Korky 427BP Flush Valve Seal For Mansfield 210 and 211 Toilet Repairs , Red

Easy replacement to stop slow leak to bowl because of cracked original gasket on flush valve assembly. Check to see if it is just dirty due to hard water first. If cracked or torn, this works great. I keep one on hand always as a spare. These are also readily available at local stores at similar prices.

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!

The problem with these seals is they work fine for about a year but then the water deteriorates the seal and you have to replace them annually. Bad rubber or whatever I don't know

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.

Works well but doesn’t last as long. I wish there was an advancement to make these more durable to last longer but was a great price compared to in store

Toilet kept running, I kept putting it off, I finally got around to looking up the model number of the toilet, it's at least 20 years old. Looked to see what the issue was, where the leak was coming from, and this seal was the culprit. I looked up some youtube videos to make sure I was going to do it correctly. I looked up the model number on Amazon, and "Viola". Best price in town and next day delivery cant beat that. Have had it for a while, super easy to install. Absolutely recommend.

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.

My toilet had become increasingly hard to flush. It was difficult to press the knob. Odd. But this replacement gasket perfectly solved the problem. Less than 5 min install with no tools. The old gasket was 16 years old and had become worn and mis-shaped.
