Rated 5.0 out of 5.0 by HonRyte A good easy fix.
This is a simple part that can save you time and money. Instead of draining the toilet tank and removing the water feed line you need only to change the Replacement Seal on top of the water valve. I must admit that the procedure requires some understanding of toilet water fill valves.

Lucky that I have #400A so parts are available if replacement are required. My first failure in the past 20+ of using this valve in a all my tanks.

I wasn't sure I had a Fluidmaster 400A because it had a different number molded on the cap. But it looked like the 400A in the picture and the seal looked like the #242. So, for just over $2.00 I got our toilet working perfectly once again. It was an easy fix following the instructions on the Fluidmaster website.

Rated 1.0 out of 5.0 by PWu Not fit for older Fluidmaster model #200
For older Fluidmaster model, this is not replacement for Fluidmaster model 200. If you hold it up to Fluidmaster's 242 seal you can see the difference in thickness. Save yourself time and money and find the actual replacement seal, Fluidmaster 242. Or you need Fluidmaster 350 Fill Valve Cap to replace Fluidmaster #200.

Rated 5.0 out of 5.0 by Kacey Very easy to install
My toilet was very slow to fill, so I watched a youtube video to get an idea of what might be wrong. I followed the instructions on how to remove the top of the Flushmaster fill valve and checked the seal. Sure enough, it had a hole in it. The installation of the replacement seal was a breeze, and the toilet is back to normal. I can't rate quality or value, yet, because I just replaced the seal 15 minutes ago. So far, so good!

Rated 5.0 out of 5.0 by James Great Toilet Fix wish they advertised this better
As preventative maintenance I just change this part about every 2-3 years on all my toilets. I didn't know this was the only rubber seal inside a fludmaster fill valve until I did some research. These wear out from chlorine in the water so expect to replace them every few years. I also flush out the cap when I change this and a few times I've gotten small rocks inside the cap. I have a extra whole house filter on my water line too. Also I showed this to my uncle since he's a pretty handy guy and he didn't know this is why fluidmasters won't turn off. After figuring this out I haven't switched out a fluidmaster assembly in over 5 years but I've put in probably 20 of these washers(showed it to friends and family)

This is a fairly easy fix for a non-handywoman like me. Only wish that Home Depot went back to selling these in multiple units in the little bag, like they used to. I have 5 toilets in my house, and once 1 of these needs to be replaced, it's not long after that they all start going. The bag of these saved time and money.

Rated 5.0 out of 5.0 by TCVAN Easy install for HydroClean fill valves
This also fits HydroClean fill valves. Turn the water off, unscrew the water level regulator on the side of the fill valve, press down a bit on top of the unit and turn counter-clockwise, remove top, replace the seal. Next hold unit over top and screw the water level regulator in a bit, place the top back on top of the unit, press down a bit and turn clock-wise to re-engage. Adjust the water level regulator, turn the water back on , and test.
