I just did this exact repair no more than 10 mins after upload. the toilet has been having issues for the past 3 years and since it is a toilet no one uses it was easier to turn off the water until today. It was a great walkthrough tutorial. Thanks for the confidence boost.

Jeff…. Thank you so much for this easy to follow video. My toilet has been making this noise for over a year…. OVER A YEAR!! I assumed my hubby was never going to call the plumber so I took matters into my own hands. Thanks to your video.. my toilet is finally quiet. The only issue I had was that apparently a very strong man had tightened the plastic locknut God knows how many years ago, and I just couldn’t twist it off. I decided to try twisting the old fill valve inside the tank to see if it would loosen the locknut that way, and it did. Once it was loose I was able to twist the locknut off without a problem. This time it was twisted back on by my women hands so it should be easier to take off if needed next time. 🤣 Thanks again for saving me money by teaching me how to do it myself. A lot of pride comes with doing things yourself. Oh… and my husband is singing me praises!! 😂🤣

I watched you video where you recommended replacing the entire fill valve instead of just the seal. I went cheap and just bought the $3 seal. After installing the seal, the whistling stopped, but the fill valve never closed. Another trip to the store to pick up the fill valve as you recommended finally got my commode working quietly.

THANK YOU! You just saved me more than $60 for a service call alone. Got the part this morning and fixed in less than 5 minutes. Appreciate the video!

No way! I thought I was the only person on earth whose toilet made that noise. Thanks Jeff for another helpful video. Take care.

Although I didn’t replace the pump, this video did help me. I didn’t realize there was a removable, rubber seal on the inside. I have hard water in my home and suspected there may be buildup of minerals, which I was right. I used soap and an old toothbrush to clean off the mineral deposits, put it back together, and the noise was gone. I know a new unit is only $15, but money saved is money saved. I certainly recommend checking the seal since it only takes a few minutes.

Just fixed my toilet using this video and the process couldn’t have been easier. Thanks for the help!

Finally someone that actually shows the noise the toilet makes rather than talk about it then fix it.
Getting ready to fix mine and had to watch 5 videos to hear one that made the exact sound that mine made. 😂

I should have listened to your advice the first time I watched this video, sure enough the $2 gasket didn’t fix it. Ordered the entire thing from Amazon and was an easy fix. Thank you, just subscribed!

We've had the squealing issue with our toilet for over a year now. We eventually stopped using the bathroom because we thought there was a serious problem with the toilet. I was about to finally call a plumber when I decided to Google the issue to see if it was potentially a simple fix. Your video was the first one I came across. I immediately ordered the $15 replacement part on Amazon and got it in today. I am the WORST at home renovations, but with your help this took me only 10-15 minutes to fix!! Thank you so much for saving me probably over $100 on hiring someone to fix such an easy problem

Just fixed my toilet yesterday finally with the help of this video. Thank you! My replacement valve is a 400A and the old one was M31718. Both by Fluidmaster. The 400A has a plastic pipe and the other one had a metal pipe. The maximum height of the 400A valve was at the three inch mark above the overflow pipe. Increasing the height of the main valve increases the water going into the tank. From there, the secondary valve fine tunes the water level up or down. If you use the secondary valve, the best way to test it is to flush the toilet next. Just adding a little water through the secondary valve does not necessarily reflect exactly where the level will be on subsequent flushes.

Thank you!!! Was able to fix our toilet ourselves with this video! You are the best!!! Took us less than 15 minutes!

[d.t.]

Watched your video 8 times while doing the repair, still like your video due to what my other comment stated.
Took me 35 minutes to repair the toilet, just going back and making sure everything was tightened.
Only difference is that i had to use a pair of pliers on the gasket at the bottom and i did use my Shop Vac, but everything else went perfectly. 😁
Thank you for this video and i am now a committed subscriber. 😎👍🏾

Thank you!!! I don’t know anything about plumbing except that it’s expensive to call the plumber. By following your instructions, I just fixed my squealing toilet! I thank you, my children thank you, and my sanity thanks you!

[algamboa]

I usually don’t comment on YT videos but am appreciative of this thorough, explicative repair guide.

[rlw]

Great job buddy. It solved the whining noise I was hearing, and I also found out after doing the 3" measurement between the overflow tube and the top of the fluid master that the old the height was way too short. I fixed all that and it runs better than it ever has. Thank you.

[zakshellabarger]

Did this step by step and worked like a charm! Thank you!

[brianfauss]

Amazing instructions. I screw up every DIY project I've ever tried. But I watched this video twice, walked into HD and got the part, and the whole repair worked like a charm. Thanks!

[MrSIMURDIERA]

Thank you! We’ve been dealing with this problem for over a year. I even tried giving the valve a little bit of oil in hopes for that horrible noise to go away with no avail, nice and easy tutorial!
