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

After watching some YouTube videos wondering what the cause of my toilet randomly running every 20 minutes, I decided to purchase this to give it a try. It was so easy to install and it worked! This product was less that $3, cheaper than Home Depot and ace hardware. It really works!

I have 3 towels that need to have this ring replaced. The package comes with instruction and the replacement process is easy. I usually order 3+ at a time so I can have extra for when I need them.

Easy fix but be advised that the toilet might run for a bit after installation. After a day or two, the seal sort of relaxed and molded itself to form a watertight seal.

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.

Can't believe this is all we needed to fix our toilet. So much easier to flush now that we installed this seal

This worked perfect now there’s no slow leak or loud noise after flushing!

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.

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.

washer did the trick.
