Review: fluidmaster 540 replacement - package arrived open, not sure why but it could have definitely happened in shipping, I installed it and adjusted the chain and it seems to be working perfectly, if you have a fluidmaster 540 3 inch these will be a good replacement if needed, the quality of the flapper seems to be pretty good
Review: Much better than the one that came with the toilet - My old toilet flapper had warped over time, and our toilet tank had started refilling almost constantly due to the failed seal. The rigid structure to the flapper means it won’t warp over time like the cheap rubber one that came with my toilet. It stopped the problem immediately upon installation. Installing and adjusting this new flapper is also MUCH easier than the old one, because the piece that fastens to the lever is a much more practical design. The “bulb” is really interesting as well; you can turn it to let in more or less water, which causes it to float longer or sink faster, thereby closing the drain slower or faster, depending on how much water you want to use or how strong of a flush you want. I chose to keep it all the way closed, so it stays full of air and floats on top of the water as it drains down. This causes almost the entire tank to drain before the flapper closes. I did test it with the bulb at different levels and it makes a BIG difference in how quick it closes and how much water gets used, but the toilet I was installing this on has issues flushing sometimes, so a stronger and more consistent flush is part of what I was looking for. Pros: • Works great • Won’t warp over time • Adjustable water-saving feature • Easy to install and adjust Cons: • A bit more expensive than some of the other options. I needed two new flappers, but chose to only buy one to make sure it worked. Despite it being more expensive, it was so easy to install and fixed my problem so immediately that I came back and bought the same one the next day.

### ⭐⭐⭐⭐⭐ super easy install and removal
*by M***O on January 9, 2024*

Just gotta say, these newer type flappers are great. They have a snap on end that goes on the tube side that was pretty easy to snap on, much easier then wiggling the rubber off those end pieces that stick up. I had to remove it once to adjust the water, so it just snapped off just as easily. To adjust flush water amount, that clear bulb like thing, just pull up on it and turn it to adjust it to the number, higher means it flushes more water. I set it to 9, which my toto toilet supposed to use 1.3 gallons i think at setting 6, but i found that i prefer it to flush more water down to insure there are no clogs. So far so good, but when i first installed at 6 not only was the water level lower but seemed to flush much less water. I adjusted my korky fill valve, which is highly recommend, super easy to adjust fill level. So water was only filling up half way but after adjusting the fill valve toilet works great as it always has and this flapper seems much more heavier duty since it uses more plastic then the rubber which with hard water tends to deform after time and you get the middle of the night leaks or ghost flushes lol. So do i recommend this, yes it worked great and it seems universal for most modern toilets that have a 3" opening.
