Korky Toilet Flush Valve Seal Fits Mansfield 210 and 211

I always keep a couple of these in the garage. I have the Mansfield brand and this Korky brand I just recently installed it and a size was perfect and installed very easily. I can't vouch for the durability yet because I just put it in yesterday. However I will report back after a while to let everyone know how it is holding up

A couple of years ago, people in my neighborhood were complaining that their toilets were getting hard to flush. In other words, pushing down the flush lever was getting difficult. Then mine started doing it, too. Some neighbors called out the plumber to the tune of $75 for the fix. One neighbor decided to replace the entire toilet! I got on the internet and discovered that the problem was that this little rubber gasket wears out pretty quickly and needed replacement. Surely, it wasn't THAT easy. I bought one. It was as easy as turning off the water valve, flushing to drain the tank, removing the little water fill tube from the top of the float stack in the middle of the tank, screwing off the top of the stack, removing the housing, taking off the old gasket, putting the new gasket on, and then putting all of the stuff back. Just be sure that the gasket is seated in the groove around the base of the stack. And, some people may have a hard time getting around the lever trip handle but I always just move mine out of the way. There are instructions all over the internet to help with this. It took more time to type this out than it did to replace the gasket. Yes, we sent an email out to the neighborhood letting everyone know what an easy fix this was. Now, I just keep a couple of these on hand and replace the gasket if that lever handle starts getting hard to push down. I mean, that shouldn't be the hard part about going to the toilet in the first place.

This will fix your toilet if it is either hard to push the flush handle, OR, if it keeps losing water from the tank and keeps running a few seconds to refill the tank that is leaking water into the bowl. I was confused by the description that it fits all 210 and 211 because I thought that was the toilet number, and mine is Mansfield 140. The 210/211 is the part number of the flush assembly that goes up and down. Mine actually has the water saver version in it, which doesn't matter, as this matches the size of the flush hole in the bottom of the tank. First look at the top of the flush device and see a flat round piece on top where the overflow tube goes in. Remove the tube and unscrew the round disk counter clockwise. Without that, the tall flush device will lift out, and you will see the old red washer at the bottom. When it is going bad, it will swell and make it hard to push the flush lever. When it is ruined it will start letting the water leak out of the tank and you will hear the water run a few seconds again to refil what the tank lost. Remove that old seal and put the new one in. There are usually 2 ridges and you want the red seal to be between those ridges. So work it around until it is under the top ridge and now it is between the two of them. Should there only be 1 ridge, work the red seal over it and make sure it is up against the bottom of that ridge. Clean off the edge of the "up and down" flush piece, so there is no sediment to keep it from sealing completely, and place it back in the tank, on top of the new flat red seal. Screw the top disk back on, put the overflow tube back in, and test flush before putting the lid back on, waiting to make sure you hear no water come back on in the tank. I have suffered with a mal-functioning toilet for a long time, and it was done if 5 minutes! If you have any doubts, there are many videos on youtube, just search Mansfield toilet running.

I had a 10 year old toilet that started to regularly not seal, letting water flow from the tank into the bowl. The flush valve seal didn't look good, so I got this to replace it. It was very easy to do (~ 2 minutes after watching a youtube video), and I haven't had any leak since.

Save time and money, fix your own leak under for under $5. Plumber would charge $100 or more.

If you have a Mansfield type toilet with the flush tower this is what you need. Fits perfectly. Just be careful to ensure the Korky is in the right grove at the base of the flush tower for the whole circumference of the base. It is easy to look at the seal and think it's sealed but it may not be. Double check.

If you have a toilet that runs intermittently and no leaking water on the floor, you most likely need a new one of these. It took me less than 5 minutes to install, and our toilet is good as new. Steps sans non-technical terms: 1) Turn off water supply to toilet and remove tank cover. 2) Flush toilet, holding handle down until as much water as possible drains out of the tank. 3) Pull the little tube out of the cap thingy, then twist off the cap. 4) Remove the tall flush tower thing. (You have to push it sideways a little at the top to unhook kit from the long bar connected to the handle. 5) Reach down and remove the old seal. 6) Install the new seal, making sure that it fits snuggly all the way around in the top groove of the hole at the bottom of the tank. 7) Put it all back together in reverse order, and turn the water supply back on. No tools required! Super easy!

Like some unfortunate homeowners, I too was cursed with the builder having installed the cheap Mansfield 210 toilet. And as I was fooled by false advertisements into putting the cursed bleach tablets into the tank, it naturally lead to the rubber valve getting damaged and flush getting stuck... And like most homeowners I kept avoiding the issue even when it required considerable strength to flush the toilet. One fine day the stars misaligned and my futile attempts to use the malfunctioning stuck flush lever led to breaking the stopper mechanism. And if you have a Mansfield toilet, you probably know that fixing the broken stopping mechanism meant removing the entire tank; it was at this point I realized that my problems of a stuck valve could have been solved under a minute by just replacing this valve seal...OMG..... after wasting 1 hour to replace the entire stopping mechanism i immediately ordered 3 valve seals to replace my other toilets which were also acting up. all of them were replaced under 2mins... saving me a lot of grief down the line. So if you are in the habit of putting bleach tablets and if your flush handle require considerable effort to operate, save yourself the future grief and money, stop using the bleach tablets and replace the flush valve seals for cheap. Do not wait till you break the stopping mechanism..

washer did the trick.
