Fluidmaster 504 2-Inch Universal Chlorine Resistant, Long Lasting Flexible Frame Toilet Flapper , Red

Just follow the directions on back. I didn't even shut the water off. I brought some stainless wire wool to clean dishes and a scissors and set them on the counter. I opened the flapper valve package and set it on the counter. I flushed the toilet and while the water was running out I scrubbed the seat that the water was going through with the stainless steel wire wool for pots and pans. The flushing of the tank cleaned it all out. I just removed the old one by pulling it off of the 'ears' sticking out of the standpipe with one hand while holding up the float with the other. I checked the new one for size and fit (the long droopy side with the hole in it goes down). Then I held the float and flapper valve in the same hand and with the other hand cut the center doodads out with two snips of the scissors being careful not to drop the cutout into the flush hole. You'll figure it out. The directions on the package back and the float valve both indicate where to cut. I did two cuts where the float valve said 'cut' and then slipped the rubber arms of the float valve over the standpipe ears with one hand while still holding the float up with the other. Remember the oblong part with the hole goes down. I flipped the float valve up and down a couple of times to make sure it was seating roughly close and to ensure it wasn't binding. Then I used the old float valve next to the new float valve and checked the chain length. With the new float over the flush hole, I let go of the float and allowed the tank to fill while I adjusted the new chain length and clipped it next to the old float valve chain attachment being careful not to yank and flush the toilet. It wouldn't matter if it did - I just didn't want to waste more water. Done. And it works like a jewell.

This is a great flapper for an older toilet ! My toilet in my basement is from the 1970's and was running from time to time . I installed this Fluidmaster flapper and problem solved no more running toilet . Was very easy to install too,I didn't even have to turn the water off ! I highly recommend this flapper if you have an older toilet . It says right on the package before 1994 !

The plumber wanted $50 to come out and take a look at why our toilet kept running. Since toilets are pretty darned simple mechanisms, I took the lid off the tank and immediately spotted the problem: the flapper hinges had DISINTEGRATED. I placed the plug back into the hole & ordered this inexpensive replacement from Amazon. With much love to Amazon Prime, this flapper arrived THE NEXT MORNING! The flapper comes packaged nicely with instructions. Our toilet didn't need the ring/hinge portion of the flapper, so following the instructions, I carefully snipped that part off with a pair of regular scissors at the line marked "SNIP". Lo and behold, there was my disintegrated flapper's TWIN! I turned off the water supply to my toilet and took the tank lid off. Flushed the toilet to drain the tank. Removed the old, funky, disintegrated flapper and threw it away, SAVING THE CHAIN. Installed the new flapper by fitting the holes on the hinge to the hinge arms sticking out on either side of the long tube thingy. I then made the chain on the new flapper the exact same length as the old chain. (This saves you from having to figure out the best length for the chain that leads to the toilet lever, which lifts up the flapper to let the water drain out.) Hooked the chain to the toilet handle. Turned the water supply to the toilet back on. Flushed the toilet. LO AND BEHOLD! The flapper worked like a champion! VICTORY DANCE! I used the money I saved not calling the plumber to go out for a victory dinner. :) Seriously great quality flapper for very little money. You can do it too!

I works that is all I can say about the item. It did connect easily and price was right!

exceeds quality expectations, & hence, a good value for the price

Save me a lot of time

I had used one of these flappers for my downstairs toilet a couple years back, and it worked just fine. When the upstairs toilet needed a new flapper recently, I got another one of these again. The replacement went quickly and seemed okay initially. Unfortunately I found that this one had a slow leak in the seal, and I'd hear the toilet top off the tank periodically. I was thinking I'd need to replace the prior overflow and flush valve to better match the new flapper (and was not looking forward to the steps involved in that), but when I popped the lid off to take another look at it earlier today, I noticed the chain to the flapper seemed almost taut. I detached the chain and attached it again with more slack. No leaking since then! =D My initial estimate of which chain link to use was probably off, and was keeping it from getting a good seal.

Brought this to fix a toilet that kept running. Was inexpensive and did the job. No problems here.
