Rated 3.7 out of 5 by 24 reviewers.
Rated 5.0 out of 5.0 by Great product after I ditched the instructions. Three different plumbers told me nothing could be done regarding my 50+ year old toilet's inability to seal properly and my only option was to replace the whole toilet. The problem was that the old style flapper was just a round ball on a long rod that slid up an down and it rarely slid down into the hole properly to where it would seal. The reason the plumbers gave as to why the whole toilet needed replaced was that there was no means of mounting a new style flapper as the proper attachments weren't in place and there was no way to add them based on the antiquated tank design. Then I found this product and it seemed like the perfect solution to the problem. And it was... until it wouldn't stick. I had cleaned and prepped the porcelain surface as the instructions indicated and the putty molded to the surface nicely but even the slightest pressure caused it to lift off. The putty just would not stick to the smooth porcelain surface. After a good night's sleep, the solution came to me. I carefully rolled the putty away from the outer edge of the ring and kneaded it toward the inside edge, forming somewhat of a triangular cross section. I removed the flapper part to where I could get full access to the top of the ring and then pushing down using the bottom of an aerosol can I was able to push both firmly and uniformly, seating the ring the to where the putty was actually gripping the inside rim of the opening rather than just trying to stick to the slick top surface. Worked like a charm. After reattaching the flapper, I gave a few stiff tugs on the chain and the unit gave no indication of wanting to come free. For someone who does plumbing for a living this should be a no-brainer. In that three different plumbers wanted me replace the entire toilet and spend money unnecessarily all I can say is that I now have a list of three plumbers I won't be calling again. P.s. for anyone having a problem just with the general lack of stickiness, knead the putty a bit. Once I started rolling the edges it got a lot stickier. The wax paper cover these come with was not a good idea as it appears more wax was stuck on the putty than stayed with the paper. April 27, 2015
Rated 1.0 out of 5.0 by Don't buy I bought this now it leaks more now then it did before, the flapper is not seating right after every flush I have to readjust it to get it to quit running. May 19, 2015
Rated 5.0 out of 5.0 It Works If You follow instructions on preparation of where the ring is glued down. Bought this at Home Depot in Roseville, Michigan. At first I was a bit sceptical due to the low price. I had no other choice unless I dismantled the toilet to replace the ring that the flapper sits on. What I did was drain the tank, wipe it out good after sanding and roughing up the old ring. I let it dry for about 3 hours. I then applied the silicone and let it dry overnight. That is the key for success with this kit, preparation and letting the adhesive dry for 24 hours. It has been a tear now and it is still working fine. July 23, 2012
Rated 1.0 out of 5.0 by Wrong Picture I have bought the product pictured before and it works. Unfortunately what is pictured is not what is sold. That black box on top of the flapper is not included in the the package that is sold. For some reason our Sterling toilets don't work with regular flappers. When you flush the flapper closes instantly so the only way to get a full flush is to hold the handle down until all the water drains out of the tank. The item pictures has a black box (water reservoir) with small holes so that when you flush the weight of the water keeps the flapper open, the water slowly drains out and then the flapper closes. Great product but not what is sold via this part number. September 2, 2014
Rated 5.0 out of 5.0 by Simple to install, good instructions provided, great fix for leaky flapper Was surprised at how easy it was to install. Originally, I'd replaced the flapper in the tank, then realized the fill valve would turn on every 30 mins or so to refill the tank. I had bought and used a "universal" replacement flapper that says it "fits most tanks". Then reading forums online, I realize that many homeowners also had to deal with leaks around the brand new flappers they'd just installed to replace their worn ones. Realized then from postings that many older toilets have larger seats for larger tanks whereas the newer toilet tanks are built smaller to meet water conservation standards. New flappers are likely made to fit well with newer tanks and are too small for some older ones. My house was built in 1978 so I guess that's why the new flapper ended up being the cause of the leak it was supposed to stop! This product comes with a flexible adhesive ring that you plop over the your old drain seat and all that's needed is a firm press to fit the mold over it. Then the flapper assembly gets put over that ring and sticks to it. Great way to ensure a good, leak-proof fit everywhere. September 17, 2012
Rated 4.0 out of 5.0 by Lasts a long time Wish I could find a flapper with a REAL chain on it. I have used these for years and the biggest problem is the plastic chain breaking. Tried many different ways to repair the chain, but wound up changing the whole assembly again. April 24, 2014
Rated 5.0 out of 5.0 by Working so far This seems to work so far. I tried a number of other flappers available at HD, but none seemed to work. My toilets are from the late 70's early 80's and the current 2.5" flappers are just slightly too small, since the opening on the valve is also about 2.5". I put this in when the tanks were dry and was able to mate the base to the valve without an issue. Despite having older toilets, I don't seem to need the additional counterweight cup that attaches to the top of the product. Actually, I couldn't use the counterweight on one toilet because it has a ball float that would trap the flapper in the up position. Overall, I am happy so far, and hopefully will stay that way.

Rated 5.0 out of 5.0 by Exactly as adveritised. Biggest thing with this kit is to makes sure the mating surfaces for the adhesive ring are bone dry. The instructions even recommend using a blow dryer to dry them up. Other than that, follow the instructions and you are good to go. I did not wait a 24hr period before filling the tank as some have suggested, and have had no problems 24 hrs after install. A very simple solution. 5yr warranty. August 19, 2012
