How to Repair a Mansfield Flush Valve



if you have a Mansfield toilet and you have their 210 or 211 flush valve it's very unique compared to the normal flap you'd see in most toilets so for this I've already turned off the valve and I flushed the toilet and the seal itself is actually connected to the overflow pipe here so the first step would be to remove the overfill two out of the top and then we're going to have to unscrew this top stop here and this keeps the two from going up too far and now we're actually going to remove the whole tower and there's a couple styles you can either have one that has the chain connected to the bottom there's another style or the chain is up high or instead of a chain you actually might have the handle pushing through the top here alright now that the overflow pipe is removed we're going to get right down to the seal so the easiest way to remove this is just grab it and pinch it and pull it out to the side and there's actually two grooves in the bottom of this flush valve and so we have the new seal and it's important that we get this into the top groove and so we'll set it down and we're just going to weave it into the top here and work it all the way around and once it's in you kind of test it by grabbing it and pulling it and you can see it locks itself right into this top groove so that all we need to do is take the tower and we'll slide it right back down over the center mast here and then we're going to take this cap screw it back on and then put our refill tube in the top and then we'll fill it up and give it a test alright so I filled the tank and you can't hear it leaking so we've got a solid solid seal here and those are the steps to change a flush valve for a Mansfield toilet

    I hope you read comments for old videos because I have this style (the tower is the bar, not the chain one, but everything else is the same) and need help. This exact thing you're doing is what I'm trying to do, but I can't because the old valve seal has major degradation, so I can't just "pull it out". The parts I pull fall off then there's nothing left to pull on. I've tried for an hour and all that it's gotten me are actual cuts from inside the toilet. How do I get this seal off when it's falling apart and there's no more places to grab?

    I was just about pulling my hair out trying to do this, and then I watched your video. 30 seconds later it was fixed. Thank you.

    Thanks, just came across a reference to a Mansfield flush valve in the instructions for a universal tank lever, and didn't know what they were. After watching your video, now I know, and knowing is half the battle. ?

    THANK YOU!! I didn't realize there was a top groove and put the seal below that and couldn't figure out why it was leaking worse. Thank you for taking the time FIX IT Channel to post and explain for others. The wife thanks I'm a plummer now. :-} Score for points!

    Hi, I'm working on replacing my Mansfield flush valve with a fluidmaster duo flush unit. I have the bowel off the toilet, but can't figure out how to remove the Mansfield center / tower part. There is no nut holding it on from the bottom. any advice on how to remove? Thanks!!

    Yes, rotating the seal around 360 degrees is critical to seating the seal.

    Make sure you take the seal once seated and rotate it round the groove area.  This ensures it seats properly

    I had to end up putting it on the second groove……for some reason mine continued to leak when I put it in the first groove……weird!

    I have been trying to stop a slow leak since September. I viewed this video last night, which was the first time I learned that it was absolutely essential to place the seal in the top groove. (I assumed it needed to be tight against the bottom.) So far, so good. Many thanks!

    that's the exact toilet i have, the model number inside the tank is kinda "gone", smudged beyond recognition, i got the toilet in 10/99, i've been having to tap the "flush button" a few times to seat the valve sometimes to stop the dribble "flow". that's so easy to fix! thanks for the video! it's a $2 part at the Home Depot down the street, sweet!

    Thank you for your video.  Took a picture of the flush valve to my hardware store & was told the only solution would be to replace the flush valve.  After watching your video I replaced the seal in a few minutes and voila, no more leaking.  All for a few dollars.

    Thanks for this video! I installed the new seal and was still having problems with the tank leaking to the bowl. I thought I needed to replace the black gasket as well, but thanks to comments by you and others I saw that was not my problem, as I wasn't leaking onto the floor. After cleaning the tower with CLR and reseating the seal into the first groove, all is well. Thanks!!!

    What if I've replaced the seal and it's still leaking into the bowl? is there a way to replace the gasket that goes from the tank to the bowl?

    I wore open toe black shoes with black socks and held my breath when looking directly into the toilet bowl, in addition to all the other suggestions which are great. Got it to work on the second try! Please feel free to add mine to your list.
