Easy Mansfield Toilet Flush Valve Gasket Repair, Replace Seal, Handle Fix 

Very helpful. I had to replace the gasket and it was still leaking. After watching the video, I realized there is a groove the gasket needs to seat in. Worked like a charm! Thank you for taking the time to make the video.

I got 100% of the information I needed in less than 4 minutes. Saved my day. Thank you sir

I was watching another video, in which many men gave thanks for a thorough replacement tutorial. The thing is that everything has to be taken apart! It was a huge & messy job. Your video was a simple shortcut that went straight to the problem, and I'm very thankful for it. Why take apart everything and risk breaking tight seals, to only have to reseal and check for leaks? Leave all the seals intact, and just go to the root of the problem. Unscrew the top, replace the one gasket that's damaged, recap, job done! Ingenious!!!

“It fits loose” are the 3 words that saved my sanity. Thanks SO much for your time and effort producing this video!

Dang that second groove causes some head scratching. Watched your video and then noticed the first groove. Your comment that it should be a little loose helped as well to know the first groove is indeed the right spot. Thanks, no more leaks!

I never thought watching a video to fix my toilet could be such a delight. Thank you so much for your kind, thorough, visual explanation of this. I will absolutely be coming back here for future needs!

This guy- the unsung heroes of the world. Thank you!!

Cool guy. You won't find someone like this at a Home Depot, etc... damn shame. Real men like this are a treasure.

Mr Hardware: your video is the only fix-it video on RU-vid that shows the important of The Groove. I was doing it all wrong - with mixed results. Thank thank you THANK YOU!!

That worked alright. Just lowered the water level in the toilet as you instructed and no more double flush. Thanks!

Thank You One of the Best Fix its on Utube - Direct and to the Point ! Going to try didnt know the plunger unscrews or that there was a groove for the gasket . Great Video Thank You

My comment is the same as Todd below. You saved incredible frustration by this demonstration of where to replace the gasket. Thank you.

Thank you for the easy to follow video. Changed it in less than 5 mins.

My mother has a Mansfield toilet with the exact problem you mentioned. I replaced that gasket today for $3 from Home Depot. It worked perfectly. Thanks a million for the perfect solution. I will be watching and liking all your videos.

I had an issue with the toilet being hard to flush. So I watched a video on how to replace the flush valve, and just felt that taking the entire tank off to make the repair was a bit much for some reason. But I went to Home Depot and bought a new flush valve and handle anyway. Well, after further inspection, I noticed that the flush valve was getting stuck in the orange gasket, because it had worn a groove around the sides of it. So after watching this video, I purchased and installed a new orange gasket, and it works like new now. So thanks for the vid. It was very helpful.

Almost a month ago now where I live we had temperatures plummit to averaging -35° F without windchill and the septic line in my mom's home froze, backing up all the way to her bathroom. I had to rip out the floor, toilet, put new flooring in, and replace all the angle valves for the water shut offs in the bathroom. All of that was a war in itself. I'm a single mom who helps to take care of my mom, kids, pets, etc, and not a carpenter or plumber! When it came to reinstallation of the toilet, I was so happy everything else was out of the way and done, til I realized I had no idea how to reassemble the hardware in the toilet tank. It took me hours to find a video like this one! I didn't know the brand, model, or anything of the parts I had. Previous parts were broken, missing, and scattered from frantically ripping out everything in the bathroom including the flooring when the blackwater backed up into the house. I didn't even know what part was called what, just been learning how to do repairs as I find the things that need repairing. I thought I'd managed to put the toilet flush and fill valves on correctly, but the flush valve was leaking. Couldn't figure out why because I couldn't even find a video or diagram of the flush valve up close. Now I know it's that rubber gasket/washer piece. Thanks for the vid 😁

Thank you Mr. Hardware! After 4 other videos from others failed to help me, your video showed how to replace the gasket by unscrewing the top! Other videos didnt show that! Success!

I was dragging my feet on fixing our toilet this weekend. I watched this video and fix my toilet in about two minutes! Thanks for posting this. Very helpful!

Thank you! The top groove part was exactly the step I needed. I VERY MUCH appreciate you taking the time to make this video, so helpful.

Short, sweet, simple, and straight to the problem. Excellent video. Thank you so very much!

