5.0 out of 5 stars super easy install and removal
Reviewed in the United States 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.

5.0 out of 5 stars 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.

4.0 out of 5 stars Quality flapper with advantages over OEM to help save water
Reviewed in the United States on April 17, 2022
I used for Tot o Drake. This flapper is different than the original in that there is a rigid plastic frame. Most flappers are all rubber but on this one only the seal is rubber and it is silicone rubberrubber for more durability and better seal. Hopefully this will make it last longer.
The chamber needed adjustment but the instructions were clear. The chain was too long and will require cutting to avoid it getting between the seal surface.

After adjusting it appears to work will with toto eco drake however seems to stop flushing earlier than original but flushes completely. Will give update after using for a while but early report is to recommend this product over the all rubber model.
Fluidmaster has excellent quality and so far I am impressed with this.

The better seal will help stop water waste in the toilet which is the biggest water user in the home. Important as I live in Vegas and water is expensive!

5.0 out of 5 stars Inspires confidence - And now time-tested: 9 years!
Reviewed in the United States on October 20, 2013
Easy to install. Instructions were adequate. Expensive, but if it works a long time, will be worth the money. For my Toto toilet, it seems the 'spread' adjustment for the pivots needs a spot in between A and B. I put them in between, but there is no detent, so I don't know how well it will stay. Adjustable flush volume is a nice idea. I have not checked to see if the default setting of '10' causes my 1.6 gpf toilet to use more water than it needs to. If it survives the durability test, I may work on fine-tuning the flush volume.
The original Toto flapper is a disaster. It is made of soft rubber/elastomer and is not rigid enough to span the 3" flush port. The weight of the water in the tank eventually deforms the flapper until it leaks. Only lasted a year or so. The rubber doesn't degrade, the flapper just deforms till it can't seal properly anymore.
This Fluidmaster design appears to address this issue by using a rigid plastic structure to support the soft elastomer seal.
UPDATE-03/30/2014: This product has passed the 6-month point with no further issues; still functions as expected. In fact, I had forgotten about it until something else reminded me. (A good thing.) Bottom line... I'm happy so far.
UPDATE-08/23/2015: Now in service 22 months. No issues. I can say with confidence that it beats the original. I have hopes it will continue to serve well for several more years.
UPDATE-02/18/2017: Still working well at 40 months. No issues or adjustments. I had (again) forgotten about it until a friend told me about their own toilet maintenance trouble. I can definitely recommend this flapper.
UPDATE-05/5/2020: Still working well after 6.5 years. A few months ago, I began to hear the toilet refilling on its own - a sure sign of leaking. However, I removed the flapper, cleaned the elastomeric seal and reinstalled it (because it looked fine). No more spontaneous refilling; it's still working well.
UPDATE-09/16/2022: Still working in the Toto. 9 years. I have not seen any evidence of bubbles forming in the seal as reported in more recent reviews. Hopefully, Fluidmaster has not changed the material or process.
