hissing like the Fluidmaster. Although I didn't time the two valves, I also believe the Korky fills the tank faster as well. It's hard to imagine something so basic bringing such joy. But sometimes that's what life is about: the simple pleasures. And that's what the Korky delivers.

Solid replacement Fill Valve for Mansfield Toilet

My old Plumbcraft Valve started to make the fog horn noises and needed replacement. Based upon the previous reviews decided to give the Korky Valve a try. It was easy to replace, easy to setup and has been working well for the last several weeks. Fills the tank quickly and not too noisy. My old Plumbcraft Fill Valve was a little more quiet before it started going bad, but so far am happy about the Korky performance.

A toilet tank valve? Well yes and it works well and is quieter than the original I replaced.

OK what can you say about a toilet tank valve? Well, we are on a pump in the country and part of our issue is that our well is 20 years old. The water lines and especially the toilet tank fill valves get clogged with small pieces of sand and lime rock that is coming loose inside the well and being pumped through the pipes. I have put a water filter system in the house now to stop it, but it clogged up several things before I could do it. These were one of those. So I bought these to replace the current slow, noisy ones that were clogged with grit. SO I replaced the old ones with these and these work great. Quieter, and fill quicker (maybe seems that way because they are not clogged) but they work really well. It is easy to do and took about 15 minutes total to drain the tank, remove and replace everything. Anyone can do it, its really simple!

Great for Toto toilet.

Have purchased 3 of these for toilets, 1 of another brand, and all these fill valves are easy to install. The only pain in the neck part of installing is if you have a Toto with a CT416 tank. You must remove the tank to get to the water supply line connector. These Toto toilets are sleek, no visible intestine looking bumps on sides, but this sleek look is a pain for maintenance. Two of the Korky are quieter than a 3rd one, not sure why, but they all work fine. I have hand tightened all my 4 replacement fill valves and no leaks ever. I know some videos say to tighten a 1/4 turn on connector, but I find gloves gives me a good tight grip and turning strength. Suggestion to make install of correct height perfect. Measure the new replacement against the old fill valve and adjust height before you get it in toilet. Same with measuring the rubber hose. Easy to cut hose to correct length before getting in toilet.

Easy, low cost

After years of service, the toilet filler started leaking, allowing a trickle of overflow to increase over time. Opening the lid and finding a Korky already in place, I decided to try another just based on cost and ease of installation. With no tools required, the replacement was quick and easy. I had to ponder the extension of the lower piece only briefly as it was slightly sticky initially. Additionally, as with all types of water related connections, I had a very small seeping drip from the plastic connection at the toiler bowl that was obvious from a tiny puddle under the toilet over hours -- loosening and retightening (but not too tight!) the plastic pieces stopped the leak. Everything works perfect now. Happy with the ease of replacement for the low cost!

Fast & quiet

Installed the 528MP yesterday, replacing about a 6-7 year old Fluidmaster. The 528MP fills the tank much quicker than the old valve. It seems to be louder (not objectionable) for about the first second, then is very quiet for the remainder of the fill. The installation was easy with simple to understand instructions. I did adjust the height twice to be "perfect", but don't really know it the adjustment is all that critical: was only off by about 1/4 inch. My BIG problem was removing the old valve. The plastic nut that held the old unit was so tight that I stripped it trying to get it off. I made sure I only hand tightened the new unit, and the new plastic nut is physical larger and should be easy to remove in the future.

Much Better Than the Original!

I bought this unit to replace the fill valve that came installed in the commode tanks of my new home. The originals were noticeably cheap in construction and cumbersome to adjust. The water level in the tanks was never quite right and the water flow itself seemed uneven. This Korky unit was very easy to install (I watched a video on YouTube just to be sure I prepared properly). Once the unit was in place, I was able to adjust an optimum tank water level with a simple twist of the shaft. I only had to make two adjustment corrections to get the water level where I wanted it. There's no messing around with chains or cock balls ... just the mentioned shaft adjustment. I noticed also that the flow of the water itself was now even and rapid. The unit operated so well that I replaced the fill valves in ALL of the commode tanks in my home with this same unit. This is an excellent product. I recommend its purchase!