I have replaced my gaskets in the past, but today I couldn't get a seal good enough to stop the leaking. I looked at your video again and realized that while I could get the gasket to rotate, I was having to use too much effort. When I found a setting where it turned freely it provided a solid seal. Thanks!

Man, I went to the store got the toilet repair kit, and was getting ready for the ordeal of replacing everything... Then I saw your video. Per your comments, I took the gasket out, cleaned all the deposits, and re-installed. Now I have to go back to the store to return the kit. THANK YOU THANK YOU! Quickest fix ever. :) I am a happy camper.

Holy Moly, thank you so much for this, mine was sticking, and you had to manually pull the valve up with your hands.

Thank you Mr Hardware!! I fought with the gasket for about 45 minutes before I realized I was putting it too low. Your video made it so clear where exactly it needed to be placed. Thank you so much!

This saved my life! Thank you for the clarification. I was about to take apart entire tank for this ring repair.

Thanks a lot. What you showed at 2.22 solved my problem. I didn't know there was grove there. So the washer didn't fit right and the thing kept leaking. Light bulb went on after you mentioned about the grove. Thanks a lot.

Sooo, I ended up removing the tank, lol. Wish I would have watched this video first, but actually removing the flushing valve was extra work but made it a lot easier to access the groove and gasket. Was about 15-20 minutes extra work, but Im glad I did so. Thanks for the helpful video. Yep, my gasket was stretched out quite a bit and qouldnt even sit evenly in the groove. Thanks again!

Thank you for your video. I struggle with making repairs but the cost of getting it done professionally makes the struggle necessary. I would have bought the handle with the plastic lever because it was for Mansfield but I tried the metal one and you're right, I needed to bend it. Also the tip about unscrewing the cap made the job easier to get in on the groove! Thank you! Subscribed! Videos give me the confidence to try it myself!

Perfectly clear explanation of this toilet design. Saved me lots os time and Money!!! Thank you

Very helpful! I’m not used to this plunger style of valve, so you really saved my day! (And you can’t beat that northern midwestern accent! 😄 I’m from California but lived in Chicago for 10 yrs.)

Thank you soooo much for this!! Had a running toilet for a month and didn't want to scrape up money to pay a plumber!! Problem solved! ❤

Thank you Mr. Hardware!!!! The gasket had dislodged, but I didn't know where it goes. Thanks for explaining how to disassemble the unit and replace the gasket on the top groove. Job done with the existing gasket, but I will be getting a new one as toilet is over 10yrs old.

Needed to know what gasket to buy and it was clear in the first moments of the video. Much appreciated!!

Great video; it answered questions I didn't know I had. I should have watched it before trying to fix the lever the first time. I had never seen a mechanism without a chain before. Since the house is 7 years old, I will go buy new levers and seals for each of the toilets. Also, a critical note is that the gasket rotates freely when it is in the top groove. If it doesn't turn easily it is in wrong and pinched. I watched the video and it took about two minutes to make the repair. Two minutes because the gasket was not moving freely in the groove the first time.

Thank you! All the other videos I found wanted me to take the whole tank apart. I found this video and had my toilet fixed in 5 minutes. Thanks for making this, and thanks for the easy to follow instructions.

Very helpful to say the least. I had never come cross a Mansfield toilet before. This video showed me exactly what to do and I fixed the leaking gasket in about 3 minutes.

Mr Blare.... Thanks a bunch... I ended up putting two seals on to get my toilet to seal... One below the slot and one in the slot.. Somehow the one in the slot needed a little support underneath it... I have a house in Troy Michigan... but I'm living and working in Memphis.... so all the way from Memphis to Sterling heights... thanks...! If only I knew how to give you two thumbs up your video was very clear and specific thank you.

thank youuuuuuuu!! I was replacing the gasket to the plunger, not the base. you are a life safer, almost took my whole tank off to replace all the guts!

2:25 shows where seal should be in the groove, very important. Other videos just say place in groove but do not show where exactly for this key step. Thanks!

Thank you very much. My Plumber quoted $400 to $900 to fix the leak.(SMH) Saying the Toilet needed to be replaced. After watching your video I fixed it myself. Thank you very much

You sir are a life saver. I was getting ready to replace the entire valve which requires taking off the tank. I think the chain got underneath this gasket and pulled it out of the groove. Glad I found your channel!!

Excellent video. I did not know that you could unscrew the top of the flush valve. I took my whole tank off to replace the entire flush valve when all I needed to do was replace the gasket.

