Fluidmaster 400CRP14 Fill Valve and 2-inch Flapper Repair Kit (Pack of 1)

First off, Amazon has the picture wrong on this. The 400CR is the newer version with the screw type float height adjuster..always, whereas the 400C can be the old (bar and clip adjuster) or new version because Fluidmaster reverted back to using just 400C some time after the design revision. I knew this when I ordered, but for those of you who care, there it is. I've had both the old and new and just prefer the newer design personally, but plumbers don't seem to care either way. They both function exactly the same way. This is by far the best designed, easiest to install and configure, and reliable fill valve available. I've installed it in each of my toilets over the years. It fills fast, fairly quietly and doesn't cause pipe hammer. I finally had to replace one (the older design) because it repeatedly started having issues. I'd had it in the toilet for at least 10 years anyway! First it started running, which was easily fixed with a cap flushing, but then water stopped flowing to the fill tube. The clog was down in the fill valve below the cap and did not stay fixed with a flushing, so I just decided to replace it. They only take a few minutes to replace and the cost is nominal. The flapper that comes with it is of good quality but I haven't used it. It can be installad on round or square fill tubes that have flapper posts on them. (A post ring for fill tube is not included. Looks like the picture of the black part of the flapper is wrong too. It does not have a fill tube ring. It is open ended just with hooks) My one toilet has a flapper with the timing cup on top of it and it's own drain seat insert that it's attached to (555CRP8, also made by Fluidmaster, 555C is the newest version) because the fill tube is too far from the drain and a standard offset on the flapper, as this has, wouldn't center and seal properly. The other toilet still has a firm gray one with a notched plastic "chain" that I installed separately years ago too. If they aint broke, I don't replace them! Flappers are the touchy part. In addition, fluidmaster provides excellent instructions for the DIYers like me, both in the package and on their website, including troubleshooting instructions. Top notch professional company. Highly recommended.

Easy to install and works well so far!

Fluidmaster Toilet Fill Valve is GREAT (5 stars) but Flapper is NO Good (3 stars). My 12 year old fill valve was not accurately filling the tank, we had constantly overflow - initially thought it was a flapper issue but then later realized that water in tank was flowing into the overflow valve. Then I knew that it was the fill valve that was bad. After replacing the fill valve no more problems. But the flapper didn't work because it has a notch not a hole, so whenever we flush, the the water current would blow flapper off from the holder. See the picture provided. I guess for certain toilet models it might work, but not mine. So I got another flapper that has a hole, and now it holds well. So all in all, fill valve is great, the instruction is also well written. It works much better than my old one (when it was new). So if you have a fill valve issue, just get Fill Valve separately. Easy to install, and works great! But don't get the Fill Valve & Flapper Repair Kit. If you have a flapper issue, get a separate flapper from your hardware store. Highly Recommended!

Thanks to the severe water pressure I have coming into my house, I have been forced to change out both of my toilet water regulators. Even though I have done this multiple times, this kit has great instructions in my opinion. I believe it would make an easy replacement for the average person. They seem to be of good quality, fit well and lower noise levels than the original ones. If I think about it, I’ll edit this as far as quality when they go out. As of now, they are going strong!

The area I live in has hard water. There are a lot of mineral deposits in the water which can, over time, create some plumbing issues. Our toilet was filling slower and slower and no matter what I tried, I could not resolve the restricted water flow. The old water fill valve system was a Fluidmaster and I was pleased with the value and performance. I ordered a new Fluidmaster 400CR. What most people do not realize is that your problem is with the fill part of the system, you do not need to replace the entire part. There is a white plastic part about ¾” wide that slips up and frees the bottom part of the value assembly. It takes a little twisting/pulling to get it off, but you then can just replace the top part – the part which actually controls the fill. To change just the operating part. Turn the water off, flush the toilet to drain the water from the tank. Reach under the assembly and move the white plastic part up. Pull the upper assembly off. Do the same with the new assembly. Put the new assembly over the old fill pipe. Push down the retaining ring. Reconnect the overflow hose. It takes less than a minute and there are no leaks. You do not need to worry about the supply line. If you are replacing a different assembly, you will need to replace the entire assembly. Turn the water off, place a catch bucket under the supply line input. Flush the toilet. Unscrew the assembly screw. Take out the old assembly and insert the new assembly. Tighten the new assembly in place. Reconnect the supply line. Turn the water on and check for leaks. This will take about 15 – 20 minutes. Great value, quick and easy installation.

Excellent. Absolutely worked perfect.

Lo pude poner fácilmente, ya incluye la alimentación y el flotador, y las piezas funcionan bien, también se puede ajustar para que sea economizador.

Works perfe t, super easy to follow instructions and works great. Could fill a bit faster maybe, but works so much better.

Took me about 15 min to install the new valve and get it back in service. Use this for the kids bath room. No more water hammer when the toilet is flushed. Kids are happy and I no longer hear a horse coming down the hall. Well worth the purchase. Very happy. Kids are happy as well.

Fit my 2 Eljer condo toilets. Flappers work well too!

The repair kit did its job – fixed my toilet without any issues. Very easy to install, and is quite adjustable. Instruction were also pretty clear. Great value.
