Yes, the 528MCM Korky QuietFILL MaxPERFORMANCE Fill Valve is 100% serviceable while installed in the toilet. In the event you need to service your fill valve, please follow the instructions below, or call our customer service team at 1-800-528-3553 for detailed, step-by-step instructions for servicing your fill valve. Turn off water supply. Flush toilet. Remove the refill tube and fill valve cover. Remove the float by gently squeezing the float arms inward and lifting up. While holding the valve body with one hand, twist the cap 1/8 turn counterclockwise and remove. Rinse the cap under warm water and ensure there are no cracks or damage to the red rubber. Do not remove the red seal. If the red rubber diaphragm inside the cap is worn or punctured, a replacement cap assembly is required (Korky part number: R528CM and available at Home Depot: #160-959). Lift out the center tube. At the bottom of the center tube, twist and pull out the white plastic tab. Remove strainer and clean by rinsing under warm water. Reassemble valve by reversing the above procedure. After reattaching float, tap the top of the float to ensure float moves freely and does not make contact with the sidewalls of the float chamber. Put on cover and refill tube. Then turn on water supply and you are good to go! Read Less

My current valve works fine in that it fills quietly enough. But it seems that it stops abruptly and my pipes in the basement bang. Wondering if this would fix that.

Rated 4.5 out of 5 by 76 reviewers.
Rated 5.0 out of 5.0 by Works on my strange toilet Have a dual flush toilet from Whithause. Was afraid it wouldn't work, had set aside a half day to install yet only took 20 min. No tools. Works great. Works quietly. Very satisfied. July 24, 2016
Rated 5.0 out of 5.0 by Much Easier To Install Than It Looks The valve that came on our American Standard toilet had begun to make very loud noises that replacing the seal didn't fix. We have fairly high water pressure and it seems like it wasn't able to hold up over time. I opted for this replacement valve over other options specifically for that reason. The package makes this look like a very difficult installation, much more so than others I have installed previously. Perhaps that is just because of all the components that are included to make it universally compatible with many different toilets. I found that our toilet actually only required the valve itself, the preinstalled adjustable diverter with tube and clip, and the nut to attach the valve to the tank. There were four other pieces that were not used. A great deal of the instructions are devoted to adjusting the valve to the proper height and water level, but for our toilet it was immediately apparent that the shortest setting was the right one, so I immediately skipped to screwing the nut to the bottom of the valve to attach and seal it in the tank. I cut the black tube to the proper length, inserted the clip and attached it to the overflow tube, set the diverter adjustment to about halfway open, reconnected the water supply and turned it on. By luck the diverter was at the perfect setting for the right amount of water to fill the bowl, and I was done in under 10 minutes after removing the old valve. The clip fits very tightly inside the black tube, but I found heating the tube slightly made inserting the metal clip MUCH easier. The hardest part was definitely getting the original valve out, as access to the nut on the underside of the tank is nearly impossible on this particular toilet. Getting the new valve tightened was much easier, but still one of the more difficult parts of the installation. Once installed, the tank and bowl fill at least as quickly as with the original valve, but much more quietly. The biggest difference I notice is when the tank is full and the water shuts off, it does so more gradually with a bit of high pitched noise for about the last second before the flush cycle is complete. Not really loud or a nuisance, just something that I notice is different than the sound I was used to. June 6, 2016
Rated 5.0 out of 5.0 by PERFECT FIT --- PERFECT FLUSH ---PERFECT FILL Installation of the Quietfill platinum fill valve was very simple and very straight forward. The only tool that was required was an adjustable wrench. The total install took less than 15 minutes. For me, this fill valve replaced the old style ballcock. The design is innovative and as you can see by the pictures below, it fill fit in any size toilet. It takes up much less space than the older design. Great unit!!! May 1, 2016
Rated 5.0 out of 5.0 by Great so far I tried to go with what I had before, but they're junk now. I seen the reviews and then took this home. Really easy to install, but different method of doing the float. Long story short, I adjusted it after installing and flushing the tank until I got the water level where I want it. It says it quite, not sure what planet they come from, but sounded the same to me. WITH the only different was if I turned the flow up on the fill valve, then it made a lot of noise. Takes a while to fill but that would only effect those double flushers. I've had it installed about a week now without any issues. July 19, 2016
Rated 4.0 out of 5.0 by Fast and easy! Although it is all plastic, it seems to be sturdy, and the adjustability - making it very universal - is a plus. August 16, 2016
Rated 4.0 out of 5.0 by Quick easy fix! On shelf and easy 10 minute install. Would buy again if needed. August 16, 2016
Rated 4.0 out of 5.0 by the price is good for good product easy peezy install bought this product installed it in 30 min adjustable water flow for even quite flush August 7, 2016
Rated 4.0 out of 5.0 by Pretty quiet The instructions are pretty bad, but the fill functions well and the water cutoff was positive. The length adjustments seemed to work ok, but again the instructions on how to move the length were poor. This seems to be a much better fill valve than the float slider valves which stop working as the slide builds up sediment along it. July 19, 2016