Thanks a bunch! Was about to removed the tank and your video saved me lots of time. Replaced gasket and fixed. You are awesome for posting this!!!

So very helpful! THANK YOU! Ours is from 1998 & a bit different. The toilet handle is a push button located on the side of the tank. It's attached w/a pull chain & there's not much of a rod. Looks like that'll be next to go. The house was built by a builder for his daughter as a 1st home until she got married. We're finding a lot of lots of things were mixed & matched throughout. Thank God for folks like you helping us through our 1st home! Be well!

This was extraordinarily helpful. Thank you from Michigan!

Worked... After months of trying to put the seal on (and countless unhelpful videos) I watched yours and I can now sleep without hearing the water running . Thank you for the comparison from old to new it made the difference.

Would like to add with the others that you’re a life saver! Replaced a bunch of old Mansfield parts over the weekend and greatly appreciate the thoroughness of your videos. I know nothing about plumbing and learned so much about this unit from you. Subscribed. Thank you!!

Second time I’ve had to do this process in about two years for a different toilet. Was looking for my “friend is suspenders” again to guide me through it. Ten minutes and one part, we are back in business. Thank you!!!

72 YO widow and was able to replace the gasket. The biggest problem was finding the right sized gasket. Thank you!

Spot on! THANK YOU! I had the "really hard to flush" issue, which you pointed out to another commenter is the red gasket sticking, and that replacing the gasket would fix the flushng issue. And it did!

So helpful - after buying way more parts and kits than I needed, I tried just replacing the gasket and it worked a charm. Now I'm going to keep a couple on hand for the other toilets so I won't be wasting water in future.

OMG! I can't believe it by replacing simply the gasket and not the whole flush valve will solve my problem, you gave me great hint on how to replace gasket only without spending time and effort on a lengthy process of replacing whole flushing valve👌....Thank you. Next round of beer on me Mr Hardware😇.

You saved me so much money!! Money saved is food on the table here! Thank you!!!

Mr. Hardware: Thank you. You have just saved me a lot to time and frustration. Thank you. 🤩

sir your awesome ..... the only one person who showed this model to your video was 5 years back ,,, dam even last two years there are many videos by different people I don't see non of them doing the videos of this model thank you so much for your explanation

Very informative and straight forward tutorial. You just prevented a desperate woman from going insane over her toilet flushing every few minutes! Fixed the issue in less than 5 min, thank you!!

Saved my bacon. Thanks for the video! Couldn’t figure it out until I watched this one.

Excellent! I bought the whole Mansfield flusher kit and just used the gasket! Still so much cheaper the hiring someone to come take a look! Thanks so much, the old gasket was falling apart!

Thank you this fixed my issue for only $2.99 🙂 after suffering for months with a running toliet.

I had replaced one of these before and had a problem where it kept leaking. A year later and I had to replace another one on a different toilet. When I did it was still running frequently. I decided to search for the answer and found this. Thanks for showing the gasket has to go in that top grove. That did the trick!

Thank you. I had all but given up and ready to call the plumber. Then I watched your video and saw that I replaced the gasket in the lower and not the upper grove. No more water running!

Thank you for this video! Although I completely missed the part about you saying to put the gasket in the top groove. My Mansfield toilet has been running for a while, and I finally tried to fix the problem. I have 0 handyman/DYI skills whatsoever. This video made it look easy. Although I got really frustrated when I made the problem worse but I re-watched your video and realized I put it in the bottom groove instead of the top. After I re-watched your video I realized I missed that part, put it in the right groove, and my toilet now works perfectly, and does not run at all anymore. Thank you.

God bless and thank u i cried thinking i had to get a new toilet cause this happened to me making my bill almost $1400 i don't know why they warn us ahead of time but you helped me save $80 i don't have thank you so much ❤

Thank you for your help. I felt so good "fixing" my toilet by myself. Flushes with ease now.

Thanks brotha, I actually purchased the red and black gasket not sure of which I had to replace and I was staring inside the tank wondering if I had to take the whole damn thing out then I watched you do it, put my big boy pants on…went back in and got er done in a minute 🤗 So I came back to give thanks where thanks is do 👍🏻🤛🏻🤙🏻

Brilliant video! I had been searching forever trying to find out what type Flush valve I had because it didn't have a flapper like in every other video. And to boot, I was wondering why I could never find a flush handle long enough when I replace it awhile ago - ha, now I know!

