Hard To Flush Toilet Remedies

- If the toilet becomes hard to flush at the handle, and has a sticking at the plunger bottom, it may mean the flush valve seal gasket needs to be replaced.
The rubber seal deteriorates, changes shape to conform with the float that sucks or sticks to each other making the handle hard to flush. So replace the rubber gasket on the flush valve.
First, look at these possible issues:
1. Check the Chain to see if the chain is snagging to something.
2. Check Chain length so when flushed, the flapper seal should rise and close again properly.
3. Check the Flapper isn’t worn out as they will stick or leak.
4. Check the Handle for binding, cracks and the nuts that hold the handle in place.
The flush valve rubber seal changes shape through deterioration to conform to the shape of the float and creates "vacuum" type feeling that sucks or sticks to each other making the handle hard to flush.
The flush valve is the device that controls how much water flows from the tank into the toilet bowl. Sometimes it looks like a flapper with a chain pulling up and down. A Mansfield toilet has a tower flush valve that lifts up and down. The seal on the flush valve is a rubber ring, and deteriorates, then sticks to the tower, stopping the handle from lifting the flush valve.
The flush valve gasket seals are common at hardware stores, though know or bring the old one.
Kohler gaskets 2 Pack, cost $7, yellow in color, and 2 red gaskets for Mansfield or American Standard are $6.
The plunger/float flush valve sits on the rubber ring. You want to make sure it goes back the same way. All you have to do is unscrew the center piece on the flush valve and loosen the flush lever and the center piece and the flush valve will pull off exposing the valve seal to be replaced.
Clean the bottom of the flush valve itself when you replace the seal, raise the flapper and clean it off.
Mansfield toilets come with a water saver flush valve, so a special handle fits through a loop to lift the seal.
Mansfield toilet flush valve seal replacement directions:
Turn off water.
1. Disconnect the handle.
2. Flush valve open so the water empties out.
3. Disconnect water refill tube from top of the flush valve, tower assembly, remove gently.
4. Unscrew the cap on top that the refill tube went into. It looks like a little flat donut on flush valve tower.
5. The whole valve tower will slide up and off, with the red gasket on the bottom.
6. Remove the old red rubber ring flush valve seal, it stretches.
7. Slide the new gasket into place in the groove. When fitted properly, you can rotate the ring in the groove.
8. Reassemble - slide the tower back on, screw on flat cap, connect the handle, and turn on the water.
Turn on the water.
The threads on the nut inside the tank are left-handed. They turn the opposite direction than most threaded fittings.
The worst ones are the solid flappers with a gasket on the bottom found on Kohler toilets and others.

Thank you thank you thank you. I’m a 78 year old woman and with your video I was able to fix my flusher. It was so easy. The hard part was turning the water off but with the help of a little WD40 I won the battle. Thanks again.
Thank you for posting! Searched all over for a reason that the toilet was hard to flush - went to the hardware store, bought these gaskets for under $2 each, replaced them (SUPER EASY), and they are back to normal again! Found this only after one of the handles broke. Thanks again for posting!
Thank you for sharing the knowledge, as a new home owner I'm working on figuring out all these little things 👍great video straight to the point
Great video. This is the exact problem I'm having. I'll try this out today. Thanks for your video. If I lived near your store, it would be my first stop when I had a problem to fix. I'm now a lifetime subscriber and will watch and like All your videos. Keep up the great work.
Thank you! Had a used toilet installed when I finished my basement bathroom. But it was always sticky! Went through 2 flush levers. Then, gasket popped off, so I find this video here. Saved me! I know just what to do now to fix the gasket and also won't have a hard to flush toilet anymore!
i replaced 2 broken handles before finding your video. many thanks
Broke my toilet handle off and this was the cause. Thanks for the clear and concise video.
Thank you from Harrison TWP. After replacing a broken handle it just got harder and harder to flush and I came across your video.
Thanks for the great video. I was going thru handles but the rest worked fine. I was puzzled why the handles were bending and breaking. Watched your video and replaced the seal and problem solved.
Thank you so much for this tip, broke several handles already
Thanks for the video! I was having this exact issue. I'll be fixing it today!
I love your videos Mr Hardware great 👍 Tip
Thanks. Looks so easy
Thanks for taking the time to post this !!
You are the best, I did it myself! Thank you for saving me so much money! 😊
Man that’s a clean tank!
Thank you very much
Easy fix to the problem. Thanks!
Thanks for the info
Thank you this makes sense.
Thanks Mr. Hardware! I'm a girl and I'm gonna repair my own toilet, thanks to YOU!
Thank u, thank u, thank u!!!!
If this works for me (I ACTUALLY have a stuck Mansfield) you'll be my hero today!!!! 🙏
Perfect, Just saved me a plumber visit.
I'm happy I found this video because this is exactly the problem I'm having.....except I have a plain ol' flapper type that is getting stuck over the hole. Do I just replace the entire flapper or is there a gasket somewhere on that mechanism as well? I've shortened the chain as much as I can without causing it to leak and it' still sticks. Thanks
The flapper is getting soft and sticky, replace it.
The problem may be your lever not the gasket. Try lifting the tower. If it lifts freely, its the lever that is the problem. Replace the lever.
I’m not sure what I’m doing wrong, I put the gasket in and I’m not sure what to grove you’re talking about yes they’re grooves but is this like there are several grooves. It’s not hard to flush anymore but now it’s leaking and I know it has to do with this gasket cause that’s the only thing that’s changed.
Update:
I have a Mansfield and a Kohler video showing more close-up of where the gasket goes. I don’t know which flush valve you have.
I wish I found this video sooner. I busted my handle and chain
Your lucky usually I'm 10 for 10 0n broken lift handle on these...
Thumbs up, but isn't there a lazier way, like Vaseline or something?
Not something that will last over a month.
My mom's toilet is now hard to flush but she has a different mechanism... :/
All flush valves have a replaceable gasket and I’ll bet that your gasket is old and has gotten soft and spongy and that’s why it’s sticking
