Product Overview

Only Fluidmaster has toilet flappers with built-in Microban protection. The Microban protection keeps the flapper cleaner by fighting flapper breakdown due to bacteria on the flapper itself. Toilet flappers made with Microban technology are more resistant to premature deterioration than other flappers. The Microban additive operates on the cellular level to prevent uncontrolled growth of microorganisms that can damage the flapper. The 502 Universal PerforMAX High Performance Toilet Flapper for 2 in. flush valves works best in toilets with 1.28 - 3.5 Gal. per flush or higher. The 502 is adjustable for optimum performance and water savings, is chlorine resistant, and has a solid frame for ultimate reliability. Flappers with a solid frame do not twist and provide the best seal. Replace or fix your toilet flapper with a Fluidmaster toilet flapper.

Fluidmaster Adjust-a-Flush 2" Toilet Flapper ---how does this adjuster work? What happens in turning the dial?

Asked by: Anonymous
Set to "9", the flapper will stay up for a long time. Smaller numbers will make it drop faster, limiting the amount of water that makes it out of the tank before the flapper stops it.

How to get the flapper to go down by itself?

How to get the flapper to go down by itself?
Asked by: nuhippy
I just sat over the exposed back basin of the toilet with a phillips head screw driver and made very minor adjustments to the screws on the inlet pump. Then I clipped the plastic off the flush handle innards in the water basin. That way as the flap descended it would not catch anything on the way down and restrict the toilet from stopping when needed.

how do I treat ghost water loss?

I hear water running out and I hear more water going in. What is going on?
Asked by: seacaptain1
The most common solution for your situation is to replace the flapper. As the flapper ages the material it is made of can disintegrate causing it become distorted and not to seal correctly on the tank discharge valve. You may also try lifting the flapper valve and looking for an obstruction that would cause the flapper not to seal properly.

2 in. Universal PerforMAX High Performance Toilet Flapper with Microban is rated 4.3 out of 5 by 215.
Rated 1 out of 5 by from Fatal flaw I installed this flapper a year ago, and today was the third time that the toilet ran overnight, resulting in an empty well. This time, I determined what the issue was. The problem lies in the design of the hinge. The vertical features ("walls") that create the pivot point can engage the flanged ends of the hinge pins of my overflow tube, causing it to "lock" into a fixed position. This happens very rarely, and when it does, it holds the flapper just low enough to convince you that it's closed. I spent 60 seconds modifying the inside edges of those walls (beveled them in towards the pivot) with a Dremel, and now the valve works as intended. I'd stay away from this product.

I flushed the water to empty the tank. I used a small wire to hold the part up that lets the water back into the tank. Once the water emptied out I remove the old leaky flapper and this new flapper fit on the prongs first try. I found the chain was a bit long. I did not want to cut it and make a irreversible error in judgement. So I simply put a loop on the hook and after two tries I said "Senior Girl Power, I did it"

The adjustable setting gradually changes over a few days & required a readjustment to restore the full flush. When removing the unit to make this change, the right side ear broke off. Apparently exposure to a week of cold Texas Panhandle water temperatures was more than the ear could take. Repair was not possible, unit discarded. Replaced it with a lower cost, non-adjustable Fluidmaster flapper which works fine & is more flexible.

I have used the Korky flappers for several years and constantly experienced it hanging open and not closing. Well, this time I spent about $6 including tax and purchased this flapper. It is simple and works perfectly! It never hangs and is designed such that it can't hang open. Great product and super price.

Rated 1 out of 5 by from Unhappy The chain keeps sticking to itself causing the flap to remain open and the toilet to run, which completely defeats the purpose of why I bought this in the first place. I would return it but have already thrown away the packaging. I prefer zero stars but the app doesn't allow that option.

Rated 5 out of 5 by from Works as advertised Installation of this product was fairly simple and straightforward. The entire process only took slightly over five minutes. This, coupled with a fairly reasonable price, turned the irritation of a non flushing toilet into nothing more than a momentary inconvenience.

I was tired of hearing the toilet fill several times a day and this fixed the problem. Good thing since I noticed my water bill went up last month. Hopefully it will now go back to "normal".

Decided to replace this part since I was replacing the water flow device, to have all new parts in the commode. It was very easy to install and has done the job so far. I measured the length of the chain on the old one to make sure it was the proper length