Gilbert's Hardware in St Clair Shores, Michigan is legendary. Thanks for the easy video.

You explained this so well! I had never even heard of a Mansfield until I had to replace this gasket. Always wondered why this toilet’s valve looked different.

Great video and explanation - I knew it was the drain gasket, but couldn't figure out how to get the tower out to access the gasket - presto - didn't realize it unscrewed ....... thanks for doing this ........ nice job

Thank you. Your video saved me so much money. I bought the gasket at Home Depot for less than $3.00. Very easy to repair and toilet is working just fine.

A great example of how to do a good video. Tons of good clear information. No BS. I love it.

This helped me figure out how to get the moving part into a position where I could insert a new flush lever into the loop on the moving part. Thanks!

Super informative. I love trying to fix problems before calling professionals. You helped me save a few hundred bucks!

You’re dope bringing this knowledge to people who have no idea what the heck they’re doing outside a computer lab. Love it! 💜

Thank you. This is something I would go to my dad for but unfortunately he's passed away a few years ago. I appreciate the information.

I seriously can't thank you enough for this video. You saved me a boat load of money and I really appreciate you....

Thank you so much for this video. I thought the only way you could replace that gasket was by disassembling the tank and removing the valve!! This saves me so much time. ❤❤❤

Thank you for this video. It was concise and informative and exactly what I needed. Not being much of a plumber, I thought I was going to have to call one to fix my constantly draining toilet. Turns out it was just a cheap, easily replaceable gasket that I could fix myself in just a few minutes.

Videos like this make owning a home so much less of a headache THANK YOU

Mr Gilbert, thank you so much. Much Love from the Bay Area 🙏

Thanks this was very helpful! I was just about ready to pull the tank on this Mansfield not realizing it was unnecessary after seeing this video

I, too, am in the same situation. My gasket is not in the groove. Found your channel and now know what to do.!! Thanks.

Thank you so much! My $3 gasket has been driving me crazy for so long. I thought I had to replace that whole plunger assembly which forces a guy to take the top tank off. Thank you so much! You are truly awesome!

Not far from you in Oxford, just had the pink gasket break, exactly what I needed, thank you sir

You're the man. I just went to fix my Mansfield and had no clue what to do without the standard flapper...

Great/helpful video. First time I've seen these in my house and a bit foreign as I'm used to the other type of flapper. This helped explain how this works and what I need to get to fix. Thanks!

Thank you for this video, very helpful, short, & just what I needed to stop the "dreaded" refilling of the reservoir. I even installed a new fill valve first thinking it was the problem...still kept refilling so did some homework & this was the answer, thanks again Mr. Hardware.

I was able to fix my toliet after watching this video. Thank you!!

That was SO easy! Great explanation. I am not handy with tools, I can barely use a screwdriver. I have to keep repeating righty tighty, lefty loosy just to remember screwdriver 101 😁

Thanks a million!!! A video straight to the point that truly helps.

Wow - I had that gasket jammed on the bottom and then too tight. As soon as I put it on "loose", it worked. Thanks again for that helpful hint.

Super helpful, I was about to but a new toilet, just because I had gasket placed incorrectly and was scratching my head why water leaking sound is coming. After watching your video it was a quick fix. You saved me $$$ ,time and from frustration.

Great video, reminds me of my wood shop teacher back in 84. He was the coolest teacher in the school.

Thank you! The directions that came with my kit weren't great. So I was unsure where to put the gasket. I guessed wrong and it still leaked. This got me to put it in correctly

Just the info I needed. Thank you for saving me an expensive fix. The Plumbers trip alone is $90! + Parts and labor!

Just another comment about the seal. It may not leak water into the tank, but if you have a hard time pushing down on the flush handle, the seal is probably deformed causing the tower section to not lay on the seal but push down and stick to it. Better to replace the $2 seal than having to also buy a new handle (~$6) because it broke while trying to force it down to flush. I learned that from experience with kids who don't tell you when thinks aren't working right.

Great video! Very good information and it was a delight to hear you teach it. Thank ya sir.

Thank you so much man I just got my new house and have never seen this style before thank you 🙏

Gave your video a like. Helped me conduct a quick repair on my old Mansfield toilet.

Thanks for this video! You saved me a lot of time and inconvenience today !!!
