Easy to install, works great.

I have never done any sort of plumbing repair work ever. I opened this up, turned off the water to my toilet, dropped some towels behind the toilet, and got to work. It was super easy to install, the instructions are well written, and my toilet is quieter now. All around a perfect product. I have a few points that I'd like to make about the instructions. The instructions say that you'll need a sponge and some scissors. I never needed the scissors. To handle the remaining water in the tank, I used the towels. Equipment that I used that wasn't mentioned in the instructions: Vice Grips. They come in handy during this project. If the bolts on your toilet are too tight to twist off with your hands, you'll need something like vice grips to take those bolts on and off. Even if you aren't repairing a toilet, get yourself some vice grips anyway. They are useful around the house. A mirror. I used a mirror with a stand so that I can see the bottom of the toilet. I used my wife's vanity mirror. It worked great! (Don't tell her.) Anyway, I didn't time myself on this repair job, but it was easily less than an hour, and (mind you) I have no experience with this sort of thing.

Easy to install, even for a novice.

It's never a good day when you're having to replace the fill valves in your toilets, but this model makes the job a lot less painful. The included instructions are easy to follow, and I had no trouble getting this to seal properly in my toilet's tank. The screw for adjusting the float height takes some effort to twist, but I suppose that's being too loose and turning on its own! I especially appreciate that the instructions explain very clearly how to adjust things like the level of water in the tank and the toilet bowl. In terms of performance, no issues here. The flow does seem a little quicker with this valve than with my previous one, resulting in a shorter tank refill time. I will definitely purchase another one of these when the fill valves in my other toilets need replacing.

I Don't Know About "Quietest", But It Certainly Refills Fast!

This model is a definite improvement upon the classic Fluidmaster design. Though not overly noisy, it doesn't sound noticeably quieter than other fill valves. Where this valve really excels is the rapid refill time. Timing from when I pull the flush handle, it takes just 25 seconds until the valve shuts off. I didn't time my old Fluidmaster valve, but twice as fast would not be an exaggeration — it's the fastest refilling time I've ever seen on a regular 1.6 GPF tank-style toilet. (I suppose you could also say that makes it the quietest, because any noise lasts for such a short time.) IMPORTANT — Take the time to adjust the refill tube control slider. The idea is for the toilet bowl to reach its proper fill level at exactly the same time the tank is filled. If the toilet bowl fills before the tank fill valve shuts off you will waste water. With a bit of trial end error you'll find the perfect position for the slider. Fortunately, it won't take long to do this, because the tank refills so fast! The Fluidmaster 400ARHR High Performance Toilet Fill Valve is an ideal replacement for any standard toilet fill valve. It's well designed, inexpensive, easy to install, works great, and saves water. I might even call it "perfect".

I could easily replace my old toilet water valve simple following the ...

I recently moved out of my parents house and living alone. As a woman who have zero experience w fixing the toilet water, I could easily replace my old toilet water valve simple following the the instruction on the package. I am glad I took the risk buying it and installing it myself.

These are great for a couple of reasons

I think these are great for a couple of reasons. 1. They are much easier to set up than the old "bend the rod to set the level" type fill valves. and 2. Once installed, they can be very easily replaced (if you need to in a few years) by just pulling the valve assembly and grey tube off of the black tube and just pushing the new one onto your black tube from the previous installation of the same brand and model. There is no need to drain the tank completely or fuss with getting the washers to seal on the tank. I don't recommend the water saver version of this because they tend to stick and, ironically, use even more water as they run and run and run.

Took care of jackhammer sound, easy install

The old one was producing a jackhammer sound that went on for a minute or so. Tried cleaning it out but was unable to resolve the problem. This was easy to install and now normal flushing operations have resumed. I paid a little more for this unit than the standard one, but could not figure out how the roller clamp works so I left that out for now. The directions said to make adjustments using the numbers printed on the part, but there's no lines or marks to line up to the numbers, so I'm not clear at all what those numbers are for, or this part for that matter. Something to do with balancing the water level between the bowl and tank. But regardless, we have a working toilet again and didn't have to pay a plumber.

