Adjusting height of fill valve when installed in tank

The 400 model fill valve must stand 3" taller than the overflow pipe for anti-siphon purposes. For all those that didn't read the instructions before placing your fill valve in the tank, here is a video that shows how to adjust the height of the fill valve while it is in the tank.

MOVE THE PLASTIC RING UP IF YOU CAN'T TWIST THE FILL VALVE!!! I was doing as this guy says and trying to twist the fill valve but it was way too tight and difficult to twist and I stopped once I heard a scary grinding sound. But once you move the plastic ring up, it'll untighten the fill valve and then you'll finally be able to adjust the height. This guy leaves this step out so don't miss it!

I am so proud of myself. There were a couple of mishaps. I didn't put the cap back onto the shaft securely and when I turned on the water, the water shot up all over the place including my head. Next mishap: when I adjusted the shaft, I didn't realize that I also was turning the large locknut under the tank. So water leaked all over the floor when I refilled the tank. However, I fixed all that and my toilet is working perfectly. As a 70-year-old woman, I love learning new things and saving money. Thank you.

Everything about this video was perfect EXCEPT, as some others have mentioned, you can change the height without taking the top parts off and twisting the shank! My Fluidmaster is one of the new ones that has an extra bowl fill attachment on it, and makes the twisting room almost non existant. I was looking at removing the valve from the toilet to change the height when I saw a comment from others in the comments about sliding the plastic lock UP on the shank. That was a game changer, as all I did was move that plastic lock washer UP on the tube, and that allowed me to just pull up on the top part to extend the height! I then puushed the lockwasher back down in place, tested the water height, and VIOLA, my toilet was fixed!! GREAT VIDEO, though, guys, and VERY easy to follow!

OMG!!! I can hardly believe it. Thank you thank you thank you!!! Thanks to you and all the other YouTube videos I've been watching this morning, I just fixed the toilet in my guest bathroom!! For five years I have been lamenting all the horribly slow and multiple flushes required to clear that toilet bowl. Eww. The constant cleaning, because even multiple flushes weren't complete. A couple of my guy friends attempted without success to adjust or repair it. So I've been living with it because I wasn't willing to spend my precious little money on an expensive plumber. Finally, and with determination, I spent nearly 2 hours early this morning researching how to fix a slow flush. I also watched videos like yours about a half dozen times until I "got it" and voila! My toilet finally works like a powerful new one! And it was so freaking simple (in hindsight of course). Your video was the best and I followed your instructions to a T. A heartfelt thanks very much to you and all the generous people like you who share information so that people like me can save potentially hundreds of dollars. Who'd a thunk it'd be that simple? Thank you thank you. - An Omaha woman who took initiative, employed the patience to learn and surprised the heck out of herself!

After spending an hour watching various videos to fix a continuous overflowing issue. I was ready to go out to Home Depot to replace the fill valve. Watching this informational video helped me understand that the fill valve height can be adjusted as well and saved me a trip. Thabnk you!

You Can Also, Drain Water in Tank, and Then at Bottom of Grey Tube, there is a 'Pressure Fitting' That You Can Lift Up On, and It Will Release the Lock. Then Just Pull Up to Desired Height, and Then When reached Desired Height, Push Pressure Fitting Back Down On Grey Tube Sleeve.

This Way You Don't Have to Disconnect Anything.

Thank you for the useful information. I tried adjusting the long screw on the float cup, but needed less water in the tank. It wasn't until I found this video that I figured out that the shaft needed to be rotated for major adjustment. Very helpful video indeed!

Thank you thank you thank you for a clear, to the point tutorial! I had replaced the fill valve myself and after not using the toilet for a day, discovered water leaking from the toilet handle. The fill valve wasn't high enough, my installation error. Did NOT want to remove it and start over. So happy I came across your video, it gave me the courage to attempt and fix it myself! 50 year old woman with no experience whatsoever.

Thank you so much for this. I tried the methods shown in three other videos before finding yours. This one worked. The difference, though, is that i couldn't get the top cap off. Had to just twist the shaft a quarter turn at a time, in increments, while alternating re-centering the top parts. Got the whole thing significantly lower, and now the tank doesn't overflow and leak through the flush lever hole. Beautiful. I'm 50-something and not a DIYer. Lived in NYC for 25 years, where the prevailing modus operandi is, "Call the Super!" But, now i'm in the suburbs.... Old dog, new trick.

I was a little upset because of the shorter valve and water is not filling up. Now because of your video I know how to adjust the valve. Thank you.

I've watched a few videos on YT. Yours was the one that works. My toilet water keeps running. Thanks for the thorough but short and sweet.

[jessiska]

Thanks for this :D My toilet leaked into my downstairs neighbor bathroom fan because the person who set it up made it fill over the line by a lot. 4 clockwise turn and it's flushing right every time on the line. I am so grateful for all those kind of videos people are taking the time to post that are so useful. <3

Thanks So Much-IT WORKED!!!! I actually fixed it! Im a 62 year old woman that just bought a house.

Thank you!! Every video I found was just to lower the float, not the entire thing and my float was as low as it could go. So helpful.

Thank you very helpfull video. Girlfriend had one installed and had to do 2 or 3 flushes most of the time. I adjusted the fine adjust screw all the up but still had to do multiple flushes. Water level in the tank was about 2" lower than the previous valve. Was about to swap it out with the old style before I ran across your video. Thanks again!

[BFarmer]

Thank you very much for this! I had a new floating cup assembly installed in my apartment today, and couldn't figure out why the tank wasn't getting enough water to properly flush. Glad it was such an easy fix. I'm not the handiest person in the world, to say the least.

Thank you so much for such informative video.

My old toilet is 20+ years old and I was super frustrated that all the videos I watched in the last hour were talking about “adjusting the screw” attached to the fill valve. Guess what? There isn’t one on mine. After seriously considering to replace the fill valve, I landed on your video and it only took 10 mins to fix and adjust the fill valve height.

Thank you again for saving me and my family’s sanity😊

Thank you! Easier to understand and follow than the manufacturer instructions.

[georgemantoan]

I watched this twice as well as another video. This was very helpful. The only thing missing from this it that you must/should, raise the clear plastic guard at the bottom of the gray shaft which allows the adjustment. Maybe I do not have the hand strength to twist the shaft to decrease the height. Aside from that, it worked like a charm to adjust my water level. Thank you.