Super Easy to Install and Works Flawlessly

I had never replaced a toilet valve until I bought this. But I figured that since it was broke, what's the worst that could happen. Luckily for me, this is pretty much fool proof. Just follow the directions and 15-30 minutes later (or less if you've done this before), you have a perfectly functioning toilet. I installed this a couple months ago and I feel confident that if it hasn't messed up yet, then it won't need to be replaced for years. For the record, I have no idea how much water this was using compared to the old one of the same brand because we just moved into this house before replacing. The noise and fill time seems to be "normal" if that's a worry

A minor upgrade that works as well as the 400A, maybe better for some folks

I usually purchase a 400A but I thought I would give this newer model a try. It's every bit as good as the 400A. It has excellent instructions for those who are new to changing a fill valve. The instructions are expanded over the 400A's to include using with 3" and Duo Flush valves in addition to the more traditional 2" valve. .As others have said, it is the unit is the same as the 400A with the exception of the roller clamp and hose clamps on the refill tube as well as a spiffy-looking blue cap replacing the black cap. If the internals have changed I can't tell, but it does still use the 242 replacement seal in case you are wondering. The main benefit of this valve is you can adjust the amount of water that goes into the overflow pipe. This is the water that refills the bowl after a flush. If you let too much water flow you will waste water. You need only enough water to fill the bowl. If you don't allow enough water the toiler may not flush correctly the next use. I found that I had to set the clamp down a notch to properly fill my bowl. Previously I was probably only wasting a few ounces of water but why waste if you don't have to? The 400A is a bit cheaper but this is a very worthy alternative in my opinion. This one does seem to fill a bit more quickly and slightly quieter than the replaced unit, hower the replaced one may have been a bit clogged. We have super hard water where I live and these fill valves have a rough life and plug up regularly and need cleaning out to work well again.

If You Are Using Anything Else You Are Not Using The Best, Easy To Install And Inexpensive UPDATE: Jul 10 2018

UPDATE 10 July: Well I just bought another one to replace one I had for several years in my guest bathroom, the amount of rust looking silt at the bottom on a tank of "clean" water takes away any wonder why they don't last forever (and why I drink filtered/bottled water). The installation was simple as always and trouble free. I have learned over the years that putting on some work gloves and tightening the large plastic nut at the connection next to the tank results in less problems because with gloves you can tighten it very snugly without over-tightening it as you can with a wrench (which can actually cause a leak). The end attached to the water supply obviously does required a wrench but again, don't overdo it. What is there to say, basically you use Fluidmaster or you live to regret it. These things are not programmed to wear out in a few years but chemicals and mineral deposits and such make them last about a minimum of 3-5 years or as many as 7 depending on your water conditions and they are simple to replace and easy to adjust. I tried a few other brands over the years and have always come back to these for simplicity of installation and quality of workmanship. Once they start going bad you can solve some problems by flushing them out (instructions for doing this are in the box) but they are so inexpensive and easy to install it is usually just as easy to replace it. Pretty much finished trying other brands so this is what I buy every time and I keep 1 in my closet for emergencies and replace it when I have to use it. Always have one on hand these days. NOTE/WARNING: Almost all of the problems I have read about in other reviews come down to 3 things because after 26 years, 2 houses and 6 toilets these things do NOT fail in less than 3-5 years (time depending on your water and a variety of random things): Make SURE your float arm or the arm attached to your handle is not binding on anything when you put the cover on If they have been working on water lines in your area, chances are that some trash has been sent down the line that can stop/slow this valve (the flushing procedure is in the box that may help this) Using almost ANY "drop in" type cleaner will shorten the life of this or any other flush valve, don't use them! There have been people asking why this one and not the 400A, I have attached a chart to show what you are paying for with those few dollars NOTE: If you wish to reduce your chances of a leak, turn your water off for the house and not the supply line at the toilet. These valves have been sitting there usually for years and when you turn the water off and then back on many times they WILL leak at least for a few hours or more, if you turn the water supply off outside you will avoid this possible problem. If the toilet water supply valve has been used in the recent past without problem this can be ignored.
